Getting Started
Welcome to the Flow Developer Portal
Before starting your journey on Flow we recommend reading the Flow Primer where you will get a quick introduction to how the Flow blockchain works. It will be easier to understand the concepts in these tutorials if you have an idea of how Flow works.
