+Contributing to Bitcoin Core
+============================
+
+The Bitcoin Core project operates an open contributor model where anyone is welcome to contribute towards development in the form of peer review, testing and patches. This document explains the practical process and guidelines for contributing.
+
+Firstly in terms of structure, there is no particular concept of “Core developers” in the sense of privileged people. Open source often naturally revolves around meritocracy where longer term contributors gain more trust from the developer community. However, some hierarchy is necessary for practical purposes. As such there are repository “maintainers” who are responsible for merging pull requests as well as a “lead maintainer” who is responsible for the release cycle, overall merging, moderation and appointment of maintainers.
+
+
+Contributor Workflow
+--------------------
+
+The codebase is maintained using the “contributor workflow” where everyone without exception contributes patch proposals using “pull requests”. This facilitates social contribution, easy testing and peer review.
+
+To contribute a patch, the workflow is as follows:
+
+  - Fork repository
+  - Create topic branch
+  - Commit patches
+
+The project coding conventions in [doc/developer-notes.md](doc/developer-notes.md) must be adhered to.
+
+In general [commits should be atomic](https://en.wikipedia.org/wiki/Atomic_commit#Atomic_commit_convention) and diffs should be easy to read. For this reason do not mix any formatting fixes or code moves with actual code changes.
+
+Commit messages should be verbose by default consisting of a short subject line (50 chars max), a blank line and detailed explanatory text as separate paragraph(s); unless the title alone is self-explanatory (like "Corrected typo in main.cpp") then a single title line is sufficient. Commit messages should be helpful to people reading your code in the future, so explain the reasoning for your decisions. Further explanation [here](http://chris.beams.io/posts/git-commit/).
+
+If a particular commit references another issue, please add the reference, for example "refs #1234", or "fixes #4321". Using "fixes or closes" keywords will cause the corresponding issue to be closed when the pull request is merged.
+
+Please refer to the [Git manual](https://git-scm.com/doc) for more information about Git.
+
+  - Push changes to your fork
+  - Create pull request
+
+The title of the pull request should be prefixed by the component or area that the pull request affects. Examples:
+
+    Consensus: Add new opcode for BIP-XXXX OP_CHECKAWESOMESIG
+    Net: Automatically create hidden service, listen on Tor
+    Qt: Add feed bump button
+    Trivial: fix typo
+
+If a pull request is specifically not to be considered for merging (yet) please prefix the title with [WIP] or use [Tasks Lists](https://github.com/blog/1375-task-lists-in-gfm-issues-pulls-comments) in the body of the pull request to indicate tasks are pending.
+
+The body of the pull request should contain enough description about what the patch does together with any justification/reasoning. You should include references to any discussions (for example other tickets or mailing list discussions).
+
+At this stage one should expect comments and review from other contributors. You can add more commits to your pull request by committing them locally and pushing to your fork until you have satisfied all feedback. If your pull request is accepted for merging, you may be asked by a maintainer to squash and or rebase your commits before it will be merged. The length of time required for peer review is unpredictable and will vary from patch to patch.
+
+
+Pull Request Philosophy
+-----------------------
+
+Patchsets should always be focused. For example, a pull request could add a feature, fix a bug, or refactor code; but not a mixture. Please also avoid super pull requests which attempt to do too much, are overly large, or overly complex as this makes review difficult.
+
+
+###Features
+
+When adding a new feature, thought must be given to the long term technical debt and maintenance that feature may require after inclusion. Before proposing a new feature that will require maintenance, please consider if you are willing to maintain it (including bug fixing). If features get orphaned with no maintainer in the future, they may be removed by the Repository Maintainer.
+
+
+###Refactoring
+
+Refactoring is a necessary part of any software project's evolution. The following guidelines cover refactoring pull requests for the project.
+
+There are three categories of refactoring, code only moves, code style fixes, code refactoring. In general refactoring pull requests should not mix these three kinds of activity in order to make refactoring pull requests easy to review and uncontroversial. In all cases, refactoring PRs must not change the behaviour of code within the pull request (bugs must be preserved as is).
+
+Project maintainers aim for a quick turnaround on refactoring pull requests, so where possible keep them short, uncomplex and easy to verify. 
+
+
+"Decision Making" Process
+-------------------------
+
+The following applies to code changes to the Bitcoin Core project (and related projects such as libsecp256k1), and is not to be confused with overall Bitcoin Network Protocol consensus changes.
+
+Whether a pull request is merged into Bitcoin Core rests with the project merge maintainers and ultimately the project lead. 
+
+Maintainers will take into consideration if a patch is in line with the general principles of the project; meets the minimum standards for inclusion; and will judge the general consensus of contributors.
+
+In general, all pull requests must:
+
+  - have a clear use case, fix a demonstrable bug or serve the greater good of the project (for example refactoring for modularisation);
+  - be well peer reviewed;
+  - have unit tests and functional tests where appropriate;
+  - follow code style guidelines;
+  - not break the existing test suite;
+  - where bugs are fixed, where possible, there should be unit tests demonstrating the bug and also proving the fix. This helps prevent regression.
+
+Patches that change Bitcoin consensus rules are considerably more involved than normal because they affect the entire ecosystem and so must be preceded by extensive mailing list discussions and have a numbered BIP. While each case will be different, one should be prepared to expend more time and effort than for other kinds of patches because of increased peer review and consensus building requirements.
+
+
+###Peer Review
+
+Anyone may participate in peer review which is expressed by comments in the pull request. Typically reviewers will review the code for obvious errors, as well as test out the patch set and opine on the technical merits of the patch. Project maintainers take into account the peer review when determining if there is consensus to merge a pull request (remember that discussions may have been spread out over github, mailing list and IRC discussions). The following language is used within pull-request comments:
+
+  - ACK means "I have tested the code and I agree it should be merged";
+  - NACK means "I disagree this should be merged", and must be accompanied by sound technical justification. NACKs without accompanying reasoning may be disregarded;
+  - utACK means "I have not tested the code, but I have reviewed it and it looks OK, I agree it can be merged";
+  - Concept ACK means "I agree in the general principle of this pull request";
+  - Nit refers to trivial, often non-blocking issues.
+
+Reviewers should include the commit hash which they reviewed in their comments.
+
+Project maintainers reserve the right to weigh the opinions of peer reviewers using common sense judgement and also may weight based on meritocracy: Those that have demonstrated a deeper commitment and understanding towards the project (over time) or have clear domain expertise may naturally have more weight, as one would expect in all walks of life.
+
+Where a patch set affects consensus critical code, the bar will be set much higher in terms of discussion and peer review requirements, keeping in mind that mistakes could be very costly to the wider community. This includes refactoring of consensus critical code.
+
+Where a patch set proposes to change the Bitcoin consensus, it must have been discussed extensively on the mailing list and IRC, be accompanied by a widely discussed BIP and have a generally widely perceived technical consensus of being a worthwhile change based on the judgement of the maintainers.
+
+
+Release Policy
+--------------
+
+The project leader is the release manager for each Bitcoin Core release.

