@@ -12,18 +12,29 @@ To run the program, simply run it as follows:
 qdbus-prettifier <in-file> [out-file]
 ```
 
-## Building
+If `<in-file>` is defined as `-` this tells the program to read from `stdin`
+allowing input to be piped. If the `[out-file]` option is omitted then output is
+sent to `stdout`.
+
+For more information, check out the `-h` option.
+
+## Building & Installation
 
 To compile the program, install the Rust suite, namely the compiler and Cargo.
 Once installed you can run `cargo build --release` to generate a release build
 of the project which will be found at `target/release/dbus-prettifier`.
 
-To install you can use the `install` command as follows:
+To install the program you can use the `install` script. By default this will
+install to `/usr/local`, but this can be changed by setting the `PREFIX`
+variable prior to the command. For example:
 
 ```console
-install -Dm755 target/release/dbus-prettifier /usr/local/bin
+PREFIX=/usr ./install
 ```
 
+Similarly, to uninstall simply run the `uninstall` script. It uses the same
+`PREFIX` variable.
