 ## Quick Install
 
+Versioneer provides two installation modes. The "classic" vendored mode installs
+a copy of versioneer into your repository. The experimental build-time dependency mode
+is intended to allow you to skip this step and simplify the process of upgrading.
+
+### Vendored mode
+
+* `pip install versioneer` to somewhere in your $PATH
+   * A [conda-forge recipe](https://github.com/conda-forge/versioneer-feedstock) is
+     available, so you can also use `conda install -c conda-forge versioneer`
+* add a `[tool.versioneer]` section to your `pyproject.toml` or a
+  `[versioneer]` section to your `setup.cfg` (see [Install](INSTALL.md))
+   * Note that you will need to add `tomli; python_version < "3.11"` to your
+     build-time dependencies if you use `pyproject.toml`
+* run `versioneer install --vendor` in your source tree, commit the results
+* verify version information with `python setup.py version`
