+# Development
+
+## Set up
+
+```shell
+python3 -m venv --clear venv
+source venv/bin/activate
+poetry self add "poetry-dynamic-versioning[plugin]"
+poetry install
+pre-commit install
+```
+
+## Testing
+
+
+To run tests fast:
+```shell
+pytest -n auto tests
+```
+
+To Get coverage:
+```shell
+coverage run --branch --include "./beavers/*" -m pytest tests
+coverage report --show-missing
+```
+
+## Generating the change log
+
+We use [git-change-log](https://pawamoy.github.io/git-changelog/usage/) to generate our CHANGELOG.md
+
+Please follow the [basic convention](https://pawamoy.github.io/git-changelog/usage/#basic-convention) for  commit message.
+
+To update the change log, run:
+```shell
+git-changelog -io CHANGELOG.md
+```
+
+## New Release
+
+For new release, first prepare the change log, push and merge it.
+```shell
+git-changelog -bio CHANGELOG.md``
+```
+
+Then tag and push:
+```shell
+git tag vX.X.X
+git push origin vX.X.X
+```
+
+Lastly on github, go to tags and create a release. 
+The CI will deploy to pypi automatically from then.
+
+## Testing the documentation
+
+```shell
+mkdocs serve --livereload --watch=./
+```
+
+## Updating dependencies
+
+- For the repo `poetry lock`
+- For the doc: `(cd docs/; pip-compile ./requirements.in  > ./requirements.txt)`
+
+## Resources
+
+The repo set up is inspired by this [guide](https://mathspp.com/blog/how-to-create-a-python-package-in-2022)
