RELATE validation is also available as a stand-alone script :command:relate-validate.
This runs independently of git and the web site on the content developer's
computer and provides validation feedback without having to commit and
upload the content to a RELATE site. This script can be installed by running::
In RELATE Document-Writing content for RELATE(https://documen.tician.de/relate/content.html#writing-content-for-relate)
But, in the root directory of RELATE, there is no requirements.txt file at all. Does anyone have encountered the same problem as me?
