It will take a long time to install so can continue with your other work while downloading. It includes all packages that are required no need for any other.
Yesterday, there was a presentation on latex which includes basics that are required to start using latex. It can be used to make presentation, reports, articles, etc. Very useful software which includes a great algorithm behind it.
There are two more presentation this week which includes templates, using mathematical equations, graphs, and many other features of latex.
No need to go for a MS-Powerpoint or MS-Word when everything is available in LaTeX which is a open-source also. 🙂
