Diafine is a two step process. It is great for beginners because it is not terribly temperature sensitive and the process is the same regardless of  the speed of your black and white film.

Once you are in the dark, open the canister with the bottle opener and cut the tab off the film to straighten the edge.

Wind the film onto the reel. I have two short videos that will explain the two main options and the basic process.

The plastic reel is placed on a spindle that creates a light tight barrier for the film.

The Hewes Reel does not have a spindle. It is just placed into the metal container.

Now that your film is loaded, you can bring it out of the darkroom or bag. At this time you will follow the directions provided with your chemicals.

The general directions for Diafine are: Three minutes in part A with agitation for ten seconds each minute. Drain part A back into container A. Repeat steps above with Part B.

Rinse and then fix according to the directions. Rinse well and finish with a light wash of Photo-Flo. Hang negatives to dry in a DUST FREE place. Clothes pins work very well.

I use the plastic agitation rod during the developing process. Some people prefer to invert the tank. Experiment to see what works best for you!
