 ## Image versions
 
+This image is based on the popular [Alpine Linux project][1], available in [the alpine official image][2]. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.
 
-### `latest`
-
-Latest version of restic.
+This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use [musl libc][4] instead of [glibc and friends][5], so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See [this Hacker News comment thread][6] for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.
 
 
 ### `X`
 
-Latest version of restic `X` branch.
+Latest tag of `X` restic's major version.
 
 
 ### `X.Y`
 
-Latest version of restic `X.Y` branch.
+Latest tag of `X.Y` restic's minor version.
 
 
 ### `X.Y.Z`
 
-Concrete `X.Y.Z` version of restic.
+Latest tag of a concrete `X.Y.Z` version of restic.
+
+
+### `X.Y.Z-rN`
+
+Concrete `N` image revision tag of a restic's concrete `X.Y.Z` version.

+Once build, it's never updated.
