-# Macros
-
-Rust's macro system is very powerful, but also kind of difficult to wrap your
-head around. We're not going to teach you how to write your own fully-featured
-macros. Instead, we'll show you how to use and create them.
-
-If you'd like to learn more about writing your own macros, the
-[macrokata](https://github.com/tfpk/macrokata) project has a similar style
-of exercises to Rustlings, but is all about learning to write Macros.
