In Pokemon Yellow, you can only start out with Pikachu. Your Pikachu will follow you everywhere and if you look at it, it will show you how it feels about having you as a trainer. Pokemon Yellow is the same Pokemon World as Red and Blue, except that on Route 19 there is a new house that doesn't exist in the Red and Blue Versions.

Pallet Town
Go to the PC in the room you start out in and withdraw the potion. Go down the stairs and out of the house. Go to your right, up and into the patch of grass. Professor Oak will come to stop you. Then you will both be attacked by a wild Pikachu. Professor Oak captures the Pikachu and then brings you back to his lab. Professor Oak will tell you to choose a Pokemon. When you go to take the Poke Ball off the table, your rival pushes you out of the way and takes it. Professor Oak then gives you the Pikachu he just caught. When you try to leave the building, your rival will challenge you. Use a combination of growl and thundershock to beat his Eevee. Use the potion if you need it. Then leave the building and go up Route 1.

Route 1
Go up Route 1 to Viridian City. Train your Pokemon against wild Pokemon on your way there.

Viridian City

When you have caught and trained enough of your Pokemon, go battle your rival who is waiting for you on Route 22. I would train the Pokemon used in battle to level 10 before going to your rival. Train them in Viridian Forest against Metapod. Good Pokemon to train are Caterpie, maybe a Nidoran, and of course your Pikachu. Your rival will have a L9 Pidgey and then a L8 Eevee. If you beat him here and beat him at Professor Oak's lab, his Eevee will evolve into Jolteon. If you loose here and lost at Professor Oak's lab, it will evolve into Vaporeon.
