First, you should try to write everything down. If you have a twiki or internal site, organize the information and how things are done. Encourage others with experience to also document everything. This will form some of the basis for your on boarding of junior developers. If you do not have guidelines for how your code should look, how code is tested, and how code is released, get the team together and write them. Having the basics available for the juniors to learn from is incredibly helpful.
