### Advantages of Free Software <a href="#advantages-of-free-software" id="advantages-of-free-software"></a>

> A program is free software if the program's users have the four essential freedoms: [\[1\]](https://www.gnu.org/philosophy/free-sw.html#f1)
>
> \* The freedom to run the program as you wish, for any purpose (freedom 0).
>
> \* The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this.
>
> \* The freedom to redistribute copies so you can help others (freedom 2).
>
> \* The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can **give the whole community a chance to benefit from your changes**. Access to the source code is a precondition for this.
