Getting Following error when i run the yarn dev

@shivarajnaidu There is a way to increase the system limit and we plan to explain/mention it in the README.

@fiji-flo Do you think it would be possible to trigger something like this:

try {
  startWatcher();
} catch(err) {
  if (err.toString().include("System limit for number of file watchers reached") {
    console.log("See this Troubleshooting tip about this error....")
  }
  throw err;
}

We don't use the watcher anymore for content. But you can still run into this error in Linux because of all the various source code files that react-scripts might be keeping an eye on. So we kept a blurb about it in the "Troubleshooting" section.
