 The [ruby-build][] plugin provides an `rbenv uninstall` command to
 automate the removal process.
 
+### Uninstalling rbenv
+
+The simplicity of rbenv makes it easy to temporarily disable it, or
+uninstall from the system.
+
+1. To **disable** rbenv managing your Ruby versions, simply remove the
+  `rbenv init` line from your shell startup configuration. This will
+  remove rbenv shims directory from PATH, and future invocations like
+  `ruby` will execute the system Ruby version, as before rbenv.
+
+  `rbenv` will still be accessible on the command line, but your Ruby
+  apps won't be affected by version switching.
+
+2. To completely **uninstall** rbenv, perform step (1) and then remove
+   its root directory. This will **delete all Ruby versions** that were
+   installed under `` `rbenv root`/versions/ `` directory:
+
+        rm -rf `rbenv root`
+
+   If you've installed rbenv using a package manager, as a final step
+   perform the rbenv package removal. For instance, for Homebrew:
+
+        brew uninstall rbenv
