-then you haven't run `npm install` yet.
+2. To hold release automation scripts
+  - e.g. coho create-archive && coho verify-archive
+  - e.g. CrowdIn scripts
 
-Suggested way to install `node` is to use `nvm`:
+3. To hold committer process documentation
+  - e.g. ProcessingPullRequests
 
-    curl https://raw.github.com/creationix/nvm/master/install.sh | sh
-    source ~/.bash_profile
-    nvm install 0.10
-    nvm alias default 0.10
