 ## Diagnostics
 
-A **diagnoser** can attach to your benchmark and get some useful info. There is a separated package with diagnosers for Windows ([BenchmarkDotNet.Diagnostics.Windows](https://www.nuget.org/packages/BenchmarkDotNet.Diagnostics.Windows/)). The current Diagnosers are: *GC and Memory Allocation* (`MemoryDiagnoser`) and *JIT Inlining Events* (`InliningDiagnoser`).
