+    # put the "release" build somewhere to be used by swaybar
+    cp ./target/release/swaybar_info ~/.config/sway/
+
+Put the following in your `~/.config/sway/config`:
+
+    bar {
+        position top
+        # Set --netdev=<device> such that <device> is the network device you
+        # want to monitor. You can omit --netdev=<device>, but that will also
+        # cause the program to omit network traffic stats.
