The GPL is a copyleft license, which means that any software released under this license must also be distributed under the same terms. This ensures that the software remains free and open-source, even if it is modified or incorporated into other projects.
Under the GPL, users have the freedom to run, study, modify, and distribute the software. This includes the freedom to make changes to the source code, as well as the freedom to distribute modified versions of the software.

- No Discrimination: The GPL prohibits any restrictions on who can use the software or the purposes for which it can be used.
- Compatibility: The GPL is compatible with many other open-source licenses, allowing for collaboration and sharing of code.
