+## Docker
+
+Build and push a multi-arch image (`linux/amd64` + `linux/arm64`):
+
+```sh
+docker login registry.example.com                    # once
+export MESHBOT_IMAGE=registry.example.com/team/meshbot
+./scripts/build-and-push.sh                          # tags: latest + <git sha>
+EXTRA_TAGS="v0.1.0" ./scripts/build-and-push.sh      # add explicit version
+PUSH=0 PLATFORMS=linux/amd64 ./scripts/build-and-push.sh   # local load only
+```
+
+Run via compose (set `MESHBOT_IMAGE`, `MESHBOT_LLM_BASE_URL`, `MESHBOT_LLM_MODEL`,
+optionally `MESHBOT_DEVICE`):
+
+```sh
+export MESHBOT_IMAGE=registry.example.com/team/meshbot:latest
+export MESHBOT_LLM_BASE_URL=http://llama:8080/v1
+export MESHBOT_LLM_MODEL=llama-3.1-8b-instruct
+export MESHBOT_DEVICE=/dev/ttyUSB0
+docker compose up -d
+```
+
+The container expects `config.toml` mounted at `/etc/meshbot/config.toml` and
+persists SQLite to a named volume at `/data`. Any field can still be overridden
+via `MESHBOT_<SECTION>__<KEY>` env vars.
