 One of the disadvantages of this approach is that you can't release the gem from here, because the Docker container doesn't have access to your SSH credentials, or the right user name, or perhaps other things needed to release a gem. But for simple testing, it works.
 
+#### Troubleshooting Docker
+
+- With the above configuration, the gems are kept in `vendor/bundle` on your hosts, which is `$GEM_HOME` or `/app/vendor/bundle` in the running Docker container. If you're having permission problems when switching versions of Ruby or Rails, you can try `sudo rm -rf vendor/bundle` on the host, then run `BUNDLE_GEMFILES=gemfiles/7.0.gemfile bundle update` in the Docker container to re-install all the gems with the right permissions.

 ### The Demo Application
 
 There is a demo app in this repository. It shows some of the features of `bootstrap_form`, and provides a base on which to build ad-hoc testing, if you need it.
