+## Container Image Tags
+
+New container images are built and published automatically every ~24h.
+
+> We recommend to use either the `vX.Y.Z-a.b.c` tags or the `vX.Y-a.b.c` tags in production!
+
+* `vX.Y.Z-a.b.c`, `vX.Y-a.b.c`:
+  These are release builds containing _NetBox version_ `vX.Y.Z`.
+  They contain the support files of _NetBox Docker version_ `a.b.c`.
+  You must use _NetBox Docker version_ `a.b.c` to guarantee the compatibility.
+  These images are automatically built from [the corresponding releases of NetBox][netbox-releases].
+* `latest-a.b.c`:
+  These are release builds, containing the latest stable version of NetBox.
+  They contain the support files of _NetBox Docker version_ `a.b.c`.
+  You must use _NetBox Docker version_ `a.b.c` to guarantee the compatibility.
+  These images are automatically built from [the `master` branch of NetBox][netbox-master].
+* `snapshot-a.b.c`:
+  These are pre-release builds.
+  They contain the support files of _NetBox Docker version_ `a.b.c`.
+  You must use _NetBox Docker version_ `a.b.c` to guarantee the compatibility.
+  These images are automatically built from the [`develop` branch of NetBox][netbox-develop].
+
+For each of the above tag, there is an extra tag:
+
+* `vX.Y.Z`, `vX.Y`:
+  This is the same version as `vX.Y.Z-a.b.c` (or `vX.Y-a.b.c`, respectively).
+  It always points to the latest version of _NetBox Docker_.
+* `latest`
+  This is the same version as `latest-a.b.c`.
+  It always points to the latest version of _NetBox Docker_.
+* `snapshot`
+  This is the same version as `snapshot-a.b.c`.
+  It always points to the latest version of _NetBox Docker_.
+

+
+* `-ldap`:

-## Breaking Changes
-
-From time to time it might become necessary to re-engineer the structure of this setup.
-Things like the `docker-compose.yml` file or your Kubernetes or OpenShift configurations have to be adjusted as a consequence.
-
-Since November 2019 each image built from this repo contains a `org.opencontainers.image.version` label.
-(The images contained labels since April 2018, although in November 2019 the labels' names changed.)
-You can check the label of your local image by running `docker inspect netboxcommunity/netbox:v2.7.1 --format "{{json .Config.Labels}}"`.
+## Updating
 
 Please read [the release notes][releases] carefully when updating to a new image version.
+Note that the version of the NetBox Docker container image must stay in sync with the code.
+
+If you update for the first time, be sure [to follow our _How To Update NetBox Docker_ guide in the wiki][netbox-docker-wiki-updating].
