+# How to contribute to the AI Horde code
+
+We are happy you have ideas to improve this service and we welcome all contributors.
+
+Once you have an idea you want to work on, we suggest you first open a [feature request](https://github.com/orgs/Haidra-Org/projects/14) as the AI Horde has a lot of moving pieces in multiple components which might need to be adjusted, such as the AI Horde API, the reGen worker or the horde-engine library.
+
+Our codebase makes use of multiple tools to keep our work standardized. We typically use [pre-commit](https://pre-commit.com/) to ensure that all linting and code checking is performed.
+
+You can install all the dev tools we're using by using `requirements.dev.txt` and then the pre-commit hook
+
+```bash
+python -m pip install -r requirements.dev.txt
+pre-commit install
+```
+
+This will ensure that the project will prevent you from commiting changes which will not pass our CI checks.
+
+The tools we're using are the following
+
+## black
+
+To format all files as necessary, simply run:
+
+```bash
+black .
+```
+
+## ruff
+
+To adjust all files as necessary, simply run:
+
+
+```bash
+ruff . --fix
+```
+
+Ruff might request extra manual fixes
+
+## reuse
+
+[Reuse](https://reuse.software/) ensures that all license and contribution info is maintained. You usually don't need to do anything about this unless you add a new file, or you make significant changes in an existing one.
+
+
+### New file
+
+If you add a new file, you need to ensure that it has the copyright and license information with a command like this
+
+```bash
+reuse annotate  --copyright db0 --license="AGPL-3.0-or-later"  horde/my_new_code.py
+```
+
+Simply replace the copyright with your own username and optionally email.
+
+The license to choose is based on the file.
+
+* For normal code contributions, use `AGPL-3.0-or-later`
+* For non-GenAI art and other such creative contributions, use `CC-BY-SA-4.0`
+* For trivial files such as .gitignore and Generative AI art, use `CC0-1.0`
+
+### Existing file
+
+If you did some significant contributions to the code (i.e. not things like syntax, spelling. linting etc), then just add your own copyrights to an existing file
+
+```bash
+reuse annotate  --copyright db0 horde/existing_code.py
+```
+
+Simply replace the copyright with your own username and optionally email.
