+
+* `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 _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 _NetBox Docker version_ `a.b.c` to guarantee the compatibility.
+  These images are automatically built from [the `master` branch of NetBox][netbox-master].

+  It always points to the latest version of _NetBox Docker_.
+* `latest`
