Has the seed shell come off?
If it's having trouble coming off, spray it with a good amount of water, wait, and you'll see it comes off without problems...
In the first weeks, it needs light, water but not too much (let it dry between one watering and the next) and humidity.
As
@Growstick said, you can use a stimulant and later a fertilizer.
If the seedling stretches too much, you can add soil to cover the stem...
