Important legal question

I know F7 is licensed under MIT license.
I downloaded the zip of F7 from github, I deleted all files, including the license file, and just need package/core distribution.
Do I need to include license file in the package/core directory that I use? or not needed???

I’m just a user like you. But the MIT license allows you, unlike the GPL, to copy the code and “make it yours”, so you do not need to include it.

EDIT: but it does not hurt in the about section to add a thanks to Framework7 :wink:

Yes, you can removed License and modify original code on your own