+Bitcoin Core integration/staging tree
+=====================================
+
+[![Build Status](https://travis-ci.org/bitcoin/bitcoin.svg?branch=master)](https://travis-ci.org/bitcoin/bitcoin)
+
+https://bitcoincore.org
+
+What is Bitcoin?
+----------------
+
+Bitcoin is an experimental new digital currency that enables instant payments to
+anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate
+with no central authority: managing transactions and issuing money are carried
+out collectively by the network. Bitcoin Core is the name of open source
+software which enables the use of this currency.
+
+For more information, as well as an immediately useable, binary version of
+the Bitcoin Core software, see https://www.bitcoin.org/en/download.
+
+License
+-------
+
+Bitcoin Core is released under the terms of the MIT license. See [COPYING](COPYING) for more
+information or see https://opensource.org/licenses/MIT.
+
+Development Process
+-------------------
+
+The `master` branch is regularly built and tested, but is not guaranteed to be
+completely stable. [Tags](https://github.com/bitcoin/bitcoin/tags) are created
+regularly to indicate new official, stable release versions of Bitcoin Core.
+
+The contribution workflow is described in [CONTRIBUTING.md](CONTRIBUTING.md).
+
+The developer [mailing list](https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev)
+should be used to discuss complicated or controversial changes before working
+on a patch set.
+
+Developer IRC can be found on Freenode at #bitcoin-core-dev.
+
+Testing
+-------
+
+Testing and code review is the bottleneck for development; we get more pull
+requests than we can review and test on short notice. Please be patient and help out by testing
+other people's pull requests, and remember this is a security-critical project where any mistake might cost people
+lots of money.
+
+### Automated Testing
+
+Developers are strongly encouraged to write [unit tests](/doc/unit-tests.md) for new code, and to
+submit new unit tests for old code. Unit tests can be compiled and run
+(assuming they weren't disabled in configure) with: `make check`
+
+There are also [regression and integration tests](/qa) of the RPC interface, written
+in Python, that are run automatically on the build server.
+These tests can be run with: `qa/pull-tester/rpc-tests.py`
+
+The Travis CI system makes sure that every pull request is built for Windows
+and Linux, OSX, and that unit and sanity tests are automatically run.
+
+### Manual Quality Assurance (QA) Testing
+
+Changes should be tested by somebody other than the developer who wrote the
+code. This is especially important for large or high-risk changes. It is useful
+to add a test plan to the pull request description if testing the changes is
+not straightforward.
+
+Translations
+------------
+
+Changes to translations as well as new translations can be submitted to
+[Bitcoin Core's Transifex page](https://www.transifex.com/projects/p/bitcoin/).
+
+Translations are periodically pulled from Transifex and merged into the git repository. See the
+[translation process](doc/translation_process.md) for details on how this works.
+
+**Important**: We do not accept translation changes as GitHub pull requests because the next
+pull from Transifex would automatically overwrite them again.
+
+Translators should also subscribe to the [mailing list](https://groups.google.com/forum/#!forum/bitcoin-translators).

