+Collection of PHP scripts to complement OpenSimulator features.
 
 ## Description
 
-Helpers required to enable common functionalties like search, currency, events in OpenSimulator grids.
+Collection of PHP scripts to enable OpenSimulator features that are not implemented in the core, like search, currency, events in OpenSimulator grids (see Features below).
+
+Most files are used directly by viewer to allow features not implemented in OpenSimulator, like classifieds, events, etc.
 
 They were initially based on a collection of different projects (see Credits below), but were entirely rewritten to use an unified code and set of parameters, as well as for integration in larger projects like [w4os OpenSim WordPress Interface](https://w4os.org/).
 
 Formerly known as Flexible Helper Scripts.
