+When preparing a patch, it's recommended that you add unit tests

+You can run the tests on your local machine by installing the `dev` extras.
+The steps below do this using a virtual environment:
+
+```shell
+# Create a local virtual environment
+$ python -m venv .venv
+
+# Activate the virtual environment
+# Cygwin, Linux, and MacOS:
+$ . .venv/bin/activate
+# Windows Powershell:
+$ & .venv\Scripts\Activate.ps1
+
+# Update pip and setuptools
+(.venv) $ python -m pip install -U pip setuptools
+
+# Install dotbot and its development dependencies
+(.venv) $ python -m pip install -e .[dev]

-Testing
-=======
-
-Dotbot testing code uses [Vagrant] to run all tests inside a virtual machine to
-have tests be completely isolated from the host machine.  Specifically, you
-will need both:
-
-  - [VirtualBox]
-  - [Vagrant]
-
-Install Dotbot dependencies
----------------------------
-
-Ensure you have updated the `dotbot` submodule dependencies, on the host machine:
-
-```bash
-git submodule sync --quiet --recursive
-git submodule update --init --recursive
-```
-Install Vagrant
----------------
-
-### Debian-based distributions
-
-```bash
-sudo apt install vagrant virtualbox
-```
-
-### macOS
-
-You can download those directly from the above URLs, or via some MacOS package managers.
-e.g. using [HomeBrew](https://brew.sh/):
-
-```bash
-brew cask install virtualbox
-brew cask install vagrant
-# optional, adding menu-bar support:
-brew cask install vagrant-manager
-```
-
-Running the Tests
------------------
-
-Before running the tests, you must start and `ssh` into the VM:
-
-```bash
-vagrant up
-vagrant ssh
-```
-
-All remaining commands are run inside the VM.
-
-First, you must install a version of Python to test against, using:
-
-    pyenv install -s {version}
-
-You can choose any version you like, e.g. `3.8.1`. It isn't particularly
-important to test against all supported versions of Python in the VM, because
-they will be tested by CI. Once you've installed a specific version of Python,
-activate it with:
-
-    pyenv global {version}
-
-The VM mounts your host's Dotbot directory in `/dotbot` as read-only, allowing
-you to make edits on your host machine.  Run the entire test suite by:
-
-```bash
-cd /dotbot/test
-./test
-```
-
-Selected tests can be run by passing paths to the tests as arguments, e.g.:
-
-```bash
-./test tests/create.bash tests/defaults.bash
-```
-
-To debug tests, you can run the test driver with the `--debug` (or `-d` short
-form) flag, e.g. `./test --debug tests/link-if.bash`. This will enable printing
-stdout/stderr.
-
-When finished with testing, it is good to shut down the virtual machine by
-running `vagrant halt`.
