In this tutorial I give a broad overview of what serialization and deserialization are, how they work, and how you might implement it. I give two specific code examples, one in Java and one in C++, and I list some useful libraries to help with the serialization process. I recommend serializing the data to a json format, and including a version system to ensure that when you update software and the save process changes, users can safely upgrade there files.
