GitHub no longer serves file contents as plain HTML on the website. JavaScript is now required to render them. To get raw file contents without JS, convert the URL as follows:
https://github.com/<USER>/<REPO>/blob/<BRANCH>/<PATH>
https://raw.githubusercontent.com/<USER>/<REPO>/<BRANCH>/<PATH>
<PATH>
refers to the full path for a file within subdirectories. Should the
file appear in the base of the repository, the value is just the file name.
The release pages on GitHub require JavaScript to load, but the format is predictable. To download files directly, construct the URL in the following format:
https://github.com/<USER>/<REPO>/releases/download/<TAG>/<FILENAME>
The value for FILENAME
may not be obvious.
