+## Intro
+
+HDL is a way to describe hardware and you absolutely need to understand what it does, why, and how to use it in order to move further in your learning journey.
+
+This video serves as an introduction for beginners to get your head around HDL for the first time and implement your first custom logic through a simple example on Xilinx tools.
+
+## Prerequisites
+
+- Know the **basics** of "programming".
+- Know what a logic gate and a register is.
+- If you want to do the exmaple : Install Vivado.
