[Feature Request]: Add Intro to Battles (Poker) page

[StevenWeathers]

Description

It would be nice to have an "elevator pitch" intro on the Battles (Poker) page that helps sell what poker planning is and how Thunderdome's offering aids in that process especially with remote teams.

Describe the solution you'd like

It could be a small intro that leads to another more in depth guide from a "Learn more" call to action.

Describe alternatives you've considered

Relying on the current landing page to intro the poker planning feature.
