-Getting Started
----------------
-
-New contributors are very welcome and needed.
-
-Reviewing and testing is highly valued and the most effective way you can contribute
-as a new contributor. It also will teach you much more about the code and
-process than opening pull requests. Please refer to the [peer review](#peer-review)
-section below.
-
-Before you start contributing, familiarize yourself with the Bitcoin Core build
-system and tests. Refer to the documentation in the repository on how to build
-Bitcoin Core and how to run the unit tests, functional tests, and fuzz tests.
-
-There are many open issues of varying difficulty waiting to be fixed.
 If you're looking for somewhere to start contributing, check out the

-
-### Good First Issue Label
-
-The purpose of the `good first issue` label is to highlight which issues are
-suitable for a new contributor without a deep understanding of the codebase.
-
-However, good first issues can be solved by anyone. If they remain unsolved
-for a longer time, a frequent contributor might address them.
-
-You do not need to request permission to start working on an issue. However,
-you are encouraged to leave a comment if you are planning to work on it. This
-will help other contributors monitor which issues are actively being addressed
-and is also an effective way to request assistance if and when you need it.

 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:
 
-  1. Fork repository ([only for the first time](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/fork-a-repo))
+  1. Fork repository
   1. Create topic branch
   1. Commit patches
 
-For GUI-related issues or pull requests, the https://github.com/bitcoin-core/gui repository should be used.
-For all other issues and pull requests, the https://github.com/bitcoin/bitcoin node repository should be used.
-
-The master branch for all monotree repositories is identical.
-
-As a rule of thumb, everything that only modifies `src/qt` is a GUI-only pull
-request. However:
-
-* For global refactoring or other transversal changes the node repository
-  should be used.
-* For GUI-related build system changes, the node repository should be used
-  because the change needs review by the build systems reviewers.
-* Changes in `src/interfaces` need to go to the node repository because they
-  might affect other components like the wallet.
-
-For large GUI changes that include build system and interface changes, it is
-recommended to first open a pull request against the GUI repository. When there
-is agreement to proceed with the changes, a pull request with the build system
-and interfaces changes can be submitted to the node repository.

-After a rebase, reviewers are encouraged to sign off on the force push. This should be relatively straightforward with

+# SYNOPSIS
+#
+#   AX_BOOST_UNIT_TEST_FRAMEWORK
+#
+# DESCRIPTION
+#
+#   Test for Unit_Test_Framework library from the Boost C++ libraries. The
+#   macro requires a preceding call to AX_BOOST_BASE. Further documentation
+#   is available at <http://randspringer.de/boost/index.html>.
+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_UNIT_TEST_FRAMEWORK_LIB)
+#
+#   And sets:
+#
+#     HAVE_BOOST_UNIT_TEST_FRAMEWORK

+# 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
+#    constructor_priority for constructor attribute with priority
+#    deprecated
+#    destructor
+#    dllexport
+#    dllimport
+#    error
+#    externally_visible
+#    flatten
+#    format
+#    format_arg
+#    gnu_inline
+#    hot
+#    ifunc
+#    leaf
+#    malloc
+#    noclone
+#    noinline
+#    nonnull
+#    noreturn
+#    nothrow
+#    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 to link with them as well. For example, you might link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threaded programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, this macro 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.

