+#+TITLE: Org Generate Boilerplate Templates
+
+* Introduction
+
+This document contains boilerplate templates for generating stuff.
+
+To use use ~M-x org-generate~ and select the template you want to
+generate.
+
+Templates start at level 2. Specify the root folder for the generated
+files.
+
+Headings with a "/" at the end signify folders to be created to add
+additional files into.
+
+You can define variables and use them in the templates using the
+typical mustache syntax {{variable}}. Variables are defined in the
+~org-generate-variable~ property in the properties drawer of the the
+template subtree.
+
+*IMPORTANT* The code relies on ~#+begin_src~ and ~#+end_src~ blocks to be
+written in lower case. The code looks for these case sensitively.
