+
+      pod setup
+        Creates a directory at `~/.cocoa-pods' which will hold your spec-repos.
+        This is where it will create a clone of the public `master' spec-repo.
+
+### Managing PodSpec files
+
+    $ pod help spec
+
+      pod spec create NAME
+        Creates a directory for your new pod, named `NAME', with a default
+        directory structure and accompanying `NAME.podspec'.
+
+      pod spec init NAME
+        Creates a PodSpec, in the current working dir, called `NAME.podspec'.
+        Use this for existing libraries.
+
+      pod spec lint NAME
+        Validates `NAME.podspec' from a local spec-repo. In case `NAME' is
+        omitted, it defaults to the PodSpec in the current working dir.
+
+      pod spec push REMOTE
+        Validates `NAME.podspec' in the current working dir, copies it to the
+        local clone of the `REMOTE' spec-repo, and pushes it to the `REMOTE'
+        spec-repo. In case `REMOTE' is omitted, it defaults to `master'.
+
+### Managing spec-repos
+
+    $ pod help repo
+
+      pod repo add NAME URL
+        Clones `URL' in the local spec-repos directory at `~/.cocoa-pods'. The
+        remote can later be referred to by `NAME'.
+
+      pod repo update NAME
+        Updates the local clone of the spec-repo `NAME'.
+
+      pod repo change NAME URL
+        Changes the git remote of local spec-repo `NAME' to `URL'.
