+Install rust  (stable is fine) with rustup, as well as cmake. Then, compile and run aquatic:
 
 ```sh
 ./scripts/run-server.sh
 ```
 
+To print default configuration as toml, pass the "-p" flag to the binary:
+
+```sh
+./scripts/run-server.sh -p
+```
+
+Example output:
+
+```toml
+socket_workers = 1
+request_workers = 1

+To adjust the settings, save this text to a file and make your changes. The
+values you will most likely want to adjust are `socket_workers` (number of
+threads reading from and writing to sockets) and `network.address`. (Some
+documentation of the various options is available in source code file
+`aquatic/src/lib/config.rs`.) Then run aquatic with a "-c" argument pointing
+to the file, e.g.:
+
+```sh
+./scripts/run-server.sh -c "tmp/aquatic.toml"
