If you house is listed on the MLS it will show up on Trulia with the information entered from an automatic feed. Your agent can then update the listing and add more information if necessary.
If you are not using an agent to market your house for sale, you should use "for Sale by Owner" type of sites.
Hope this answers your question!
I believe this is a question for your agent. However, to answer your question, once a property gets listed on MLS, either it pulls automatically sometime later, or the agent needs to update his/her profile and manually submit the MLS listing.
Hope that answers your question fully.
BTW, what is your home listed for and who is it listed with?

I'm not sure I understand your question, do you want to know how to market your home, how to prepare your home for sale or if you can put your home up for sale using Trulia. Give me a little
more information on what your goal is and I can give you advice on how to move forward.