-// Why base-58 instead of standard base-64 encoding?
-// - Don't want 0OIl characters that look the same in some fonts and

+# SYNOPSIS
+#
+#   AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
+#
+# DESCRIPTION
+#
+#   Test for the Boost C++ libraries of a particular version (or newer)
+#
+#   If no path to the installed boost library is given the macro searchs
+#   under /usr, /usr/local, /opt and /opt/local and evaluates the
+#   $BOOST_ROOT environment variable. Further documentation is available at
+#   <http://randspringer.de/boost/index.html>.
+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
+#
+#   And sets:
+#
+#     HAVE_BOOST

+#   AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
+#
+# DESCRIPTION
+#
+#   Check whether the given FLAG works with the current language's compiler
+#   or gives an error.  (Warnings, however, are ignored)
+#
+#   ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on

+#
+#   If EXTRA-FLAGS is defined, it is added to the current language's default
+#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
+#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
+#   force the compiler to issue an error when a bad flag is given.
+#
+#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
+#   macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

+# SYNOPSIS
+#
+#   AX_GCC_FUNC_ATTRIBUTE(ATTRIBUTE)
+#
+# DESCRIPTION
+#
+#   This macro checks if the compiler supports one of GCC's function
+#   attributes; many other compilers also provide function attributes with
+#   the same syntax. Compiler warnings are used to detect supported
+#   attributes as unsupported ones are ignored by default so quieting
+#   warnings when using this macro will yield false positives.
+#
+#   The ATTRIBUTE parameter holds the name of the attribute to be checked.
+#
+#   If ATTRIBUTE is supported define HAVE_FUNC_ATTRIBUTE_<ATTRIBUTE>.
+#
+#   The macro caches its result in the ax_cv_have_func_attribute_<attribute>
+#   variable.
+#
+#   The macro currently supports the following function attributes:
+#
+#    alias
+#    aligned
+#    alloc_size
+#    always_inline
+#    artificial
+#    cold
+#    const
+#    constructor
+#    deprecated
+#    destructor
+#    dllexport
+#    dllimport
+#    error
+#    externally_visible
+#    flatten
+#    format
+#    format_arg
+#    gnu_inline

+#    ifunc
+#    leaf
+#    malloc
+#    noclone

+#    optimize
+#    pure
+#    unused
+#    used
+#    visibility
+#    warning
+#    warn_unused_result
+#    weak
+#    weakref
+#
+#   Unsuppored function attributes will be tested with a prototype returning
+#   an int and not accepting any arguments and the result of the check might
+#   be wrong or meaningless so use with care.

