I have added a new course under the Django section. It was undoubtedly a must. It teaches everything from head to toe! From creating a simple **Hello World** site to a fully functional website to deployment! All is here!

I have added a new, head-to-toe, yet free course under the Flask section. I personally have taken this course on YouTube and I have to say it was phenomenal. It's also one of the very few updated tutorials regarding Flask out there, as of recently updated in Feb 2022. It also has a lot of detail, which is worth knowing!
