+To clone the [the GitHub repository](https://github.com/gitpython-developers/GitPython) from source to work on the code, you can do it like so:
 
 ```bash
 git clone https://github.com/gitpython-developers/GitPython
-git submodule update --init --recursive
+cd GitPython
+git fetch --tags
 ./init-tests-after-clone.sh
 ```
 
+If you are cloning [your own fork](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/about-forks), then replace the above `git clone` command with one that gives the URL of your fork. Or use this [`gh`](https://cli.github.com/) command (assuming you have `gh` and your fork is called `GitPython`):
+
+```bash
+gh repo clone GitPython
+```
+
+Having cloned the repo, create and activate your [virtual environment](https://docs.python.org/3/tutorial/venv.html). Then make an [editable install](https://pip.pypa.io/en/stable/topics/local-project-installs/#editable-installs):
+
+```bash
+pip install -e ".[test]"
+```
+
+In the less common case that you do not want to install test dependencies, `pip install -e .` can be used instead.

 ### How to make a new release
 
-- Update/verify the **version** in the `VERSION` file
-- Update/verify that the `doc/source/changes.rst` changelog file was updated
-- Commit everything
-- Run `git tag -s <version>` to tag the version in Git
-- Run `make release`
+- Update/verify the **version** in the `VERSION` file.
+- Update/verify that the `doc/source/changes.rst` changelog file was updated.
+- Commit everything.
+- Run `git tag -s <version>` to tag the version in Git.
+- _Optionally_ create and activate a [virtual environment](https://packaging.python.org/en/latest/guides/installing-using-pip-and-virtual-environments/#creating-a-virtual-environment) using `venv` or `virtualenv`.\
+(When run in a virtual environment, the next step will automatically take care of installing `build` and `twine` in it.)
+- Run `make release`.
 - Close the milestone mentioned in the _changelog_ and create a new one. _Do not reuse milestones by renaming them_.
-- Got to [GitHub Releases](https://github.com/gitpython-developers/GitPython/releases) and publish a new one with the recently pushed tag. Generate the changelog.
