 Run Pronterface or Pronsole from the binary files or from source calling pronterface.py for the GUI version and pronsole.py for the commandline version.
 
-Run 'release_windows.bat' when ever you make changes or updates. With each new run it will compile the binaries and update all involved libraries in the virtual environment if needed. Delete the virtual environment if you have problems with it. Use 'git submodule update --init --recursive' for updating the submodule

+`%LocalAppData%\Microsoft\WindowsApps\wt.exe --title Pronsole %USERPROFILE%\Downloads\pronterface-test\pronsole.exe`
+You need to adjust the path to your location of pronsole.exe.
