Broken URL

When I try to go to en.lichess.org/embed it gives me a blank screen.
Extension I use is ABP, but I can't determine what version of Chrome I am using.

You might be interested in lichess.org/developers instead

/embed returns JavaScript and is meant for <script> tags.

That what I was looking for, but I dug around little bit and noticed it's in lichess.org/help/contribute
Would it be possible to make these niche features more public?
