+
+===========================
+Creating Toolchain Archives
+===========================
+
+There are various scripts in the repository for producing archives
+of the build tools (e.g. compilers and linkers) required to build.
+
+Clang
+=====
+
+See the ``build/build-clang`` directory. Read ``build/build-clang/README``
+for more.
+
+Windows
+=======
+
+The ``build/windows_toolchain.py`` script is used to build and manage
+Windows toolchain archives containing Visual Studio executables, SDKs,
+etc.
+
+The way Firefox build automation works is an archive containing the
+toolchain is produced and uploaded to an internal Mozilla server. The
+build automation will download, verify, and extract this archive before
+building. The archive is self-contained so machines don't need to install
+Visual Studio, SDKs, or various other dependencies. Unfortunately,
+Microsoft's terms don't allow Mozilla to distribute this archive
+publicly. However, the same tool can be used to create your own copy.
+
+Configuring Your System
+-----------------------
+
+It is **highly** recommended to perform this process on a fresh installation
+of Windows 7 or 10 (such as in a VM). Installing all updates through
+Windows Update is not only acceptable - it is encouraged. Although it
+shouldn't matter.
+
+Next, install Visual Studio 2015 Community. The download link can be
+found at https://www.visualstudio.com/en-us/products/visual-studio-community-vs.aspx.
+Be sure to follow these install instructions:
+
+1. Choose a ``Custom`` installation and click ``Next``
+2. Select ``Programming Languages`` -> ``Visual C++`` (make sure all sub items are
+ selected)
+3. Under ``Windows and Web Development`` uncheck everything except
+ ``Universal Windows App Development Tools`` and the items under it
+ (should be ``Tools (1.3.1)...`` and the ``Windows 10 SDK``).
+
+Once Visual Studio 2015 Community has been installed, from a checkout
+of mozilla-central, run something like the following to produce a ZIP
+archive::
+
+ $ ./mach python build/windows_toolchain.py create-zip vs2015u3
+
+The produced archive will be the argument to ``create-zip`` + ``.zip``.
+
+Firefox for Android with Gradle
+===============================
+
+To build Firefox for Android with Gradle in automation, archives
+containing both the Gradle executable and a Maven repository
+comprising the exact build dependencies are produced and uploaded to
+an internal Mozilla server. The build automation will download,
+verify, and extract these archive before building. These archives
+provide a self-contained Gradle and Maven repository so that machines
+don't need to fetch additional Maven dependencies at build time.
+(Gradle and the downloaded Maven dependencies can be both
+redistributed publicly.)
+
+Archiving the Gradle executable is straight-forward, but archiving a
+local Maven repository is not. Therefore a special Task Cluster
+Docker image and job exist for producing the required archives. The
+Docker image definition is rooted in
+``taskcluster/docker/android-gradle-build``. The Task Cluster job
+definition is in
+``testing/taskcluster/tasks/builds/android_api_15_gradle_dependencies.yml``.
+The job runs in a container based on the custom Docker image and
+spawns a Sonatype Nexus proxying Maven repository process in the
+background. The job builds Firefox for Android using Gradle and the
+in-tree Gradle configuration rooted at ``build.gradle``. The spawned
+proxying Maven repository downloads external dependencies and collects
+them. After the Gradle build completes, the job archives the Gradle
+version used to build, and the downloaded Maven repository, and
+exposes them as Task Cluster artifacts.
+
+Here is `an example try job fetching these dependencies
+<https://treeherder.mozilla.org/#/jobs?repo=try&revision=75bc98935147&selectedJob=17793653>`_.
+The resulting task produced a `Gradle archive
+<https://queue.taskcluster.net/v1/task/CeYMgAP3Q-KF8h37nMhJjg/runs/0/artifacts/public%2Fbuild%2Fgradle.tar.xz>`_
+and a `Maven repository archive
+<https://queue.taskcluster.net/v1/task/CeYMgAP3Q-KF8h37nMhJjg/runs/0/artifacts/public%2Fbuild%2Fjcentral.tar.xz>`_.
+These archives were then uploaded (manually) to Mozilla automation
+using tooltool for consumption in Gradle builds.
+
+To update the version of Gradle in the archive produced, update
+``gradle/wrapper/gradle-wrapper.properties``. Be sure to also update
+the SHA256 checksum to prevent poisoning the build machines!
+
+To update the versions of Gradle dependencies used, update
+``dependencies`` sections in the in-tree Gradle configuration rooted
+at ``build.gradle``. Once you are confident your changes build
+locally, push a fresh try build with an invocation like::
+
+ $ hg push-to-try -m "try: -b o -p android-api-15-gradle-dependencies"
+
+Then `upload your archives to tooltool
+<https://wiki.mozilla.org/ReleaseEngineering/Applications/Tooltool#How_To_Upload_To_Tooltool>`_,
+update the in-tree manifests in
+``mobile/android/config/tooltool-manifests``, and push a fresh try
+build.
