 ### The TL;DR:
-
+This is the ideal setup for a project that wants to keep their C-API within the main crate:
 - [Create][diff-1] a `capi.rs` with the C-API you want to expose and use
   ~~`#[cfg(cargo_c)]`~~`#[cfg(feature="capi")]` to hide it when you build a normal rust library.

+If you plan to keep the bindings as a separate crate and do not need to autogenerate the headers you may just [populate Cargo.toml][diff-5]:

+- Set the entry in `package.metadata.capi.header.generate` to `false`.
+- Optionally override the path to the header to a custom one instead of the default one.
