Basics

First, read the Hedera Documentation. This will be your main reference for all transaction types, network concepts, tools, and general information about how to interact with Hedera. It is critical that you understand all the different API's available to you. They are the core tools in your toolbelt.

As with most things in the web3 space the majority of things you build and tooling available will be using Javascript (preferably TypeScript). It is recommended you have a good understanding on general Javascript workflows, and are proficient in at least one of the major web frameworks (Angular, React, Vue, etc).

Support for other languages is available (you can find the various Hedera SDK's here) but Javascript is the most popular with the widest variety of tooling.

Game developers can check out the Game Development section for more specialized tooling, though it is still recommended they read the rest of this guide as well.
