README.md

Please make sure that you use the documents that match your Electron version. The version number should be a part of the page URL. If it's not, you are probably using the documentation of a development branch which may contain API changes that are not compatible with your Electron version. If that's the case, you can switch to a different version of the documentation at the available versions list on atom.io, or if you're using the GitHub interface, open the "Switch branches/tags" dropdown and select the tag that matches your version.
