+## Remote Access
+
+Two approaches: mount the 9P namespace directly with `9pfuse`, or reach it over HTTP via `ollie-httpgw`.
+
+### 9P mount
+
+Because `olliesrv` speaks 9P over TCP, a remote instance can be mounted into the local namespace using `9pfuse`. Agent sessions, tools, and all other filesystem state on a remote host become ordinary local files — no special client needed.
+
+```sh
+# On the remote host:
+olliesrv start -tcp :9564
+
+# Locally:
+olliesrv mount remotehost:9564 ~/mnt/remotehost
+ls ~/mnt/remotehost      # s/, ...
+```
+
+Sessions created under `~/mnt/remotehost/s/` run on the remote host, so tool calls execute close to the remote filesystem rather than over the wire.
+
+### HTTP gateway
+
+`ollie-httpgw` translates HTTP to 9P, letting any HTTP client interact with `olliesrv` without a 9P library. It's also the backend for the web UI.
+
+```sh
+# Connect to local server:
+ollie-httpgw
+
+# Connect to remote server:
+ollie-httpgw -net tcp -addr remotehost:9564
+```
+
+See [doc/USAGE.md](https://github.com/lneely/ollie/blob/main/doc/USAGE.md) for full details on the gateway and web UI.
+
+### Container
+
+A `Containerfile` is included (at the monorepo root) for running a self-contained remote server:
+
+```sh
+podman build --network=host -t olliesrv .
+podman run --network=host -e ANTHROPIC_API_KEY=$ANTHROPIC_API_KEY olliesrv
+```
+
+Then mount locally or point httpgw at it:
+
+```sh
+olliesrv mount localhost:9564 ~/mnt/container-ollie
+# or
+ollie-httpgw -net tcp -addr localhost:9564
+```
+
