-### 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.
