 Welcome to |project|'s documentation!
 =====================================
 
-|Project| provides tools for analyzing and building software projects.
+The Research Development Toolkit (|project|) consists of tools and
+processes which help software engineers working on complex,
+heterogeneous, software-intensive systems in the following regards:
+
+* Continuous Integration (CI) and Deployment (onto diverse target
+  platforms)
+
+* Reproducibility
+
+* Handling of dependencies
+
+* Documentation, cataloging, meta-data and re-use
+
+In the Cluster of Excellence Cognitive Interactive Technology (CITEC_)
+at Bielefeld University is used for internal projects as well as in
+cooperation with external partners. So far, 1,400 software
+:term:`projects <project>` and about 200 :term:`distributions
+<distribution>` have been modeled by more than 100 contributors.
+
+Examples of :term:`distributions <distribution>` in the areas research
+and education whose requirements are met by the |project| include an
+intelligent apartment, workbenches for domain-specific languages,
+service robots, etc. Many of these distributions are comprised of
+hundreds of :term:`projects <project>` from diverse domains such as
+machine learning, natural language understanding and synthesis,
+databases and system monitoring and are mainly developed and
+maintained by (PhD) students.
+
+In contrast to other CI and DevOps solutions and services, the
+model-based approach employed in the |project| is particularly
+suitable for heterogeneous systems combining divers project kinds,
+inclusion of 3rd-party elements and complex dependency structures.
