Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.

• Sensible defaults with minimal configuration required.
• Clean, clear, concise code.
• Unified desktop environment.

Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.

See ReadMe.Compiling.

Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!

If you're submitting a patch to us, please make sure you're following the patch submitting guidelines.

If you're having trouble finding something in the source tree, you can use one of our web-based source code browsers:

• https://xref.landonf.org/ (OpenGrok, provided by Landon Fuller)
• https://git.haiku-os.org/ (git, provided by Haiku, Inc.)

The main piece of documentation that still needs work are the API docs (found in the tree at docs/user). Just find an undocumented class, write documentation for it, and submit a patch.
