+
+### About the Incubator Project
+
+Apache Brooklyn was in the Apache Incubator until the end of 2015, on version `0.9.0-SNAPSHOT`.
+At this time it graduated to become a top-level Apache Software Foundation project,
+and the code moved from `incubator-brooklyn` to `brooklyn` and several other projects `brooklyn-*`.
+
+Versions `0.8.0-incubating` and before can be found in and built from this repo,
+along with the last commit to `0.9.0-SNAPSHOT` from which development has continued
+in `apache/brooklyn` and sub-projects.
+
+The sub-directories in this project correspond to multiple separate repositories now in the `apache` org.
+The link above to **[the Active Codebase](http://github.com/apache/brooklyn/)** started life exactly 
+as a copy of [`brooklyn/`](brooklyn/) in this folder, 
+as an uber-project for the other `brooklyn-*` folders, including the `server` and the `ui`,
+which are now top-level repos in the `apache` org.
+
+
+### To Build
+
+This historic version of the code can be built with:
+
+    mvn clean install
+
+This creates a build of the last incubator SNAPSHOT version in `usage/dist/target/brooklyn-dist`. Run 
+with `bin/brooklyn launch`. Although really you probably want **[the Active Codebase](http://github.com/apache/brooklyn/)**.