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also link it with them as well. e.g. you should link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threads programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

-WINDOWS BUILD NOTES
-===================
-
-Compilers Supported
--------------------
-MinGW GCC (recommended)
-
-MSVC 6.0 SP6: You'll need Boost version 1.34 because they dropped support
-for MSVC 6.0 after that.  However, they didn't add Asio until 1.35.
-You should still be able to build with MSVC 6.0 by adding Asio to 1.34 by
-unpacking boost_asio_*.zip into the boost directory:
-http://sourceforge.net/projects/asio/files/asio
-
-MSVC 8.0 (2005) SP1 has been tested.  Note: MSVC 7.0 and up have a habit of
-linking to runtime DLLs that are not installed on XP by default.
-
-
-Dependencies
-------------
-Libraries you need to download separately and build:
-
-             default path  download
-wxWidgets-2.9  \wxwidgets   http://www.wxwidgets.org/downloads/
-OpenSSL        \openssl     http://www.openssl.org/source/
-Berkeley DB    \db          http://www.oracle.com/technology/software/products/berkeley-db/index.html
-Boost          \boost       http://www.boost.org/users/download/
-
-Their licenses:
-wxWidgets      LGPL 2.1 with very liberal exceptions
-OpenSSL        Old BSD license with the problematic advertising requirement
-Berkeley DB    New BSD license with additional requirement that linked software must be free open source
-Boost          MIT-like license
-
-Versions used in this release:
-MinGW GCC    3.4.5
-wxWidgets    2.9.0
-OpenSSL      0.9.8k
-Berkeley DB  4.7.25.NC
-Boost        1.42.1
-
-
-Notes
------
-The UI layout is edited with wxFormBuilder.  The project file is
-uiproject.fbp.  It generates uibase.cpp and uibase.h, which define base
-classes that do the rote work of constructing all the UI elements.
-
-The release is built with GCC and then "strip bitcoin.exe" to strip the debug
-symbols, which reduces the executable size by about 90%.
-
-
-wxWidgets
----------
-cd \wxwidgets\build\msw
-make -f makefile.gcc
- or
-nmake -f makefile.vc
-
-
-OpenSSL
--------
-Bitcoin does not use any encryption.  If you want to do a no-everything
-build of OpenSSL to exclude encryption routines, a few patches are required.
-(instructions for OpenSSL v0.9.8k)
-
-Edit engines\e_gmp.c and engines\e_capi.c and add this #ifndef around
-the openssl/rsa.h include:
-  #ifndef OPENSSL_NO_RSA
-  #include <openssl/rsa.h>
-  #endif
-
-Edit ms\mingw32.bat and replace the Configure line's parameters with this
-no-everything list.  You have to put this in the batch file because batch
-files can't take more than nine command line parameters.
-  perl Configure mingw threads no-rc2 no-rc4 no-rc5 no-idea no-des no-bf no-cast no-aes no-camellia no-seed no-rsa no-dh
-
-Also REM out the following line in ms\mingw32.bat after the mingw32-make
-line.  The build fails after it's already finished building libeay32, which
-is all we care about, but the failure aborts the script before it runs
-dllwrap to generate libeay32.dll.
-  REM  if errorlevel 1 goto end
-
-Build
-  cd \openssl
-  ms\mingw32.bat
-
-If you want to use it with MSVC, generate the .lib file
-  lib /machine:i386 /def:ms\libeay32.def /out:out\libeay32.lib
-
-
-Berkeley DB
------------
-Using MinGW and MSYS:
-cd \db\build_unix
-sh ../dist/configure --enable-mingw --enable-cxx
-make
-
-
-Boost
------
-download bjam.exe from
-http://sourceforge.net/project/showfiles.php?group_id=7586&package_id=72941
-cd \boost
-bjam toolset=gcc --build-type=complete stage
- or

