+Thunderbird build environment prep for run-task,
+for use with comm-central derived repositories.
+
+This script is meant to run prior to run-task on repositories like
+comm-central that need to check out a copy of a mozilla repository
+in order to build.
+See bug 1491371 for background on why this is necessary.
+
+A project will have a file named ".gecko_rev.yml" in it's root. See the
+constant "GECKO_REV_CONF" if you want to change that. To download it, the
+script uses the project repository URL and the revision number.
+Those are defined in the environment variables:
+COMM_HEAD_REPOSITORY
+COMM_HEAD_REV
+
+.gecko_rev.yml has a structure like (for comm-central):
+```
+GECKO_BASE_REPOSITORY: https://hg.mozilla.org/mozilla-unified
+GECKO_HEAD_REPOSITORY: https://hg.mozilla.org/mozilla-central
+GECKO_HEAD_REF: default
+```
+or for branches:
+```
+GECKO_BASE_REPOSITORY: https://hg.mozilla.org/mozilla-unified
+GECKO_HEAD_REPOSITORY: https://hg.mozilla.org/releases/mozilla-beta
+GECKO_HEAD_REF: THUNDERBIRD_60_VERBRANCH
+GECKO_HEAD_REV: 6a830d12f15493a70b1192022c9985eba2139910
+
+Note about GECKO_HEAD_REV and GECKO_HEAD_REF:
+GECKO_HEAD_REF is a branch name or "default".
+GECKO_HEAD_REV is a revision hash.

+Index-Image
+===========
+
+This image is designed to be used for indexing other tasks. It takes a task
+definition as follows:
+```js
+{
+  ...,
+  scopes: [
+    'index:insert-task:my-index.namespace',
+    'index:insert-task:...',
+  ],
+  payload: {
+    image: '...',
+    env: {
+      TARGET_TASKID: '<taskId-to-be-indexed>',
+    },
+    command: [
+      'insert-indexes.js',
+      'my-index.namespace.one',
+      'my-index.namespace.two',
+      '....',
+    ],
+    features: {
+      taskclusterProxy: true,
+    },
+    maxRunTime: 600,
+  },
+}
+```
+
+As can be seen the `taskId` to be indexed is given by the environment variable
+`TARGET_TASKID` and the `command` arguments specifies namespaces that it must
+be index under. It is **important** to also include scopes on the form
+`index:insert-task:<...>` for all namespaces `<...>` given as `command`
+arguments.

+
+==Periodic File Updates==
+
+This docker image examines the in-tree files for HSTS preload data, HPKP pinning and blocklisting, and
+will produce a diff for each necessary to update the in-tree files.
+
+If given a conduit API token, it will also use the arcanist client to submit the commits for review.
+
+
+==Quick Start==
+
+```sh
+docker build -t hsts-local --no-cache --rm .
+
+docker run -e DO_HSTS=1 -e DO_HPKP=1 -e PRODUCT="firefox" -e BRANCH="mozilla-central" -e USE_MOZILLA_CENTRAL=1 hsts-local
+```
+
+HSTS checks will only be run if the `DO_HSTS` environment variable is set.
+Likewise for `DO_HPKP` and the HPKP checks. Environment variables are used
+rather than command line arguments to make constructing taskcluster tasks
+easier.
+
+To prevent a full build when landing with Phabricator, set the `DONTBUILD`
+environment variable.
+
+==Background==
+
+These scripts have been moved from
+`https://hg.mozilla.org/build/tools/scripts/periodic_file_updates/` and
+`security/manager/tools/` in the main repos.
+
+==HSTS Checks==
+
+`scripts/getHSTSPreloadList.js` will examine the current contents of
+nsSTSPreloadList.inc from whichever `BRANCH` is specified, add in the mandatory
+hosts, and those from the Chromium source, and check them all to see if their
+SSL configuration is valid, and whether or not they have the
+Strict-Transport-Security header set with an appropriate `max-age`.
+
+This javascript has been modified to use async calls to improve performance.
+
+==HPKP Checks==
+
+`scripts/genHPKPStaticPins.js` will ensure the list of pinned public keys are
+up to date.
+
+==Example Taskcluster Task==
