 	<h3>Permissions and access control</h3>
+
+	<p>The key part of enforcing access control for a project takes place in the User Permissions page, at</p>
+
+	<p class="hint">Admin &gt; User Permissions</p>
+
+	<p>
+	This page allows the project manager to define which users can read,
+	write or update the project's contents. Permissions are assigned by user groups.
+	Each project is created with an Admin, Developers, and Member.
+	But new user groups can be defined to further extend the control.

+
+	<p>The various tools in the platform inherit the general project
+	permissions, however some tools provide even more detailed access
+	control settings, enforcing per tool or per content access control.</p>
