From 7ef5d754f73bf875d2eb09f698c69f2a09d701e5 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Fri, 3 Dec 2021 00:57:47 +0300 Subject: docs: ARC: Improve readability There were some things which made rendered document look not very elegant. That was because: 1. Numbered lists were formatted in more of Markdown way rather than true reStructuredText and so were displayed as a plain text with leading numbers. Well, moreover numbered lists were not needed as in all cases we were just listing a couple of options w/o any intention to follow any particular order, so a simpler unordered list fits better and looks cleaner. 2. URL's of external resources were added as they are (which is OK in a plain text, but make not much sense in a HTML where we may use more human-friendly link names with URL's hidden. 3. Some URL's had trailing slashes which were not really needed Fix all items from above!
