 It needs a `Gemfile` under the [`working-directory`](#working-directory).  
 The caching works whether there is a `Gemfile.lock` or not.
 If there is a `Gemfile.lock`, `bundle config --local deployment true` is used.

 To perform caching, this action will use `bundle config --local path vendor/bundle`.  
 Therefore, the Bundler `path` should not be changed in your workflow for the cache to work.

 ## Limitations
 
-* This action currently only works with GitHub-hosted runners, not private runners.
+### Using self-hosted runners
+You must meet the following parameters to use this action with self-hosted runners:
+
+* Make sure that the operating system has `libyaml-0` installed
+* The runner software is running as user `runner` with a home directory of `/home/runner`, or you have created a symlink for the home directory of whatever user that the runner is running as to `/home/runner`.
