Check the original post in the thread.

Basics: Post a list, or surf around and look at what people have and make offers. Usually person with lowest "rep" goes first. If trade is good post a thank you here so public knows good feedback. Many keys are from bundles so discounted to begin with.

Here you can trade for gifts that are in your Steam Inventory and for unused codes to redeem games on GOG, Steam, Uplay, Origin, Humble Bundle, Desura, etc... Usually gifts in the Steam Inventory are more valuable, because you can use the trade system from there which is safer than trading for codes via chat or PM that can't be verified if they were used or not, and the gifts don't expire if they are kept in your Inventory. Just read the first post to understand better, and if you have more questions, ask away ;)

By the way, bundle games has less value than non-bundle games, unless you want to trade many bundle games for 1 non-bundle game.

Just remember, games in your Steam Library can't be traded (they're already activated in your account), only the games in your Steam Inventory, and keys to redeem games on different services can be traded.

Check your PMs sir, as I've sent you a fully detailed description of what has to be done to enter our Trading World with our Lovely Trading Community (more like a Family actually) :)

Have fun!
