 This docker container can be used to quickly get a
 [WeeWX](http://weewx.com) instance up and running.
 
-This container has the following WeeWX extensions pre-installed:
-
-- [interceptor](https://github.com/matthewwall/weewx-interceptor)
-- [mqtt](https://github.com/weewx/weewx/wiki/mqtt)
-
 ## Running ##
 
-### Running with Docker ###
-
-Pull `felddy/weewx` from the Docker repository:
-
-```console
-docker pull felddy/weewx
-```
-
-### Run ###
-
 The easiest way to start the container is to create a
 `docker-compose.yml` similar to the following.  If you use a
 serial port to connect to your weather station, make sure the
-container has permissions to access the port.  The uid/gid can
-be set using the environment variables below.

+## Migrating ##
+
+If you are migrating a WeeWX installation, you need to configure the logger to
+write to the console. Add the following to your `weewx.conf` file to see the log
+output in the container logs:

+## Installing WeeWX Extensions ##
+
+If arguments are passed to the container, they are forwarded on to the
+[`weectl`](https://weewx.com/docs/5.1/utilities/weectl-about/) command.  This
+can be used to install extensions:
+
+```console
+docker compose run --rm weewx \
+  extension install --yes \
+  https://github.com/matthewwall/weewx-windy/archive/master.zip
+```
+

+docker compose run --rm weewx \
+  extension install --yes \
+  https://github.com/matthewwall/weewx-mqtt/archive/master.zip
+```
+
+## Installing Python Packages ##
+
+To install and persist Python packages, use the `pip` command. The libraries
+will be installed into the `data` volume, ensuring they persist between
+container restarts.
+
+```console
+docker compose run --rm --entrypoint pip weewx \
+  install git+https://github.com/felddy/weewx-home-assistant@v1.0.0
+```
+
+## Image tags ##
+
+The images of this container are tagged with [semantic
+versions](https://semver.org) that align with the [version and build of
+WeeWX](https://weewx.com/docs.html) that they support.
+
+> [!TIP]
+> It is recommended that users use the major version tag: `:5` Using the major
+> tag will ensure that you receive the most recent version of the software that
+> is compatible with your saved data, and prevents inadvertent upgrades to a new
+> major version.
+
+| Image:tag | Description |
+|-----------|-------------|
+|`felddy/weewx:5`| The most recent image matching the major version number.  Most users will use this tag. |
+|`felddy/weewx:5.1`| The most recent image matching the major and minor version numbers. |
+|`felddy/weewx:5.1.0`| An exact image version. |
+
+See the [tags tab](https://hub.docker.com/r/felddy/weewx/tags) on Docker
+Hub for a list of all the supported tags.