-
-Mac OS X build instructions
-Laszlo Hanyecz (solar@heliacal.net)
-
-
-Tested on 10.5 and 10.6 intel.  PPC is not supported because it's big-endian.
-
-All of the commands should be executed in Terminal.app.. it's in
-/Applications/Utilities
-
-You need to install XCode with all the options checked so that the compiler
-and everything is available in /usr not just /Developer
-I think it comes on the DVD but you can get the current version from
-http://developer.apple.com
-
-
-1.  Pick a directory to work inside.. something like ~/bitcoin works.  The
-structure I use looks like this:
-(~ is your home directory)
-
-~/bitcoin
-~/bitcoin/trunk         # source code
-~/bitcoin/deps          # dependencies.. like libraries and headers needed to compile
-~/bitcoin/Bitcoin.app   # the application bundle where you can run the app
-
-Just execute: mkdir ~/bitcoin
-This will create the top dir for you..
-
-WARNING: do not use the ~ notation with the configure scripts.. use the full
-name of the directory, for example /Users/james/bitcoin/deps for a user named
-'james'.  In my examples I am using 'macosuser' so make sure you change that.
-
-2.  Check out the trunk version of the bitcoin code from subversion:
-
-cd ~/bitcoin
-svn checkout https://bitcoin.svn.sourceforge.net/svnroot/bitcoin/trunk
-
-This will make ~/bitcoin/trunk for you with all the files from subversion. 
-
-3.  Get and build the dependencies
-
-
-Boost
------
-
-Download from http://www.boost.org/users/download/
-I'm assuming it ended up in ~/Downloads..
-
-mkdir ~/bitcoin/deps
-cd ~/bitcoin/deps
-tar xvjf ~/Downloads/boost_1_42_0.tar.bz2
-cd boost_1_42_0
-./bootstrap.sh
-./bjam architecture=combined address-model=32_64 macosx-version=10.6 macosx-version-min=10.5 link=static runtime-link=static --toolset=darwin --prefix=/Users/macosuser/bitcoin/deps install
-
-This part takes a while.. use your judgement and fix it if something doesn't
-build for some reason.
-
-Change the prefix to whatever your directory is (my username in this example
-is macosuser).  I'm also running on 10.6 so i have macosx-version=10.6  change
-to 10.5 if you're using leopard.
-
-This is what my output looked like at the end:
-...failed updating 2 targets...
-...skipped 144 targets...
-...updated 8074 targets...
-
-
-OpenSSL
--------
-
-Download from http://www.openssl.org/source/
-
-We would like to build this as a 32 bit/64 bit library so we actually build it
-2 times and join it together here..  If you downloaded with safari it already
-uncompressed it so it will just be a tar not a tar.gz
-
-cd ~/bitcoin/deps

-
-Verify your binaries
-
-file lib/libcrypto.a
-
-output should look like this:
-
-ib/libcrypto.a: Mach-O universal binary with 2 architectures
-lib/libcrypto.a (for architecture i386):	current ar archive random library
-lib/libcrypto.a (for architecture x86_64):	current ar archive random library

-This is the big one..
-
-Check it out from svn
-
-cd ~/bitcoin/deps
-svn checkout http://svn.wxwidgets.org/svn/wx/wxWidgets/trunk wxWidgets-trunk
-
-This will make a wxWidgets-trunk directory in deps.
-
-Use this script snippet, change your prefix to whatever your dir is:
-
-PREFIX=~/bitcoin/deps
-SRCDIR="$PREFIX/wxWidgets-trunk"
-BUILDDIR="$SRCDIR/macbuild"

-
-
-
-Now you should be able to build bitcoin
-
-cd ~/bitcoin/trunk
-make -f makefile.osx bitcoin
-
-Before you can run it, you need to create an application bundle for Mac OS.
-Create the directories in terminal using mkdir and copy the files into place.
-They are available at http://heliacal.net/~solar/bitcoin/mac-build/
-You need the Info.plist and the .ins file.  The Contents/MacOS/bitcoin file is
-the output of the build.
-Your directory structure should look like this:
-
-Bitcoin.app
-Bitcoin.app/Contents
-Bitcoin.app/Contents/Info.plist
-Bitcoin.app/Contents/MacOS
-Bitcoin.app/Contents/MacOS/bitcoin
-Bitcoin.app/Contents/Resources
-Bitcoin.app/Contents/Resources/BitcoinAppIcon.icns
-
-To run it you can just click the Bitcoin.app in Finder, or just do open
-~/bitcoin/Bitcoin.app
-If you want to run it with arguments you can just run it without backgrounding
-by specifying the full name in terminal:
-~/bitcoin/Bitcoin.app/Contents/MacOS/bitcoin -addnode=192.75.207.66

