-# Shibarium heimdall node Dockerfile

-# Uses the standard cometbft-node pattern from vibe-node.
+# Shibarium heimdall consensus node — BUILT FROM SOURCE.
+#
+# shibaone publishes NO heimdall docker image (only source + release .deb config
+# packages), so we cannot `FROM shibaone/heimdall:<tag>` — that tag does not exist
+# on any registry. Instead we mirror the upstream shibaone/heimdall Dockerfile
+# (`make install`) but clone the pinned tag, then layer the vibe-node CometBFT
+# bootstrap entrypoint (init.sh + cometbft-common.sh).
 #
 # Build args:
-#   CL_IMAGE     - base heimdall image (default: shibaone/heimdall)
-#   CL_VERSION   - heimdall version tag
+#   CL_REPO     - heimdall source repo  (default: https://github.com/shibaone/heimdall)
+#   CL_VERSION  - heimdall version tag  (passed by the template, e.g. v1.0.7-bone)
 #
-# The entrypoint is init.sh which sources cometbft-common.sh and bootstraps
-# the node before exec'ing heimdalld start.
+# `make install` puts heimdalld + heimdallcli on /go/bin (already on PATH).
+# The entrypoint is init.sh: it sources cometbft-common.sh, runs heimdalld init
+# --chain shibarium, fetches the heimdall-109 genesis from GENESIS_URL, sets the
+# shibarium seeds/persistent_peers, then exec's `heimdalld start --rest-server`.
