There are some other sources of information for learning about developing on Solr: 1. The help .txt files for the Gradle commands in the `help/` directory. 2. Information on how to handle adding dependencies and related licensing details, see the information in `/solr/licenses/README.committers.txt`. 3. The Solr Reference Guide, which provides primarily end user oriented documentation. However, the Ref Guide hosts it's own documentation on how to write Ref Guide content. There are a number of tools related to doing development on Solr available in the `/dev-tools` directory.