+Building Bitcoin Core with Visual Studio
+========================================
+
+Introduction
+---------------------
+Solution and project files to build the Bitcoin Core applications `msbuild` or Visual Studio can be found in the build_msvc directory. The build has been tested with Visual Studio 2017 and 2019.
+
+Building with Visual Studio is an alternative to the Linux based [cross-compiler build](https://github.com/bitcoin/bitcoin/blob/master/doc/build-windows.md).
+
+Quick Start
+---------------------
+The minimal steps required to build Bitcoin Core with the msbuild toolchain are below. More detailed instructions are contained in the following sections.
+
+```
+vcpkg install --triplet x64-windows-static boost-filesystem boost-signals2 boost-test libevent openssl zeromq berkeleydb rapidcheck double-conversion
+py -3 build_msvc\msvc-autogen.py
+msbuild /m build_msvc\bitcoin.sln /p:Platform=x64 /p:Configuration=Release /t:build
+```
+
+Dependencies
+---------------------
+A number of [open source libraries](https://github.com/bitcoin/bitcoin/blob/master/doc/dependencies.md) are required in order to be able to build Bitcoin Core.
+
+Options for installing the dependencies in a Visual Studio compatible manner are:
+
+- Use Microsoft's [vcpkg](https://docs.microsoft.com/en-us/cpp/vcpkg) to download the source packages and build locally. This is the recommended approach.
+- Download the source code, build each dependency, add the required include paths, link libraries and binary tools to the Visual Studio project files.
+- Use [nuget](https://www.nuget.org/) packages with the understanding that any binary files have been compiled by an untrusted third party.
+
+The [external dependencies](https://github.com/bitcoin/bitcoin/blob/master/doc/dependencies.md) required for building are:
+
+- Berkeley DB
+- Boost
+- DoubleConversion
+- libevent
+- OpenSSL
+- Qt5
+- RapidCheck
+- ZeroMQ
+
+Qt
+---------------------
+All the Bitcoin Core applications are configured to build with static linking. In order to build the Bitcoin Core Qt applications a static build of Qt is required.
+
+The runtime library version (e.g. v141, v142) and platform type (x86 or x64) must also match. OpenSSL must also be linked into the Qt binaries in order to provide full functionality of the Bitcoin Core Qt programs. An example of the configure command to build Qtv5.9.7 locally to link with Bitcoin Core is shown below (adjust paths accordingly), note it can be expected that the configure and subsequent build will fail numerous times until dependency issues are resolved.
+
+````

+````
+
+A prebuilt version for x64 and Visual C++ runtime v141 (Visual Studio 2017) can be downloaded from [here](https://github.com/sipsorcery/qt_win_binary/releases). Please be aware this download is NOT an officially sanctioned Bitcoin Core distribution and is provided for developer convenience. It should NOT be used for builds that will be used in a production environment or with real funds.
+
+To build Bitcoin Core without Qt unload or disable the bitcoin-qt, libbitcoin_qt and test_bitcoin-qt projects.
+
+Building
+---------------------
+The instructions below use `vcpkg` to install the dependencies.
+
+- Clone `vcpkg` from the [github repository](https://github.com/Microsoft/vcpkg) and install as per the instructions in the main README.md.
+- Install the required packages (replace x64 with x86 as required):
+
+```
+    PS >.\vcpkg install --triplet x64-windows-static boost-filesystem boost-signals2 boost-test libevent openssl zeromq berkeleydb rapidcheck double-conversion
+```
+
+- Use Python to generate *.vcxproj from Makefile
+
+```
+    PS >py -3 msvc-autogen.py
+```
+
+- An optional step is to adjust the settings in the build_msvc directory and the common.init.vcxproj file. This project file contains settings that are common to all projects such as the runtime library version and target Windows SDK version. The Qt directories can also be set.
+
+- Build with Visual Studio 2017 or msbuild.
+
+```
+msbuild /m bitcoin.sln /p:Platform=x64 /p:Configuration=Release /t:build
+```
+
+- Build with Visual Studio 2019 or msbuild.
+
+```
+msbuild /m bitcoin.sln /p:Platform=x64 /p:Configuration=Release /p:PlatformToolset=v142 /t:build
+```
+
+AppVeyor
+---------------------
+The .appveyor.yml in the root directory is suitable to perform builds on [AppVeyor](https://www.appveyor.com/) Continuous Integration servers. The simplest way to perform an AppVeyor build is to fork Bitcoin Core and then configure a new AppVeyor Project pointing to the forked repository.
+
+For safety reasons the Bitcoin Core .appveyor.yml file has the artifact options disabled. The build will be performed but no executable files will be available. To enable artifacts on a forked repository uncomment the lines shown below:
+
+```
+    #- 7z a bitcoin-%APPVEYOR_BUILD_VERSION%.zip %APPVEYOR_BUILD_FOLDER%\build_msvc\%platform%\%configuration%\*.exe
+    #- path: bitcoin-%APPVEYOR_BUILD_VERSION%.zip
+```

-# CI Scripts
+## ci scripts
 
 This directory contains scripts for each build step in each build stage.
 
-## Running a Stage Locally
+Currently three stages `lint`, `extended_lint` and `test` are defined. Each stage has its own lifecycle, similar to the
+[Travis CI lifecycle](https://docs.travis-ci.com/user/job-lifecycle#the-job-lifecycle). Every script in here is named
+and numbered according to which stage and lifecycle step it belongs to.
 
