+## Conclusion
+
+Thanks for reading *The Definitive Guide to GTFS-realtime*. I wrote this
+book with the intention of providing a comprehensive guide to getting
+started with consuming real-time data using the GTFS-realtime
+specification.
+
+One of the biggest advantages GTFS-realtime has over other real-time
+specifications or services (such NextBus or SIRI) is that it is designed
+to complement GTFS feeds by sharing a common set of identifiers.
+
+On one hand, GTFS-realtime is very straightforward, as it provides only
+three different types of messages (service alerts, vehicle positions and
+trip updates), but there are a number of complexities involved in
+getting started with both consuming and producing GTFS-realtime feeds,
+such as setting up Protocol Buffers to read feeds, or understanding the
+intent of trip updates.
+
+The key takeaways from this book are:
+
+* The different types of real-time data available in GTFS-realtime feeds.
+* How to read data from a GTFS-realtime feed.
+* How to apply the data you read from GTFS-realtime feeds to your own applications.
+* They main concepts behind producing and publishing your own GTFS-realtime feeds.
+
+If you have enjoyed this book, please share it or feel free to contribution improvements or changes as necessary.
