-## Cap'n Proto schema
-
-The compiler uses a Cap'n Proto schema to serialize/deserialize module information.
-Occasionally, the schema needs to change. After modifying `compiler-core/schema.capnp`
-you need to re-generate `compiler-core/generated/schema_capnp.rs`. To do that,
-[install Cap'n Proto](https://capnproto.org/install.html) and un-comment appropriate lines
-in `compiler-core/build.rs`. Then you should be able to re-generate that file with:
-
-```sh
-cd compiler-core
-cargo build
-```
