UK Tier 1 Global Talent Stage 2 application

Hi I got my stage 1 endorsement letter from Tech Nation.
In the stage 2 HO application there is one section asks about "Provide additional information about your application. You do not need to provide details that you have already provided in this application"

"Select the guidance for your category of application below to read about the additional information you should provide."
here u need provide 3000 words

I dont know what information I need to give here
Your assistance would be appreciated

Regards,
ibrahim
