+# Pongo2 
+ The [PONGO2](https://github.com/flosch/pongo2) Templating Plugin
+
+- Pongo2 templates may be identified by a `shebang` on the first line 
+(preferred method) or changing the file extension to home.pongo2.html. 
+ By default the operation of revel assumes just a `.html` extension for
+ controller responses so it would make more sense to use the shebang
+- Pongo2 templates can be set to be case sensitive by setting
+`pongo2.tempate.caseinsensitive=false`, default is not case sensitive. If case sensitivity is 
+off the templates are compiled using lower case
+- Currently the only functions built in are as follows:
+  - field
+  - radio
+  - option
+  - url
+  - checkbox
+  - append
+  
+  Samples implementation below  
+
+##### Details

+
+Install/update using `go get` (no dependencies required by pongo2):
+```
