Where do I find information on how to convert my train to DCC? 

Be more specific.
There are different decoder companies and may different type of locos, including scale of loco.
You gave us essentially zero info.

Will you control with DC or DCC?

How much experience and knowledge of electronics/soldering do you have?
Many times a DCC install is not plug and play.

Do you want sound also? That will usually make the install more complicated at times.
Never make assumptions with DCC. It will bite you at times.

The Internet is loaded with all kinds of DCC info. You just need to search and do  lot of reading.  The step from DC to DCC is quite a step if you want to do an install yourself.
Buying a DCC equipped loco and getting it to run is somewhat easier, ok, for various values of easy.
