-# Dev guide
-
-Install `task`: https://taskfile.dev/
-
-```bash
-# Generate code
-task gen
-
-# Run an example (Should take care of generating code if required)
-task example NAME=basic
-```
-
-A bunch of code lives inside `syncgen` directory. The generated code will be `s2/*.sync.go`.
-This is done so we can replicate the comments from proto without copypasta.
-
-Ensure there is no business logic inside the `syncgen` directory.
-Make sure it's just some structures and function declarations.
-
-* `syncgen/types.sync.tmpl`: Has all the parallel types from `pb/s2.pb.go`
-* `syncgen/client.sync.tmpl`: Has all the parallel client method declarations from `pb/s2_grpc.pb.go`