+Debian
+====================
+This directory contains files used to package bitcoind/bitcoin-qt
+for Debian-based Linux systems. If you compile bitcoind/bitcoin-qt yourself, there are some useful files here.
+
+## bitcoin: URI support ##
+
+
+bitcoin-qt.desktop  (Gnome / Open Desktop)
+To install:
+
+	sudo desktop-file-install bitcoin-qt.desktop
+	sudo update-desktop-database
+
+If you build yourself, you will either need to modify the paths in
+the .desktop file or copy or symlink your bitcoin-qt binary to `/usr/bin`
+and the `../../share/pixmaps/bitcoin128.png` to `/usr/share/pixmaps`
+
+bitcoin-qt.protocol (KDE)

+##            Quick Primer on addnode vs connect            ##
+##  Let's say for instance you use addnode=4.2.2.4          ##
+##  addnode will connect you to and tell you about the      ##
+##    nodes connected to 4.2.2.4.  In addition it will tell ##
+##    the other nodes connected to it that you exist so     ##
+##    they can connect to you.                              ##
+##  connect will not do the above when you 'connect' to it. ##
+##    It will *only* connect you to 4.2.2.4 and no one else.##
+##                                                          ##
+##  So if you're behind a firewall, or have other problems  ##
+##  finding nodes, add some using 'addnode'.                ##
+##                                                          ##
+##  If you want to stay private, use 'connect' to only      ##
+##  connect to "trusted" nodes.                             ##
+##                                                          ##
+##  If you run multiple nodes on a LAN, there's no need for ##
+##  all of them to open lots of connections.  Instead       ##
+##  'connect' them all to one node that is port forwarded   ##
+##  and has lots of connections.                            ##

+========
+This directory contains tools for developers working on this repository.
+
+clang-format.py
+===============
+
+A script to format cpp source code according to [.clang-format](../../src/.clang-format). This should only be applied to new files or files which are currently not actively developed on. Also, git subtrees are not subject to formatting.
+
+fix-copyright-headers.py
+========================
+
+Every year newly updated files need to have its copyright headers updated to reflect the current year.
+If you run this script from the root folder it will automatically update the year on the copyright header for all
+source files if these have a git commit from the current year.
+
+For example a file changed in 2015 (with 2015 being the current year):
+
+```// Copyright (c) 2009-2013 The Bitcoin Core developers```
+
+would be changed to:
+
+```// Copyright (c) 2009-2015 The Bitcoin Core developers```
+
+git-subtree-check.sh
+====================
+
+Run this script from the root of the repository to verify that a subtree matches the contents of
+the commit it claims to have been updated to.
+
+To use, make sure that you have fetched the upstream repository branch in which the subtree is
+maintained:
+* for `src/secp256k1`: https://github.com/bitcoin/secp256k1.git (branch master)
+* for `src/leveldb`: https://github.com/bitcoin/leveldb.git (branch bitcoin-fork)
+* for `src/univalue`: https://github.com/bitcoin/univalue.git (branch master)
+
+Usage: `git-subtree-check.sh DIR COMMIT`
+
+`COMMIT` may be omitted, in which case `HEAD` is used.
+
+github-merge.sh
+===============
+
+A small script to automate merging pull-requests securely and sign them with GPG.
+
+For example:
+
+  ./github-merge.sh bitcoin/bitcoin 3077
+
+(in any git repository) will help you merge pull request #3077 for the
+bitcoin/bitcoin repository.
+
+What it does:
+* Fetch master and the pull request.
+* Locally construct a merge commit.
+* Show the diff that merge results in.
+* Ask you to verify the resulting source tree (so you can do a make
+check or whatever).
+* Ask you whether to GPG sign the merge commit.
+* Ask you whether to push the result upstream.
+
+This means that there are no potential race conditions (where a
+pullreq gets updated while you're reviewing it, but before you click
+merge), and when using GPG signatures, that even a compromised github
+couldn't mess with the sources.
+
+Setup
+---------
+Configuring the github-merge tool for the bitcoin repository is done in the following way:
+
+    git config githubmerge.repository bitcoin/bitcoin
+    git config githubmerge.testcmd "make -j4 check" (adapt to whatever you want to use for testing)
+    git config --global user.signingkey mykeyid (if you want to GPG sign)
+
+optimize-pngs.py
+================
+
+A script to optimize png files in the bitcoin
+repository (requires pngcrush).
+
+security-check.py and test-security-check.py
+============================================
+
+Perform basic ELF security checks on a series of executables.
+
+symbol-check.py
+===============
+
+A script to check that the (Linux) executables produced by gitian only contain
+allowed gcc, glibc and libstdc++ version symbols. This makes sure they are
+still compatible with the minimum supported Linux distribution versions.
+
+Example usage after a gitian build:
+
+    find ../gitian-builder/build -type f -executable | xargs python contrib/devtools/symbol-check.py 
+
+If only supported symbols are used the return value will be 0 and the output will be empty.
+
+If there are 'unsupported' symbols, the return value will be 1 a list like this will be printed:
+
+    .../64/test_bitcoin: symbol memcpy from unsupported version GLIBC_2.14
+    .../64/test_bitcoin: symbol __fdelt_chk from unsupported version GLIBC_2.15
+    .../64/test_bitcoin: symbol std::out_of_range::~out_of_range() from unsupported version GLIBCXX_3.4.15
+    .../64/test_bitcoin: symbol _ZNSt8__detail15_List_nod from unsupported version GLIBCXX_3.4.15
+
+update-translations.py
+======================
+
+Run this script from the root of the repository to update all translations from transifex.
+It will do the following automatically:
+
+- fetch all translations
+- post-process them into valid and committable format
+- add missing translations to the build system (TODO)
+
+See doc/translation-process.md for more information.

