 ## I keep getting changes to tsconfig.json
 This is probably because of us keeping `files` updated with the `filesGlob` option. The reason why we do this is because the official `tsconfig.json` spec does not support `filesGlob`. Therefore we keep `files` in sync with the `filesGlob` so that your team mates can use whatever editor they prefer (sublime text, visual studio etc.).
