 opened in user-mode, but not changing the user after startup would retain read
 permissions to the private key.
 
+Building
+--------
+
+Set up a Cargo build environment, then simply run
+```sh
+cargo build
+```
+to create a debug build or
+```sh
+cargo build --release
+```
+to create a release build.

 Starting
 --------
 
 Sheldon Director look for a config file in `/etc/sheldond.conf`. If you want to
-change this, pass an alternative path on startup like so:
-
-An example start can look like this:
-```sh
-sudo ./sheldond -c ./sheldond.conf
-```
+change this, pass an alternative path on startup using the `-c` parameter.
+Use `-h` to get a list of all supported command line arguments.
 
 An example config file can be found in this repository in `doc/sheldond.conf`.
+Use it to serve the content of the `doc/` directory on localhost:
+```
+sudo ./target/debug/sheldond -c ./doc/sheldond.conf
+```
+Try connecting to `gemini://localhost` via your favorite Gemini client!
+
+Note: This sets the user to `nobody` and the group to `nobody` as well. This
+naming scheme is not consistent for all Unix systems... Try changing the group
+name to `nogroup` if the software fails to start.
 
 Why "Sheldon Director"?
