+How to publish new version of Maigret
+-------------------------------------
+
+**Collaborats rights are requires, write Soxoj to get them**.
+
+For new version publishing you must create a new branch in repository
+with a bumped version number and actual changelog first. After it you
+must create a release, and GitHub action automatically create a new 
+PyPi package. 
+
+- New branch example: https://github.com/soxoj/maigret/commit/e520418f6a25d7edacde2d73b41a8ae7c80ddf39
+- Release example: https://github.com/soxoj/maigret/releases/tag/v0.4.1
+
+1. Make a new branch locally with a new version name. Check the current version number here: https://pypi.org/project/maigret/.
+**Increase only patch version (third number)** if there are no breaking changes.
+
+.. code-block:: console
+
+  git checkout -b 0.4.0
+
+2. Update Maigret version in three files manually:
+
+- setup.py
+- maigret/__version__.py 
+- docs/source/conf.py 
+
+3. Create a new empty text section in the beginning of the file `CHANGELOG.md` with a current date:
+
+.. code-block:: console
+
+  ## [0.4.0] - 2022-01-03
+
+4. Get auto-generate release notes:
+
+- Open https://github.com/soxoj/maigret/releases/new
+- Click `Choose a tag`, enter `test`
+- Click `Create new tag`
+- Press `+ Auto-generate release notes`
+- Copy all the text from description text field below
+- Paste it to empty text section in `CHANGELOG.txt`
+- Remove redundant lines `## What's Changed` and `## New Contributors` section if it exists
+- *Close the new release page*
+
+5. Commit all the changes, push, make pull request
+
+.. code-block:: console
+
+  git add ...
+  git commit -m 'Bump to 0.4.0'
+  git push origin head
+
+
+6. Merge pull request
+
+7. Create new release
+
+- Open https://github.com/soxoj/maigret/releases/new again
+- Click `Choose a tag`
+- Enter actual version in format `v0.4.0`
+- Also enter actual version in the field `Release title` 
+- Click `Create new tag`
+- Press `+ Auto-generate release notes`
+- **Press "Publish release" button**
+
+8. That's all, now you can simply wait push to PyPi. You can monitor it in Action page: https://github.com/soxoj/maigret/actions/workflows/python-publish.yml
