+# This will scrape the whitelisted bridges in the current state (port 3000) and the PR state (port 3001) of
+# RSS-Bridge, generate a feed for each of the bridges and save the output as html files.
+# It also replaces the default static CSS link with a hardcoded link to @em92's public instance, so viewing
+# the HTML file locally will actually work as designed.
