+Usage
+
+  rvm-installer [options] [action]
+
+Options
+
+  [[--]version] <version>
+
+    The version or tag to install. Valid values are:
+
+      latest         - The latest tagged version.
+      latest-minor   - The latest minor version of the current major version.
+      latest-<x>     - The latest minor version of version x.
+      latest-<x>.<y> - The latest patch version of version x.y.
+      <x>.<y>.<z>    - Major version x, minor version y and patch z.
+
+  [--]branch <branch>
+
+    The name of the branch from which RVM is installed. This option can be used
+    with the following formats for <branch>:
+
+      <account>/
+
+        If account is rvm or mpapis, installs from one of the following:
+
+          https://github.com/rvm/rvm/archive/master.tar.gz
+          https://bitbucket.org/mpapis/rvm/get/master.tar.gz
+
+       Otherwise, installs from:
+
+         https://github.com/<account>/rvm/archive/master.tar.gz
+
+      <account>/<branch>
+
+        If account is rvm or mpapis, installs from one of the following:
+
+          https://github.com/rvm/rvm/archive/<branch>.tar.gz
+          https://bitbucket.org/mpapis/rvm/get/<branch>.tar.gz
+
+        Otherwise, installs from:
+
+          https://github.com/<account>/rvm/archive/<branch>.tar.gz
+
+      [/]<branch>
+
+        Installs the branch from one of the following:
+
+          https://github.com/rvm/rvm/archive/<branch>.tar.gz
+          https://bitbucket.org/mpapis/rvm/get/<branch>.tar.gz
+
+      [--]source <source>
+
+        Defines the repository from which RVM is retrieved and installed in the format:
+
+          <domain>/<account>/<repo>
+
+        Where:
+
+          <domain>  - Is bitbucket.org, github.com or a github enterprise site serving
+                      an RVM repository.
+          <account> - Is the user account in which the RVM repository resides.
+          <repo>    - Is the name of the RVM repository.
+
+        Note that when using the [--]source option, one should only use the [/]branch format
+        with the [--]branch option. Failure to do so will result in undefined behavior.
+
+      --trace
+
+        Provides debug logging for the installation script.
+Actions
+
+  master - Installs RVM from the master branch at rvm/rvm on github or mpapis/rvm
+           on bitbucket.org.
+  stable - Installs RVM from the stable branch a rvm/rvm on github or mpapis/rvm
+           on bitbucket.org.
+  help   - Displays this output.
