Hi @[deleted] Welcome to the Trello world.
I highly recommend to you and anyone new to Trello to check out this free course offered by Atlassian:

When you say group some categories can you explain a little more.
There are several ways you can group cards by category, by using lists as categories, using labels for categories or using custom fields for categories.
If you can explain what you are looking to achieve, I will be able to be more specific.
