+Quick example of how to use the package:
+
+```
+from egi_pynetstation import NetStation
+# Set an IP address for the computer running NetStation as an IPv4 string
+IP_ns = '10.10.10.42'
+# Set a port that NetStation will be listening to as an integer
+port_ns = 55513
+ns = NetStation(IP_ns, port_ns)
+# Set an NTP clock server (the amplifier) address as an IPv4 string
+IP_amp = '10.10.10.51'
+ns.connect(ntp_ip=IP_amp)
+# Do whatever setup for your experiment here...
+# Begin recording
+ns.begin_rec()
+# You can now send events; this one just says "HIYA" and automatically
+# marks the time for you
+ns.send_event(event_type="HIYA")
+# You can include a data dictionary; perhaps you have a dog stimulus
+my_data = {"dogs": "fido"}
+# Send this data with the event type of "STIM"
+ns.send_event(event_type="STIM", data=my_data)
+# Occasionally resync the clocks, perhaps after each trial
+ns.resync()
+# With the experiment concluded, you can end the recording
+ns.end_rec()
+# You'll want to disconnect the amplifier when your program is done
+ns.disconnect()
