 ## Building
 
-You need a valid rocksdb library somewhere your linker can find it.
+You need a valid rocksdb library in the root of this project so your linker can find it.  It is recommended to use a recent version of rocksdb, tested with 
+
+- facebook-rocksdb-v5.12.4 (https://github.com/facebook/rocksdb/archive/v5.12.4.tar.gz)
+
+Note: Windows rocksdb will work and recommendation is to use vcpkg to build rocks first, and copy your rocksdb-shared.dll into the root of the parent project.
+
+## Testing
+
+> dub test
+
+will launch a benchmark, and should be enough to convine one of the functionality and performance.
 
 ## Example

-import rocksdb;
-import std.conv : to;
-
 auto opts = new DBOptions;
 opts.createIfMissing = true;
 opts.errorIfExists = false;

 // Delete a value

 // Add values in bulk
