+## Docker tags
+
+The official `netdata/netdata` Docker image provides the following named tags:
+
+* `stable`: The `stable` tag will always point to the most recently published stable build.
+* `edge`: The `edge` tag will always point ot the most recently published nightly build. In most cases, this is
+  updated daily at around 01:00 UTC.
+* `latest`: The `latest` tag will always point to the most recently published build, whether it’s a stable build
+  or a nightly build. This is what Docker will use by default if you do not specify a tag.
+
+Additionally, for each stable release, three tags are pushed, one with the full version of the release (for example,
+`v1.30.0`), one with just the major and minor version (for example, `v1.30`), and one with just the major version
+(for example, `v1`). The tags for the minor versions and major versions are updated whenever a release is published
+that would match that tag (for example, if `v1.30.1` were to be published, the `v1.30` tag would be updated to
+point to that instead of `v1.30.0`).

 ## Health Checks
