Lesson creators can choose a set of conditions they wish to apply to their content. This allows other users to know how they can use your material outside of LearnHub, if at all.
Check out the following videos for a entertaining explanation about Creative Commons:
Attribution.
You let others copy, distribute, display, and perform your copyrighted
work — and derivative works based upon it — but only if they give
credit the way you request.
Noncommercial.
You let others copy, distribute, display, and perform your work — and
derivative works based upon it — but for noncommercial purposes only.
No Derivative Works. You let others copy, distribute, display, and perform only verbatim copies of your work, not derivative works based upon it.
Share Alike. You allow others to distribute derivative works only under a license identical to the license that governs your work.
Selecting a LicenseAttribution - NonCommercial - ShareAlike



This license lets others remix, tweak, and build upon your work
non-commercially, as long as they credit you and license their new
creations under the identical terms. Others can download and
redistribute your work just like the by-nc-nd license, but they can
also translate, make remixes, and produce new stories based on your
work. All new work based on yours will carry the same license, so any
derivatives will also be non-commercial in nature.
Attribution - NonCommercial

This license lets others remix, tweak, and build upon your work
non-commercially, and although their new works must also acknowledge
you and be non-commercial, they don’t have to license their derivative
works on the same terms.
Attribution - NonCommercial - NoDeriv(atives)


This license is the most restrictive of our six main licenses, allowing
redistribution. This license is often called the “free advertising”
license because it allows others to download your works and share them
with others as long as they mention you and link back to you, but they
can’t change them in any way or use them commercially.
Attribution
This license lets others distribute, remix, tweak, and build upon your
work, even commercially, as long as they credit you for the original
creation. This is the most accommodating of licenses offered, in terms
of what others can do with your works licensed under Attribution.
Attribution - ShareAlike

This license lets others remix, tweak, and build upon your work even
for commercial reasons, as long as they credit you and license their
new creations under the identical terms. This license is often compared
to open source software licenses. All new works based on yours will
carry the same license, so any derivatives will also allow commercial
use.
Attribution - NoDeriv(atives)

This license allows for redistribution, commercial and non-commercial,
as long as it is passed along unchanged and in whole, with credit to you
