-# anchor-gen
-
-Generates a crate for cross-program invocations to an Anchor program from a JSON IDL.
-
-## Usage
-
-In a new crate, write:
-
-```skip
-anchor_gen::generate_cpi_crate!("../../examples/govern-cpi/idl.json");
-
-declare_id!("GjphYQcbP1m3FuDyCTUJf2mUMxKPE3j6feWU1rxvC7Ps");
-```
-
-This will generate a fully functional Rust CPI client for your IDL.
-
-More examples can be found in the [examples/](https://github.com/saber-hq/anchor-gen/tree/master/examples) directory.
-
-Note: This does not work on legacy IDLs. To migrate a legacy IDL, use `anchor idl convert idl.json`.
