+## Documentation
+
+We document the configuration in two ways:
+
+1. The configuration yaml default has comments documenting it. All documentation lines start with `##`. Lines starting 
+   with a single `#` are yaml configuration options which are commented to disable them or as examples.
+    
+2. This documentation site. Generally each section of the configuration is in its own section of the documentation 
+   site. Each configuration option is listed in its relevant section as a heading, under that heading generally are two
+   or three colored labels. 
+   - The `type` label is purple and indicates the yaml value type of the variable. It optionally includes some 
+     additional information in parentheses.
+   - The `default` label is blue and indicates the default value if you don't define the option at all. This is not the 
+     same value as you will see in the examples in all instances, it is the value set when blank or undefined.
+   - The `required` label changes color. When required it will be red, when not required it will be green, when the 
+     required state depends on another configuration value it is yellow.
