+Deployment
+==========
+
+Reader Service
+--------------
+
+The *reader* service is made of three components:
+
+- a folder where the Remote Settings Data git repository is checked out
+- a Web API service that points to this folder
+- a cronjob that regularly pulls the latest data from the Git origin
+
+The reader service has two modes:
+
+- ``SELF_CONTAINED=false`` (*default*): only collection data is served by the Web API. Certificate chains are served from the Autograph CDN and attachments are served from the ``ATTACHMENTS_BASE_URL`` domain.
+- ``SELF_CONTAINED=true``: everything is served by the Web API: collection data, certificate chains, attachments. This is relevant when the clients activity must be confined to a single server/domain (eg. on premise instance).
+
+
+Official Git Repositories
+'''''''''''''''''''''''''
+
+- **Production** data: ``git@github.com:mozilla/remote-settings-data.git``
+- **Stage** data: ``git@github.com:mozilla/remote-settings-data-stage.git``
+- **Dev** data: ``git@github.com:mozilla/remote-settings-data-dev.git``
+
+.. note::
+
+    Using forks of these repositories is possible. However, forks must be kept up-to-date since the
+    certificates chains and signatures are short-lived (6 weeks). And modifying data would require
+    disabling signature verification on the client.
+
+
+Official Docker Images
+''''''''''''''''''''''
+
+* **Stable**: ``us-docker.pkg.dev/moz-fx-remote-settings-prod/remote-settings-prod/remote-settings-git-reader`` (Published on release tags)
+* **Dev**: ``us-docker.pkg.dev/moz-fx-remote-settings-nonprod/remote-settings-stage/remote-settings-git-reader`` (Published on each code change)
+
+
+Container Entry Points
+''''''''''''''''''''''
+
+* ``web`` (*default*): runs the Web API on port ``8000`` with Prometheus metrics on port ``9090``. The following env vars must be set:
+  - ``GIT_REPO_PATH``: the path to the checked out git repo folder
+  - ``SELF_CONTAINED``: whether to serve everything from the Web API
+  - ``ATTACHMENTS_BASE_URL``: the attachments base URL if ``SELF_CONTAINED=false``
+
+* ``gitupdate``: initializes or update the checked out git repo folder. Requires the following settings:
+  - ``GIT_REPO_PATH``: the path to the checked out git repo folder
+  - ``GIT_REPO_URL``: the Git+SSH origin URL
+  - In order to avoid rate limiting with pulling large amounts of files from Git LFS, SSH authentication must be setup. Recommended way is to mount SSH keys into the container at ``/app/.ssh/id_ed25519`` and ``/app/.ssh/id_ed25519.pub``. See git-reader's README for more details.
+
+Liveliness and readiness probe at ``:8000/__lbheartbeat__``.
+
+
+Kubernetes Shared Volume
+''''''''''''''''''''''''
+
+With Kubernetes, the Git repo folder will be checked out in a shared volume (``PersistentVolumeClaim``).
+
+
+Monitoring
+''''''''''
+
+The Web API container exposes two sets of Prometheus metrics:
+
+- ``:8000/__metrics__``: Domain specific metrics (eg. repository read latency, repository age seconds, request summary, etc.)
+- ``:9090/``: Low level `Granian metrics <https://github.com/emmett-framework/granian/>_`
+
+All logs are sent to stdout in JSON format.
+

+
+
+Writer Service
+--------------
+
+The *writer* service is made of these components:
+
+- a Web API service
+- a PostgreSQL database
+- a cache backend (eg. Memcached or Redis)
+- a signing service (eg. Autograph)
+- a file storage service (eg. GCS or S3)
+- a series of cronjobs to refresh signatures, build startup and attachments bundles, export data to a Git repository, purge obsolete data, etc.
+
+Although it would totally be feasible to deploy your own Remote Settings writer instance, we officially don't support it.
