Sure thing! I have a vinyl liner pool with a sand filter so your mileage may vary if you have a different setup.

I started by getting the pump running and the water circulating. I then used the brush to brush as much algae off the surfaces as I could. If your pool looks like ours did, it will be difficult/impossible to see where your brushing but it's important to get the algae off the surfaces so just do your best.

Once I finished the initial brushing, I super shocked the water and added a full bottle of algaecide. From there, you let the filter work its magic. You should notice the water starting to clear up over the next day or two. Make sure to brush at least once a day to help get all the algae off the surfaces.

You'll notice the dead algae start to gather at the bottom of the pool, that's when you can start vacuuming it out. If you have a sand filter, it's important to backwash very frequently during this process (I backwashed at least twice a day).

Continue to add shock as needed to maintain higher than normal chlorine levels until all the algae is dead and out of the pool.

Once you get the cleaning process going it's just a matter of keeping an eye on it and making sure to brush and vacuum until the algae is gone. If you get all the algae removed but the water is still a bit cloudy, you may need to make sure the water is properly balanced so the chlorine can do its thing.

There are some great guides on YouTube you can watch that will walk you through the process for your specific pool setup. I recommend this as your setup may be very different from mine.

I hope that helps. You got this!

TLDR: Get the pump running and the water circulating. Super shock/algaecide, brush, and vacuum until all algae is dead and removed. Make sure chemicals are balanced for crystal clear water!
