First you must have an account on SteamGifts, the next requirement is to do one of these options:

• Spread my website in forums and communities related to PC games, but make sure you comply with the rules of where you publish my website. I will check if it generates a minimum number of visits and that these are legitimate, I hope you understand that it does not help me to put my website in a forum with 0 visits.
• Make a contribution of at least 5€ to pepeizq’s deals in any bundle available in Humble Bundle, I will need to know in which bundle you have contributed, the exact amount of contribution and the day of purchase of the bundle.

After having completed one of the options, you must apply to the private Steam group. And finally contact me with the following information:

• I need to know what requirement you have done.
• I also will need to know your Steam user to approve it in the group.

I want to warn you that the process of adding you to the group is not fast, although I authorize you at the moment, SteamGifts takes hours to update the users of the group with what you must wait to be able to enter the giveaways.
