 word" style generator but instead a string of characters to match the exact
 length. This can be useful if you have to generate "key" style values instead
 of passwords which admins have to type out in database shells.

+- Publish your new recipe on the [git.coopcloud.tech](https://git.coopcloud.tech/coop-cloud) listing
+- Run `abra catalogue generate <recipe> -p`
+- Run `cd ~/.abra/catalogue && make`
+
+These minimal steps will publish a new recipe with no versions. You can also do
+the [recipe release publishing dance](https://docs.coopcloud.tech/maintainers/handbook/#how-do-i-release-a-new-recipe-version)
+which will then extend the `versions: [...]` section of the published JSON in the catalogue.
+
+Recipes that are not included in the catalogue can still be deployed. It is not
+required to add your recipes to the catalogue but this will improve the
+visibility for other co-op hosters & end-users.
+
+In the future, we'd like to support [multiple catalogues](https://git.coopcloud.tech/coop-cloud/organising/issues/139).
