 Parse Diameter AVP groups and messages and convert them to a
 model. The model can be used to generate efficient C/C++ codec
 code and a highly flexible Smalltalk toolkit.
+
+## Installation
+
+To install diameter on your Pharo image, execute the following script: 
+
+```Smalltalk
+Metacello new
+	githubUser: 'moiji-mobile' project: 'diameter' commitish: 'master' path: 'mc';
+	baseline: 'Diameter';
+	load
+```
+
+To add diameter to your baseline:
+
+```Smalltalk
+spec
+	baseline: 'Diameter'
+	with: [ spec repository: 'github://moiji-mobile/diameter:master/mc' ]
+```
+
+Note you can replace the #master by another branch such as #development or a tag such as #v1.
