 **Welcome to the Type Level TypeScript Workshop!**
 
+🚧 the textual version of the workshop is still a Work In Progress 🚧
+
 In this course and workshop we hope to take your TypeScript skills from intermediate to **advanced**, and even make a real **TypeScript Wizard** of you! We will start by demonstrating that the type system of TypeScript is much more than simple type annotations: it's actually a full fledged **programming language** in itself! Once you know how to program with types, everything becomes possible. You will no longer feel like your ability to write the abstractions you need is restrained by the type system.
 
 Types are great for many reasons. They **document** the APIs you create, They make developers more **proficient** by providing them smart suggestions as they type and by catching mistakes and typos. The more the type system knows about your code, the better it is at helping you!
