+"""
+Hi!
+
+Thank you for your interest in working on this LLVM issue.
+As your first steps...
+
+  1) Clone the git repository.
+  2) Fix the issue locally.
+  3) [Run the test suite](https://llvm.org/docs/TestingGuide.html#unit-and-regression-tests) locally.
+    3.1) Remember that the subdirectories under `test/` create fine-grained testing target, so you can
+         e.g. use `make check-clang-ast` to only run Clang's AST tests.
+  4) Create a `git` commit
+  5) Run `git clang-format HEAD~1` to format your changes.
+  6) Submit the patch to [Phabricator](https://reviews.llvm.org/).
+    6.1) Don't forget to upload your patch with sufficient context, e.g. `git show HEAD -U99990`.
+
+For more instructions on how to submit a patch to LLVM, see our [documentation](https://llvm.org/docs/Contributing.html).
+
+If you have any further questions about this issue, don't hesitate to ask via a comment on this Github issue.
