 `pi-stats` reads stats from a Raspberry Pi's VideoCore processor and writes them
 to stdout using InfluxDB's line protocol[0].
 
-## Usage
+## Installing
+
+To have everything installed for you, run `make all`. You'll likely need root
+privileges.
+
+To install `pi-stats` manually:
 
 1. Build the `pi-stats` binary with `make` (or `make install` and skip step #2)
-2. Install inside `/usr/local/bin`
-3. Copy `pi-stats.service` to `/etc/systemd/service`
-4. Copy `pi-stats.conf` to `/etc/logrotate.d`
-5. Enable and start the `pi-stats` service: `systemctl enable pi-stats` and 
-   `systemctl start pi-stats`, respectively
+2. Copy `pi-stats` to `/usr/local/bin`
+3. Copy `pi-stats.service` to `/etc/systemd/service/` (or `make install-service`)
+4. Copy `pi-stats.conf` to `/etc/logrotate.d/pi-stats` (or `make install-logrot`)
+
+Once you've installed `pi-stats`, make sure to enable and run the service with
+`systemctl enable pi-stats` and `systemctl start pi-stats`, respectively. Again,
+you'll likely need root privileges.
+
+# Configuring
 
 By default, `pi-stats` reads from VideoCore once per second. This can be
 configured with the `-s` flag, which is the number of seconds between reads.
 
+# Usage
+
 The stats are written to `/var/log/pi-stats.log`, which can then be parsed by
 Telegraf[1].
