+# How to contribute
+
+## Dependencies
+
+We use [poetry](https://github.com/python-poetry/poetry) to manage the dependencies.
+
+To install them you would need to run `install` command:
+
+```bash
+poetry install
+```
+
+To activate your `virtualenv` run `poetry shell`.
+
+## Style checks
+
+We use `pre-commit` for quality control.
+
+To run checks:
+
+```bash
+inv pre-commit.run-hooks
+```
+
+Note: we also have flake8 dependencies for proper support of flake8 vscode
+plugin.
+
+## Submitting your code
+
+We use [trunk based](https://trunkbaseddevelopment.com/) development.
+
+What the point of this method?
+
+1. We use protected `main` branch,
+   so the only way to push your code is via pull request
+2. We use issue branches: to implement a new feature or to fix a bug
+   create a new branch named `issue-$TASKNUMBER`
+3. Then create a pull request to `main` branch
+4. We use `git tag`s to make releases, so we can track what has changed
+   since the latest release
+
+So, this way we achieve an easy and scalable development process
+which frees us from merging hell and long-living branches.
+
+In this method, the latest version of the app is always in the `main` branch.
+
+### Before submitting
+
+Before submitting your code please do the following steps:
+
+1. Add any changes you want
+2. Edit documentation if you have changed something significant
+3. Update `CHANGELOG.md` with a quick summary of your changes
+4. Run `pre-commit` to ensure that style is correct
