+This command generates a new copy of the recipe catalogue which can be found on:
+
+    https://recipes.coopcloud.tech
+
+It polls the entire git.coopcloud.tech/coop-cloud/... recipe repository
+listing, parses README and tags to produce recipe metadata and produces a
+apps.json file which is placed in your ~/.abra/catalogue/recipes.json.
+
+It is possible to generate new metadata for a single recipe by passing
+<recipe>. The existing local catalogue will be updated, not overwritten.
+
+A new catalogue copy can be published to the recipes repository by passing the
+"--commit" and "--push" flags. The recipes repository is available here:
+
+    https://git.coopcloud.tech/coop-cloud/recipes
