+## Naming Convention For Bundles
+
+Bundles are named according to the following convention:
+
+```text
+<prefix>-<type>-<id>
+```
+
+where
+
+- **prefix** is the first element to categorize the bundle.
+  For addons this is often `openhab` or `esh`. 
+- **type** is the add-on type, e.g. "binding" or "ui"
+- **id** is the identifier for this bundle
+
+The naming convention has many effects you may not have noticed before, but used already.
+For example in the Paper UI the *sorted tabs* for all bindings are generated automatically based on the bundle naming.
+
+In many places (e.g. logging) you will also have the **package namespace** as an identifier.
+You can find it as the *Symbolic name* of the bundle with the following command:
+
+```text
+openhab> bundle:list -s
+ ID | State    | Lvl | Version                | Name                        | Symbolic name
