-* `MIRROR_ARCHITECTURES`
-    * default `amd64`. 
+## Paths
+
+The mirror stores all the data in a docker volume at path
+`/var/mirror/ubuntu`.  Map that somewhere else if you like.
+
+## Environment Variables
+
+* `UBUNTU_MIRROR_ARCHITECTURES`
+    * default `amd64`.
     * You may want `i386,amd64`.
-* `MIRROR_CATEGORIES`
-    * default `main,universe`.
-    * You may want `main,universe,restricted,multiverse`. Will use lots of
-      disk.
+* `UBUNTU_MIRROR_CATEGORIES`
+    * Default `main,universe,restricted,multiverse`. Will use lots of disk.
+    * You may want `main,universe`.
 * `UBUNTU_MIRROR_PROJECTS`
-    * default `xenial,xenial-updates,xenial-security,xenial-backports,bionic,bionic-updates,bionic-security,bionic-backports`.
-* `UBUNTU_MIRROR_SOURCE`
+    * Default
+      `bionic,bionic-updates,bionic-security,bionic-backports,focal,focal-updates,focal-security,focal-backports`.
+    * You may want only `focal,focal-updates,focal-security,focal-backports`.
+* `UBUNTU_MIRROR_UPSTREAM` - upstream server to mirror from
     * default `archive.ubuntu.com`.
     * You may want `xx.archive.ubuntu.com` (where `xx` is your country
       code).
-* `MIRROR_INTERVAL_SECONDS` - mirror sync interval
+* `UBUNTU_ENABLE_SOURCE_MIRRORING` - do we want to mirror all the source code too?
+    * Default ``
+    * You may want `1` if you want to use up even more disk for your mirror
+* `MIRROR_UPDATE_INTERVAL_SECONDS` - mirror update interval
     * default `43200` (12h)
     * You may want `10800` (3h)
