| Most frequently asked questions. |
| -------------------------------- |
| |
| 1. **How much does Docker cost?** |
| |
| Docker is 100% free, it is open source, so you can use it without paying. |
| |
| 2. **What open source license are you using?** |
| |
| We are using the Apache License Version 2.0, see it here: https://github.com/dotcloud/docker/blob/master/LICENSE |
| |
| 3. **Does Docker run on Mac OS X or Windows?** |
| |
| Not at this time, Docker currently only runs on Linux, but you can use VirtualBox to run Docker in a virtual machine on your box, and get the best of both worlds. Check out the MacOSX_ and Windows_ installation guides. |
| |
| 4. **How do containers compare to virtual machines?** |
| |
| They are complementary. VMs are best used to allocate chunks of hardware resources. Containers operate at the process level, which makes them very lightweight and perfect as a unit of software delivery. |
| |
| 5. **Can I help by adding some questions and answers?** |
| |
| Definitely! You can fork `the repo`_ and edit the documentation sources. |
| |
