-### Quick start
+# Neurofield
+
+This library implements methods to simulate neural field models,
+based on Robinson's Neural Field Theory.
+
+
+## Installation
+
+1. Fork and clone; or,
+
+2. download the latest [release](https://github.com/BrainDynamicsUSYD/neurofield/releases) as a `.zip` or `tar.gz` file.
+
+### Build/compilation
 
 To build the executable on Linux or Mac, open a terminal in the neurofield directory and type:
 
     make
 
-this produces the executable (bin/neurofield). The user-manual is available as doc/NeurofieldManual.pdf.

 To build the reference manual, generated from the code, type:
 
     make reference-manual
 
-The html files for the reference-manual will be place under `doc/html`, point your browser at the index.html file in that directory.
