 ## Docker
+Data is stored at `/home/monero-lws/.bitmonero/light_wallet_server` by default,
+and be modified by `--db-path` at runtime.
+
+### Latest Stable Release
+Docker image for latest stable release can be fetched via:
+
+  * `docker pull ghcr.io/vtnerd/monero-lws`
+  * `docker pull vtnerd/monero-lws`
+
+Users of this tag should never expect a DB migration issue, provided they never
+"downgrade" to a prior major version.
+
+### Supported Releases
+Docker images for `0` and `0.3` are provided. The major number refers to
+backwards incompatible DB changes, and the minor revision refers to new features
+that could cause instability. Stability minded users can use these tags while
+they are still listed as officially supported here in the README or on the
+Docker overview page.
