+# Packaging Container
+
+This is the openSUSE packaging container image, it includes all the necessary
+software to create and modify packages on the [Open Build
+Service](https://build.opensuse.org/) using
+[osc](https://github.com/openSUSE/osc/).
+
+
+## How to use this container image
+
+This container image is intended for interactive usage with your `.oscrc`
+mounted into the container:
+
+```ShellSession
+# podman run --rm -it -v ~/.config/osc/oscrc:/root/.config/osc/oscrc:Z \
+    {{ image.reference }}
+```
+
+The above command launches an interactive shell where your local osc config will
+be used. You can then proceed to checkout packages, perform modifications and
+send submissions to OBS.
+
+You can also let the container image's entrypoint generate a `oscrc` for you
+using the environment variables `OSC_USER` and `OSC_PASSWORD`. It will create a
+configuration for the OBS instance with the API URL saved in the environment variable
+`OSC_APIURL` (defaults to api.opensuse.org):
+
+```ShellSession
+# podman run --rm -it -e OSC_USER=my_user -e OSC_PASSWORD=mySecretPassword \
+    {{ image.reference }}
+```
+
+Note that you should disable your shell's history as it will otherwise container
+your password in plain text.
+
+
+## Limitations
+
+- It is currently not possible to build packages in a container.
+
+- Cannot communicate with build.suse.de
+
+
+## Volumes
+
+The container image is preconfigured to put `/var/tmp` into a volume. This
+directory is used by `osc` to store the buildroot and the package cache.
