+# Distribution
+
+[Distribution](https://github.com/distribution/distribution) is a toolkit to pack, ship, store, and deliver container content
+
+> When application is installed, a container will be launched with **root** privileges.
+> This is required in order to apply the correct permissions to the `Distribution` directories.
+> Afterward, the `Distribution` container will run as a **non**-root user (Default: `568`).
+> All mounted storage(s) will be `chown`ed only if the parent directory does not match the configured user.
