+## Building Library
 
 The `InvokeBuild` module is utilized to automate building the library and publishing the module (both pre-release on GitHub and to the PS Gallery).
 
 The `build.ps1` script is at the root of the project. The `build.library.ps1` hosts the dotnet code used to compile the library itself.
 
-In the main build script, the supported Configurations: Debug, Release, and Prerelease. _The last two are only used by the maintainers._
+The `build.ps1` script, the supported Configurations: Debug, Release, and Prerelease. _The last two are only used by the maintainers._
 
 To build the library for debugging or local testing, simply run the following command at the root of the project:
 
 ```powershell
 Invoke-Build -File .\build.ps1 -Configuration Debug
 ```
 
+The module having a DLL library loaded will mean each time you import the module into a PowerShell session you will need to close and restart a fresh session to do the build again.
