 the old version of Dotbot will be checked out by the install script. If using a
 subrepo, run `git fetch && git checkout origin/master` in the Dotbot directory.
 
+If you prefer, you can install Dotbot from [PyPI] and call it as a command-line
+program:
+
+```bash
+pip install dotbot
+touch install.conf.yaml
+```
+
+In this case, rather than running `./install`, you can invoke Dotbot with
+`dotbot -c <path to configuration file>`.
