            Hi ! I am a bot developed by Anatole ! For the moment, you can use those commands :\n
            ° !info - to get all the informations (but you already knew that)\n
            ° !gif whatever you want - This will select a random GIF based on the keyword(s) you asked for

            I also post a welcome GIF when a new channel is created!

            Anatole and I hope that our work will be useful to you !
