Yeah I saw that after Arthmoor pointed it out. But those instructions should be in a more prominent place - such as the mod's main description. There's no reason to have it separated.
A mod's instructions and detailed information don't belong there cluttering up the page and making a mess. That's what readmes are for, and why Nexus gave us a handy place to upload them and even provided a direct link to them.
I personally take it as a sign of poor quality when I run into a mod entry where the entire readme is posted as a description. That's just plain unprofessional in my eyes. Though it isn't always a case of poor quality, it's just one thing I look for. Plenty of mods on Nexus have actual descriptive descriptions of what the mod is, features it may have that are new, and perhaps some promotional material linked to that.
