Provide a better migration docs for Atom IDE #139
Description
The current docs on https://ide.atom.io are not very detailed. They only say to install atom-ide-ui and ide-* packages. However, there are some potentially confusing problems that are not addressed there.
After installing atom-ide-ui, Atom asked me to disable linter package and I did that. However, I still have linter-ui-default package enabled, should I disable it as well? Could it be done automatically as well?
Some older linter-* packages seem to have linter package as their dependency, because Atom is asking me now to enable linter package, when I use e.g. linter-erb, linter-elixirc or linter-coffeelint. The docs could describe what to do in such case, e.g. if I should report the issue to the maintainer of such package or how to fix it, so that I can prepare a PR.
It's also a bit confusing what ide-* packages actually provide, e.g. if I install ide-typescript package, which is supposed to handle JavaScript as well, do I still need linter-eslint package? Will ide-typescript package correctly handle experimental JS syntax provided by Babel that is not handled by TypeScript yet? Can I uninstall language-babel package now? And so on...
Another thing is the hyperclick feature. I already had hyperclick package installed - should I uninstall it after installing atom-ide-ui? If I do uninstall it, Cmd + click doesn't really do anything in JS files anymore. I'm not sure if it's a limitation of ide-typescript package though or if I should keep hyperclick package installed. Also, the default Cmd + click shortcut on Mac conflicts with the multiple cursors shortcut provided natively by Atom.
