First BIAB

Going to try my first BIAB going from extract brewing . Extract kits have you steep the specialty grains typically for 20 min or until 170 degrees prior to the boil. With BIAB is this still
Required or just put all the grains in the bag at the same time?

All of the grains go into the bag at somewhere around 150-56deg( depending on the recipe) and hold it at whatever the desired temp for 60 minutes at least.

You don't need to steep specialty grains, you just mash them with the base grain. The general rule of thumb is:

156F - Full Body (slight residual sweetness/extra malt character)
152F - Medium Body (balanced malt character)
146F - Light Body (dryer beer/light malt character/forward hop character)

Also, to hit these mash temps, the strike water needs to be 7-8F higher than those temps so that the temp regulates back to those temps when you dump in the grain. There are plenty of calculators online to get this number exactly right, just google search for them.

Good luck!

Thanks for the help. By brew bag came in the mail today so I'm ready to go.

I use this strike water calculator and it seems to work pretty well for me:
