 > **Warning**
 > To start, you *must* create a branch called `live` which is exclusively for your customizations. That is the **only** branch the GitHub workflow will deploy to your container registry. Don't make any changes to the original "template" branch. It should remain untouched. By using this branch structure, you ensure a clear separation between your own "published image" branch, your development branches, and the original upstream "template" branch. Periodically sync and fast-forward the upstream "template" branch to the most recent revision. Then, simply rebase your `live` branch onto the updated template to effortlessly incorporate the latest improvements into your own repository, without the need for any messy, manual "merge commits".

 To build multiple images, you need to create another recipe.yml file, which you should name based on what kind of image you want it to build. Then, edit the [`build.yml`](../.github/workflows/build.yml) file. Inside the file, under `jobs: strategy: matrix:`, there's a list of recipe files to build images, which you need to add your new recipe file to. These should be paths to files inside the `config` directory.
 
-Module configuration can be included from other files using the `from-file` syntax. The valye should be a path to a file inside the `config` directory. For example, the following snippet could be used to include the configuration for installing a set of packages common to multiple images.
