-# Knit
-
-This is a very simple tool that produces Kotlin source example files from a markdown document that includes
-snippets of Kotlin code in its body. It is used to produce examples for 
-[coroutines guide](../docs/coroutines-guide.md) and other markdown documents.
-It also includes links to the documentation web site into the documents.
-
-## Usage
-
-* In project root directory do:
-  * Run `./gradlew knit`
-* Commit updated documents and examples
