 # Usage
 
-Examples assume `$OLLIE` is set to the ollie mount point (default: `$HOME/mnt/ollie`).
+## Server
+
+### Start and stop
+
+```sh
+olliesrv start          # start in background (daemonizes)
+olliesrv fgstart        # start in foreground
+olliesrv stop           # stop the daemon
+olliesrv status         # check if running
+```
+
+By default the server mounts at `$HOME/mnt/ollie`. Override with `-mount`:
+
+```sh
+olliesrv start -mount /tmp/ollie
+```
+
+### TCP listener
+
+To also accept connections over TCP (e.g. for remote access):
+
+```sh
+olliesrv start -tcp :9564
+```
+
+### Debug logging
+
+Log level is controlled by `OLLIE_LOG` (default: `warn`). Set to `debug` for verbose output:
+
+```sh
+OLLIE_LOG=debug olliesrv fgstart
+```
+
+Valid levels: `debug`, `info`, `warn`, `error`. Per-subsystem overrides follow the pattern
+`OLLIE_<TAG>_LOG=debug` where `<TAG>` matches the logger's tag (e.g. `OLLIE_SESSION_LOG`).
+
+---
+
+Examples below assume `$OLLIE` is set to the ollie mount point (default: `$HOME/mnt/ollie`).
 Scripts under `s/`, `b/`, and `u/` are available directly via the mounted filesystem
 after running `mk && mk scripts`.
