How do you add a team you're part of or manage?

Hey, how does all this work? Is all the information being sourced in the backend by the owners of the website or do users have the ability to update their own teams and team performances to showcase on this website?
Bit perplexed so just asking,

Would appreciate any and all replies.

it's all done by staff manually.

we try to cover all notable tournaments in every region so if you have a specific request, feel free to suggest it.
