> - not publicly promote or link us yet: (no tweets, blog posts or other forms of communication about Lion Web Components)
> - not publicly promote or link products derived from/based on Lion Web Components
>
> As soon as Pilot Phase ends we will let you know (feel free to subscribe to this issue https://github.com/ing-bank/lion/issues/1)
