-## aquatic_udp
+## Installation prerequisites
 
-Aims to implements the [UDP BitTorrent protocol](https://libtorrent.org/udp_tracker_protocol.html), except that it:
+- Install rust with rustup (stable rust is recommended). 
+- Install cmake with your package manager.
+- Clone the git repository and refer to the next section.
+
+## Run
+
+The command line interfaces for `aquatic_udp` and `aquatic_ws` are identical.
+To run the respective tracker, just run its binary. You can also run any of
+the helper scripts, which will compile the binary for you and pass on any
+command line parameters.
+
+To run with default settings:
+
+```sh
+./scripts/run-aquatic-udp.sh
+```
+
+```sh
+./scripts/run-aquatic-ws.sh
+```
+
+To print default settings to standard output, pass the "-p" flag to the binary:
+
+```sh
+./scripts/run-aquatic-udp.sh -p
+```
+
+```sh
+./scripts/run-aquatic-ws.sh -p
+```
+
+To adjust the settings, save the output of the previous command 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
+`address` under the `network` section (listening address). This goes for both
+`aquatic_udp` and `aquatic_ws`. Some documentation of the various options is
+available in source code files `aquatic_udp/src/lib/config.rs` and
+`aquatic_ws/src/lib/config.rs`.
+
+Then run the binaries with a "-c" argument pointing to the file, e.g.:
+
+```sh
+./scripts/run-aquatic-udp.sh -c "/path/to/aquatic-udp-config.toml"
+```
+
+```sh
+./scripts/run-aquatic-ws.sh -c "/path/to/aquatic-ws-config.toml"
+```
