Yourls link to environment variables for configuration seems to be broken

[chjno]

docs/yourls/README.md

Line 96 in aaf4aad

The YOURLS instance accepts [a number of environment variables for configuration](https://yourls.org/#Config).

The Yourls docker image readme links to https://yourls.org/#Config for more information regarding configurable environment variables. However, this link just leads to the Yourls homepage. I'm guessing the link should direct to https://yourls.org/docs/guide/essentials/configuration.

Good catch, thanks for reporting @chjno.
Indeed, our documentation system has changed recently.
You are correct on where it should point.
Would you like to submit a pull request to fix this?
The file that needs to be corrected is this one: https://github.com/docker-library/docs/blob/master/yourls/content.md
If you do so, just tag me on the PR.
