 ## How to use
 
+### Templating
+
 Once you have the CLI tool installed, you can run the following to pull in your recipe file to generate a `Containerfile`.
 
 ```bash
 ublue template -o <CONTAINERFILE> <RECIPE_FILE>
 ```
 
-You can then use this with `podman` to build and publish your image. Further options can be viewed by running `ublue --help`

+
+### Building
+
+If you don't care about the details of the template, you can run the `build` command.
+
+```bash
+ublue build ./config/recipe.yaml
+```
+
+This will template out the file and build with `buildah` or `podman`. If you're running in Gitlab CI with the pipeline like in the [init template](templates/init/gitlab-ci.yml.tera), it will automatically sign your image using Gitlab's own OIDC service.
