 OpenSSE uses Google's [gRPC](http://grpc.io) as its RPC machinery.
 On Linux, there is, for now, no other way than installing gRPC from source.
 The procedure is described [here](https://github.com/grpc/grpc/blob/master/BUILDING.md).
+Note that OpenSSE has been tested with gRPC v1.34.
 
 ### Installing RocksDB
 
 OpenSSE uses Facebook's [RocksDB](http://rocksdb.org) as its storage engine. See the [installation guide](https://github.com/facebook/rocksdb/blob/master/INSTALL.md).
+Note that the build system currently used by this project does not support static builds of RocksDB. If you see linker errors involving compression libraries (`libzstd`, `libz4`, `libsnappy`, ...), it probably comes from OpenSSE linking against RocksDB's static library.

-In this project, CMake can also be used to configure the cryptographic toolkit.
