+Running Certbot in Docker 
+=========================
+
+Docker is an amazingly simple and quick way to obtain a certificate. However, this mode of operation is unable to install certificates automatically or configure your webserver, because our installer plugins cannot reach your webserver from inside the Docker container.
+ 
+**Most users should install Certbot by following the installation instructions at https://certbot.eff.org/instructions. You should only use Docker if you are sure you know what you are doing (you understand [volumes](https://docs.docker.com/storage/volumes/)) and have a good reason to do so, such as following the [one service per container rule](https://docs.docker.com/config/containers/multi-service_container/).**
+
+For more information, please read [Certbot - Running with Docker](https://certbot.eff.org/docs/install.html#running-with-docker).
+
+Certbot-Docker project
+======================
+
+Goal
+----
+
+This project is used to publish a new version of the official Certbot Docker and related Certbot DNS plugins Dockers on DockerHub upon release of a new version of Certbot.
+It leverages the AutoBuild features of DockerHub to coordinate this publication through a continous integration/deployment approach.
+
+High-level behavior
+-------------------
+
+When a new version tag (eg. v0.35.0) is pushed to this repository, it triggers a new build in each DockerHub project, to construct and publish the new version of the Docker
+containing the Certbot version corresponding to the pushed tag. For example, after following the instructions for v0.35.0 below, after a few minutes the DockerHub projects will contain a new tag "v0.35.0",
+whose Docker contains Certbot v0.35.0.
+
+Configuration
+-------------
+
+To set up the publication process, the target DockerHub project must be configured appropriately. There are two types of DockerHub projects to take into account:
+* the Docker project for Certbot core features (eg. certbot/certbot)
+* a Docker project for Certbot DNS plugins (eg. certbot/dns-rfc2136)
+
+1) Define a GitHub user with push rights to the current GIT repository.
+2) Create the DockerHub project if necessary.
+3) Activate the AutoBuild feature, using the current GIT repository as source (eg. https://github.com/certbot-docker/certbot-docker.git) and the user defined in 1).
+4) Define a unique tag build rule in AutoBuild configuration:
+
+    _For a Certbot core Docker_ -> Source: `/^(v[0-9.]+).*$/`, Tag: `{\1}`, Dockerfile: `Dockerfile`, Build context: `/core`
+
+    _For a Certbot DNS plugin Docker_ -> Source: `/^(v[0-9.]+).*$/`, Tag: `{\1}`, Dockerfile: `Dockerfile`, Build context: `/plugin`
+
+Publication worfklow
+-------------------
+
+Assuming the version to publish is `v0.35.0`
+
+1) Clone this repository locally, check out branch `master`, and ensure the workspace is clean.
+2) (Optional) Execute `./build.sh v0.35.0` to test the Docker builds.
+3) Execute `./deploy.sh v0.35.0` to trigger the publication of all Dockers with version `v0.35.0`.
+
+Scripts usage
+-------------
+
+```
+./build.sh [VERSION]
+```
+
+This script will locally build all Dockers for the given version using the same runtime as DockerHub.
+This can be used to test the build process before invoking the actual publication workflow.
+
+```
+./deploy.sh [VERSION]
+```
+
+This script will trigger the publication of all Dockers for the given version to DockerHub. To do so, this script will:
+- update the relevant `README.md` files that will be used as descriptions in the DockerHub repositories,
+- locally commit the modifications,
+- tag this commit with the given version,
+- push this tag and the updated `master` branch.
+
+Assuming the version to publish is `v0.35.0`, the following docker images will be created at DockerHub.
+
+- certbot/certbot:v0.35.0 *(amd64 architecture)*
+- certbot/certbot:amd64-v0.35.0
+- certbot/certbot:arm32v6-v0.35.0
+- certbot/certbot:arm64v8-v0.35.0
+- certbot/certbot:latest *(amd64 architecture)*
+- certbot/certbot:amd64-latest
+- certbot/certbot:arm32v6-latest
+- certbot/certbot:arm64v8-latest
