Certainly! Developing black-and-white film can be a rewarding and satisfying process. Here are the steps and materials needed for developing the negatives:

Materials:
- Film
- Developing tank and reel
- Developer
- Stop bath (or water)
- Fixer
- Wetting agent
- Graduated cylinder
- Thermometer
- Timer
- Scissors
- Film clips
- Storage bottles

Steps:
1. Load the film onto the reel in total darkness.
2. Mix the developer and water according to the dilution instructions on the bottle and the amount of chemistry needed for your roll of film.
3. Fill the developing tank with water at the correct temperature and let sit for one minute.
4. Pour in the developer and start the timer.
5. Agitate the tank according to the instructions on the developer bottle for the required amount of time.
6. Pour out the developer and save it for reuse.
7. Rinse the film with water to stop the development process.
8. Mix the fixer and water according to the dilution instructions on the bottle.
9. Pour the fixer into the tank and agitate for the required amount of time.
10. Pour out the fixer and save it for reuse.
11. Rinse the film thoroughly with water.
12. Use a wetting agent solution to avoid water marks on the film.
13. Hang the film to dry using film clips.

For making prints in your own custom darkroom, you will also need:
- Enlarger
- Photographic paper
- Trays for chemicals
- Developer for paper
- Stop bath for paper
- Fixer for paper
- Graduated cylinder
- Thermometer
- Timer
- Tongs for handling paper

Steps:
1. Load the negative onto the enlarger and project it onto the photographic paper.
2. Adjust the size and focus of the image.
3. Mix the developer and water according to the dilution instructions on the bottle and the amount of chemistry needed for your paper.
4. Fill the developer tray with the developer solution and the stop bath tray with stop bath solution.
5. Expose the paper to light according to the instructions on the paper box.
6. Develop the paper by placing it in the developer tray and agitating for the required amount of time.
7. Rinse the paper in the stop bath tray and then rinse it thoroughly in water.
8. Fix the paper by placing it in the fixer tray and agitating for the required amount of time.
9. Rinse the paper thoroughly in water.
10. Hang the paper to dry.

Keep in mind that developing film and making prints require a darkroom or a light-tight space with the necessary equipment and materials. It's important to follow safety instructions and use proper ventilation when handling chemicals.
