 ## How to use `C2CS`
 
-To generate C# bindings for a C library you need to install and use the `CAstFfi` tool and setup a couple configuration files. See the [`helloworld`](../src/cs/examples/helloworld/) example projects for an example.

The extracted information _**does not contain any source code**_; it is purely meta data about the bitwidth and names of functions, structs, enums, typedefs, etc.
 2. `cs`: (NOTE: now just the main `c2cs` program!) Reading one or more previously generated C abstract syntax tree `.json` files to generate C# code for the specified target platforms.
 
 This allows the `ast` program of `C2CS` to run and extract the information for the target platforms with restrictive system headers. The resulting `.json` files of the C abstract syntax trees can be moved to any operating system to generate the C# code for multiple target platforms at once using the `cs` program of `C2CS`.
