Most of the resources needed to complete solutions using the IBM Watson IoT Platform can be found in the official documentation at the following link: https://console.bluemix.net/docs/services/IoT/index.html#gettingstartedtemplate. There are also many recipes published by the community that uses IBM Watson IoT, and these are available at the developerWorks Recipes website here: https://developer.ibm.com/recipes/tutorials/category/internet-of-things-iot/.
It's also very helpful to understand how to upload a project to a GitHub repository and how to create a delivery pipeline to automatically build, test, and deploy an application whenever a new change is pushed to the repository. Doing this is not within the scope of this book, but it's still a really good practice to use.
