+### Updating Gradle Dependencies
+If additional Android dependencies are required by the project's build, then
+the Gradle build will fail due to missing dependencies. To find out what the
+missing dependencies are, comment out the following line in the project's build
+file:
+
+   export GRADLE_MAVEN_REPOSITORIES="file://$rootdir/[% c('input_files_by_name/gradle-dependencies') %]"
+
+and rerun the build.
+
+Dependent artifacts will show up as downloads in the logs. You can pull out
+these dependencies into a list with the following command (replacing
+"firefox-android-armv7.log" with the build log file name of the actual project):
+
+`cat logs/firefox-android-armv7.log | grep "Download http" | sed "s/^.*Download //g" > download-urls.txt`
+
+You will then need to add the new dependency URLs and SHA-256 values into the
+projects/$project/gradle-dependencies-list.txt file. The format of this file is
+pipe delimited
+   sha256sum | url
+
+Finally, in the project's config file increment the
+var/gradle_dependencies_version and make sure to restore the project's build
+file back to original.
+
+It may also be the case that you wish to clean up old versions of the artifacts.
+For this you will need to run the build with a
+gradle-dependencies-list.txt file containing only the headers. Make sure to also
+comment the GRADLE_MAVEN_REPOSITORIES line from the project's build file. You
+can now proceed to reconstruct the list as given above.
