They will give you all the info you need. If you have some specific questions, just feel free to post them, and you should get plenty of answers!
How old are your pigs? What type of food are you feeding? Veggies?--pigs should have min. 1 cup fresh veggies everyday (no iceberg lettuce/cabbage). Bell peppers are a favorit with most pigs and are high in vitamin C (which is very important that they get about 10-30mg a day). Plain pellets should be feed only. No seeds, nuts, colored bites, or corn. Those are very bad for your pig. Only use Mazuri, Oxbow, or KM's pellets. The rest of the brands have addatives that are very bad for your pig. Also, a quality timothy hay should be available to your pig all day/night. They should have unlimited amounts. This helps aid digestion and keep their teeth filed down. Bedding: No Cedar! Kiln-dried pine, Aspen, Carefresh, yeasterday's News. Fleece are a few that are safe to use. NO seed and nut, or yougurt treats----those are bad for your pig to!
Ok, that was just a quick summary of some important info. Hope that helps some. But please read all the info on those web sites. I only covered a small fraction of the information that you need to know! Again, welcome and post some pictures when you can! :0)