+### Gavin's notes on getting gitian builds up and running using KVM
+
+These instructions distilled from
+[https://help.ubuntu.com/community/KVM/Installation](https://help.ubuntu.com/community/KVM/Installation).
+
+You need the right hardware: you need a 64-bit-capable CPU with hardware virtualization support (Intel VT-x or AMD-V). Not all modern CPUs support hardware virtualization.
+
+You probably need to enable hardware virtualization in your machine's BIOS.
+
+You need to be running a recent version of 64-bit-Ubuntu, and you need to install several prerequisites:
+
+	sudo apt-get install ruby apache2 git apt-cacher-ng python-vm-builder qemu-kvm
+
+Sanity checks:
+
+	sudo service apt-cacher-ng status  # Should return apt-cacher-ng is running
+	ls -l /dev/kvm   # Should show a /dev/kvm device
+
+
+Once you've got the right hardware and software:
+
+    git clone git://github.com/bitcoin/bitcoin.git
+    git clone git://github.com/devrandom/gitian-builder.git
+    mkdir gitian-builder/inputs
+    cd gitian-builder/inputs
+
+    # Create base images
+    cd gitian-builder
+    bin/make-base-vm --suite trusty --arch amd64
+    cd ..
+
+    # Get inputs (see doc/release-process.md for exact inputs needed and where to get them)
+    ...
+
+    # For further build instructions see doc/release-process.md
+    ...
+
+---------------------
+
+`gitian-builder` now also supports building using LXC. See
+[help.ubuntu.com](https://help.ubuntu.com/14.04/serverguide/lxc.html)
+for how to get LXC up and running under Ubuntu.
+
+If your main machine is a 64-bit Mac or PC with a few gigabytes of memory
+and at least 10 gigabytes of free disk space, you can `gitian-build` using
+LXC running inside a virtual machine.
+
+Here's a description of Gavin's setup on OSX 10.6:
+
+1. Download and install VirtualBox from [https://www.virtualbox.org/](https://www.virtualbox.org/)
+
+2. Download the 64-bit Ubuntu Desktop 12.04 LTS .iso CD image from
+   [http://www.ubuntu.com/](http://www.ubuntu.com/)
+
+3. Run VirtualBox and create a new virtual machine, using the Ubuntu .iso (see the [VirtualBox documentation](https://www.virtualbox.org/wiki/Documentation) for details). Create it with at least 2 gigabytes of memory and a disk that is at least 20 gigabytes big.
+
+4. Inside the running Ubuntu desktop, install:
+
+	sudo apt-get install debootstrap lxc ruby apache2 git apt-cacher-ng python-vm-builder
+
+5. Still inside Ubuntu, tell gitian-builder to use LXC, then follow the "Once you've got the right hardware and software" instructions above:
+
+	export USE_LXC=1
+	git clone git://github.com/bitcoin/bitcoin.git
+	... etc
