+Datatypes generated from the protobuf schema
+
+
+## Development
+
+This project consists of a Haskell package named `semantic-proto`. The library’s sources are in [`src`][].
+
+Development of `semantic-proto` is typically done using `cabal v2-build`:
+
+```shell
+cabal v2-build # build the library
+cabal v2-repl  # load the package into ghci
+cabal v2-test  # build and run the doctests
+```
