* add basic tutorial, re-export client stuff in HighLevel.Generated * add a relative link in README.md * forgot to document the language extensions * cabal file fixup * more context to compile-proto-file * haskell syntax highlighting in markdown * link to gRPC official tutorials for basic concepts * add a note on how to build the examples * prominent notice of required gRPC version * fix typo * do some error handling, show how to run the example executables * use mapM
