 Skosmos
 =======
+
+Skosmos is a web-based tool providing services for accessing controlled
+vocabularies, which are used by indexers describing documents and searchers
+looking for suitable keywords.  Vocabularies are accessed via SPARQL
+endpoints containing SKOS vocabularies.
+
+In addition to a modern web user interface for humans, Skosmos provides a
+REST-style API and Linked Data access to the underlying vocabulary data.
+
+Skosmos is used as a basis for the Finto vocabulary service. The latest
+development version is also available at dev.finto.fi.
+
+Skosmos is implemented using PHP, with Twig templates and e.g. jQuery and
+jsTree used to build the web interface, and EasyRdf for SPARQL and RDF data
+access.
+
+The code is open source under the MIT license. See Installation in the wiki
+for details on obtaining the source and running your own instance of 
+Skosmos.
+
+For information about current and future versions, see ReleaseNotes and
+Roadmap.
+
+Skosmos was formerly known as ONKI Light.