-Be aware that the tests will be built and run in-place, so please run at your own risk.
-If the repository is not a fresh git clone, you might have to clean files from previous builds or test runs first.
-
-The ci needs to perform various sysadmin tasks such as installing packages or writing to the user's home directory.
-While it should be fine to run
-the ci system locally on your development box, the ci scripts can generally be assumed to have received less review and
-testing compared to other parts of the codebase. If you want to keep the work tree clean, you might want to run the ci
-system in a virtual machine with a Linux operating system of your choice.
+### Running a stage locally
 
 To allow for a wide range of tested environments, but also ensure reproducibility to some extent, the test stage
-requires `bash`, `docker`, and `python3` to be installed. To run on different architectures than the host `qemu` is also required. To install all requirements on Ubuntu, run
+requires `docker` to be installed. To install all requirements on Ubuntu, run
 
 ```
-sudo apt install bash docker.io python3 qemu-user-static
+sudo apt install docker.io ccache bash git
 ```
 
-For some sanitizer builds, the kernel's address-space layout randomization
-(ASLR) entropy can cause sanitizer shadow memory mappings to fail. When running
-the CI locally you may need to reduce that entropy by running:
+To run the default test stage,
 
 ```
-sudo sysctl -w vm.mmap_rnd_bits=28
+./ci/test_run_all.sh
 ```
 
-To run a test that requires emulating a CPU architecture different from the
-host, we may rely on the container environment recognizing foreign executables
-and automatically running them using `qemu`. The following sets us up to do so
-(also works for `podman`):
+To run the test stage with a specific configuration,
 
 ```
-docker run --rm --privileged docker.io/multiarch/qemu-user-static --reset -p yes
+FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh
 ```
 
-It is recommended to run the CI system in a clean environment. The `env -i`
-command below ensures that *only* specified environment variables are propagated
-into the local CI.
-To run the test stage with a specific configuration:
-
-```
-env -i HOME="$HOME" PATH="$PATH" USER="$USER" FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh
-```
-
-## Configurations
-
-The test files (`FILE_ENV`) are constructed to test a wide range of
-configurations, rather than a single pass/fail. This helps to catch build
-failures and logic errors that present on platforms other than the ones the
-author has tested.
-
-Some builders use the dependency-generator in `./depends`, rather than using
-the system package manager to install build dependencies. This guarantees that
-the tester is using the same versions as the release builds, which also use
-`./depends`.
-
-It is also possible to force a specific configuration without modifying the
-file. For example,
-
-```
-env -i HOME="$HOME" PATH="$PATH" USER="$USER" MAKEJOBS="-j1" FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh
-```
-
-The files starting with `0n` (`n` greater than 0) are the scripts that are run
-in order.
-
-## Cache
-
-In order to avoid rebuilding all dependencies for each build, the binaries are
-cached and reused when possible. Changes in the dependency-generator will
-trigger cache-invalidation and rebuilds as necessary.
-
-## Configuring a repository for CI
-
-### Primary repository
-
-To configure the primary repository, follow these steps:
-
-1. Register with [Cirrus Runners](https://cirrus-runners.app/) and purchase runners.
-2. Install the Cirrus Runners GitHub app against the GitHub organization.
-3. Enable organisation-level runners to be used in public repositories:
-   1. `Org settings -> Actions -> Runner Groups -> Default -> Allow public repos`
-4. Permit the following actions to run:
-   1. cirruslabs/cache/restore@\*
-   1. cirruslabs/cache/save@\*
-   1. docker/setup-buildx-action@\*
-   1. actions/github-script@\*
-
-### Forked repositories
-
-When used in a fork the CI will run on GitHub's free hosted runners by default.
-In this case, due to GitHub's 10GB-per-repo cache size limitations caches will be frequently evicted and missed, but the workflows will run (slowly).

-It is also possible to use your own Cirrus Runners in your own fork with an appropriate patch to the `REPO_USE_CIRRUS_RUNNERS` variable in ../.github/workflows/ci.yml
-NB that Cirrus Runners only work at an organisation level, therefore in order to use your own Cirrus Runners, *the fork must be within your own organisation*.
+Be aware that the tests will be build and run in-place, so please run at your own risk.
+If the repository is not a fresh git clone, you might have to clean files from previous builds or test runs first.
