 As always, build the STL from your branch and run the tests:
 ```

 You can replace `bark` with any descriptive name you like. Add these before the `"-link"` option in the command line
 and recompile. Example:
 ```
-C:\STL\out\x64>cl "C:\STL\tests\std\tests\GH_XXXX_meow\test.cpp" [... more arguments ...]
-"-FeC:\STL\out\x64\tests\std\tests\GH_XXXX_meow\Output\02\GH_XXXX_meow.exe" /Zi /Fdbark.pdb "-link"

 [... more arguments ...]
 ```
 
 You can now start debugging the test via:
 ```
-devenv "C:\STL\out\x64\tests\std\tests\GH_XXXX_meow\Output\02\GH_XXXX_meow.exe"
-       "C:\STL\tests\std\tests\GH_XXXX_meow\test.cpp"

+       "C:\Dev\STL\tests\std\tests\GH_XXXX_meow\test.cpp"
 ```
 
 However, this might not work right away, as Visual Studio may complain about a missing `msvcp140_oss.dll`. The reason
 is that the STL builds those and other DLLs itself and we should under no circumstances overwrite the installed ones.
 If you are testing one of the configurations with dynamic linkage (`/MD` or `/MDd`) the easiest solution is to add the
 build folder to your path:
 ```
-set PATH=C:\STL\out\x64\out\bin\amd64;%PATH%
+set PATH=C:\Dev\STL\out\x64\out\bin\amd64;%PATH%
 ```
