This is a quick tip for Gemini capsule authors that use Amfora as their Gemini browser.
Amfora can open local gemtext files, but it is not obvious how to do so because simply providing the file name as an argument results in an error.
Instead, Amfora understands the file:// protocol, so one should provide the full path to the file they want to view. Below is an example:
$ amfora file:///home/jara25/path/to/index.gmi
Note that there are three forward slashes after the colon and not two. Recall that an absolute path begins with /, so it also needs to be part of the URL.
