+## Configure CMake and Build
+
+To configure cmake, run `cmake --preset default --fresh`.
+To build, run `cmake --workflow --preset debug` or `cmake --workflow --preset release`.
+
+## Formatting
+
+Your PR needs to be formatted according to our coding style.
+Run `./extras/formatting.sh` script to format your changes before creating a PR.
+
+## Labeling your PR
+
+All PRs needs to be labeled as either "pr: non-breaking" or "pr: breaking".
+Label your PR as "pr: breaking" if you are introducing public API changes that breaks ABI compabibility,
+or you are introducing changes to the Slang language that will cause the compiler to error out on existing Slang code.
+It is rare for a PR to be a breaking change.
+
+## Testing
+
+Your PR should include a regression test for the bug you are fixing.
+Normally, these tests present as a `.slang` file under `tests/` directory.
+You will need to run your test with `slang-test tests/path/to/your-new-test.slang`.
