+# Contribute guidelines
+
+We are always looking for people to help improve Impostor.
+
+## Code
+
+- If you are implementing or fixing an issue, please comment on the issue so work is not duplicated.
+- If you want to implementing a new feature, create an issue first describing the issue so we know about it. We are always open for discussion or questions on [Discord](https://discord.gg/Mk3w6Tb).
+- Don't commit unnecessary changes to the codebase or debugging code.
+- Write meaningful commits or squash them.
+- Please try to follow the code style of the rest of the codebase. An `.editorconfig` file has been provided to keep consistency.
+
+## Pull requests
+
+- Only make pull requests to the `dev` branch.
+- Only implement one feature per pull request to keep it easy to understand.
+- Expect comments or questions on your pull request from the project maintainers. We try to keep the code as consistent and maintainable as possible.
+- Each pull request should come from a new branch in your fork, it should have a meaningful name. 
+- We try to respond to pull requests as fast as possible. If you think we might have missed it, let us know on [Discord](https://discord.gg/Mk3w6Tb).
+
+
+If you have any questions, let us know.
