+# Contributing to GPT Engineer
+
+By participating in this project, you agree to abide by the [code of conduct](CODE_OF_CONDUCT.md).
+
+## Getting Started
+
+To get started with contributing, please follow these steps:
+
+1. Fork the repository and clone it to your local machine.
+2. Install any necessary dependencies.
+3. Create a new branch for your changes: `git checkout -b my-branch-name`.
+4. Make your desired changes or additions.
+5. Run the tests to ensure everything is working as expected.
+6. Commit your changes: `git commit -m "Descriptive commit message"`.
+7. Push to the branch: `git push origin my-branch-name`.
+8. Submit a pull request to the `main` branch of the original repository.
+
+
+## Code Style
+
+Please make sure to follow the established code style guidelines for this project. Consistent code style helps maintain readability and makes it easier for others to contribute to the project.
+
+To enforce this we use [`pre-commit`](https://pre-commit.com/) to run [`black`](https://black.readthedocs.io/en/stable/index.html) and [`ruff`](https://beta.ruff.rs/docs/) on every commit.
+
+`pre-commit` is part of our `requirements.txt` file so you should already have it installed. If you don't, you can install the library via pip with:
+
+```bash
+$ pip install -r requirements.txt
+```
+
+And then install the `pre-commit` hooks with:
+```bash
+$ pre-commit install
+
+pre-commit installed at .git/hooks/pre-commit
+
+```
+
+If you are not familiar with the concept of [git hooks](https://git-scm.com/docs/githooks) and/or [`pre-commit`](https://pre-commit.com/) please read the documentation to understand how they work.
+
+As an introduction of the actual workflow, here is an example of the process you will encounter when you make a commit:
+
+Let's add a file we have modified with some errors, see how the pre-commit hooks run `black` and fails.
+`black` is set to automatically fix the issues it finds:
+```bash
+$ git add chat_to_files.py
+$ git commit -m "commit message"
+black....................................................................Failed
+- hook id: black
+- files were modified by this hook
+
+reformatted chat_to_files.py
+
+All done! ✨ 🍰 ✨
+1 file reformatted.
+```
+
+You can see that `chat_to_files.py` is both staged and not staged for commit. This is because `black` has formatted it and now it is different from the version you have in your working directory. To fix this you can simply run `git add chat_to_files.py` again and now you can commit your changes.
+```bash
+$ git status
+On branch pre-commit-setup
+Changes to be committed:
+  (use "git restore --staged <file>..." to unstage)
+    modified:   chat_to_files.py
+
+Changes not staged for commit:
+  (use "git add <file>..." to update what will be committed)
+  (use "git restore <file>..." to discard changes in working directory)
+    modified:   chat_to_files.py
+```
+
+
+Now let's add the file again to include the latest commits and see how `ruff` fails.
+```bash
+$ git add chat_to_files.py
+$ git commit -m "commit message"
+black....................................................................Passed
+ruff.....................................................................Failed
+- hook id: ruff
+- exit code: 1
+- files were modified by this hook
+
+Found 2 errors (2 fixed, 0 remaining).
+```
+
+Same as before, you can see that `chat_to_files.py` is both staged and not staged for commit. This is because `ruff` has formatted it and now it is different from the version you have in your working directory. To fix this you can simply run `git add chat_to_files.py` again and now you can commit your changes.
+```bash
+$ git add chat_to_files.py
+$ git commit -m "commit message"
+black....................................................................Passed
+ruff.....................................................................Passed
+fix end of files.........................................................Passed
+[pre-commit-setup f00c0ce] testing
+ 1 file changed, 1 insertion(+), 1 deletion(-)
+```
+
+Now your file has been committed and you can push your changes.
+
+At the beggining this might seem like a tedious process (having to add the file again after `black` and `ruff` have modified it) but it is actually very useful. It allows you to see what changes `black` and `ruff` have made to your files and make sure that they are correct before you commit them.
+
+
+
