+# <a id="about"></a> About Icinga Web 2
+
+Icinga Web 2 is a powerful PHP framework for web applications that comes in a clean and reduced design.
+It's fast, responsive, accessible and easily extensible with modules.
+
+## <a id="about-monitoring"></a> The monitoring module
+
+This is the core module for most Icinga Web 2 users.
+
+It provides an intuitive user interface for monitoring with Icinga (1 and 2).
+Especially there are lots of list and detail views (e.g. for hosts and services)
+you can sort and filter depending on what you want to see.
+
+You can also control the monitoring process itself by sending external commands to Icinga.
+Most such actions (like rescheduling a check) can be done with just a single click.
+
+## <a id="about-installation"></a> Installation
+
+Icinga Web 2 can be installed easily from packages from the official package repositories.
+Setting it up is also easy with the web based setup wizard.

+See [here](installation#installation) for more information about the installation.

+Icinga Web 2 can be configured via the user interface and .ini files.

+and how to configure roles.
+
+## <a id="about-preferences"></a> User preferences

+Besides the global configuration each user has individual configuration options
+like the interface's language or the current timezone.
+They can be stored either in a database or in .ini files.

+See [here](preferences#preferences) for more information about a user's preferences
+and how to configure their storage type.
