Become a part of vim-polyglot community

[sheerun]

Hey @tpope

Thank you for an awesome syntax for vim! I'd like to discuss something with you:

1. Long time ago I've selected your syntax plugin as a part of vim-polyglot language pack. It is regularly updated and developed for more than 2 years now. I'd like to ask you to include link to it in your README, so all language packs and vim-polyglot can gain popularity as a community :) I'm sending a pull-request with one possible reference, but maybe you want to write one by yourself? Vim-polyglot already lists and links to your plugin.
2. Vim-polyglot is an open source project, but I'd like to make it a community effort. Maybe you'd like to become a contributor to it? You'd have commit access so you could fix any issues vim-polyglot introduces, release updates, and help other language packs authors. To be clear vim-polyglot just bundles your package, so I’m not asking to drop your repository, just contribute to another one :)

Thank you for considering both requests.

This is the first pull-request I make on your repositories, so if you deny this one, I'll refrain from creating pull requests on your other language packs that are part of vim-polyglot.
