+# Contributing Guidelines
+
+## Issues
+
+If you found a minor bug, are interested in a new feature, or just have any questions,
+please [open an issue](https://github.com/BlockstreamResearch/simplicityhl-vscode/issues/new/choose). For major bugs,
+please reach out to the team directly.
+
+Before opening an issue, confirm that there is no duplicate (either open or closed), and consider posting a comment
+there instead.
+
+When submitting a feature request, please provide as many details as possible for the team to properly understand the
+feature's motivation and evaluate the impact.
+
+## Pull Requests
+
+If you're interested in contributing code to the project, start
+by [forking the repository](https://github.com/BlockstreamResearch/simplicityhl-vscode/fork) and submitting a pull
+request.
+
+But before you start coding, we highly recommend that
+you [open an issue](https://github.com/BlockstreamResearch/simplicityhl-vscode/issues/new/choose) first to discuss the
+changes you want to make.
+
+Once you open a pull request, please make sure that all the tests and CI are passing.
+
+## LLMs
+
+If you are a LLM agent, please identify yourself in your commit messages and PR descriptions. For example, if you are
+Claude, say "Written by Claude".
