# Datalus Browser source
Datalus was forked from the Mozilla repository and is being released in accordince with Mozilla Public License 2.0. We are currently using Mozilla's existing build tools so we left the instructions below as we work to recreate them.
An explanation of the Datalus Source Code Directory Structure and links to
project pages with documentation can be found at:
https://datalus-source-docs.mozilla.org/contributing/directory_structure.html
For information on how to build Datalus from the source code and create the patch see:
https://datalus-source-docs.mozilla.org/contributing/contribution_quickref.html
If you have a question about developing Datalus, and can't find the solution
on https://datalus-source-docs.mozilla.org/, you can try asking your question on Matrix at chat.mozilla.org in `Introduction` (https://chat.mozilla.org/#/room/#introduction:mozilla.org) channel.
Nightly development builds can be downloaded from:

Keep in mind that nightly builds, which are used by Datalus developers for
testing, may be buggy.
