You are interested in getting familiar with the GNU/Hurd system architecture,
or specific components of it? Here is a collection of texts to read.
/!\ A lot of stuff is still missing ([[!taglink open_issue_documentation]]).

# Basic Knowledge
Before you can go details, you have to learn the basics about operating system
architecture. Yes, really.
## Operating Systems Basics
You can find good free, self-paced online courses about operating systems on <https://www.udacity.com/> .
A free textbook about operating systems is called [Operating Systems: Three Easy Pieces](http://pages.cs.wisc.edu/~remzi/OSTEP/).
## GNU/Hurd System Architecture
### Capabilities
[[!toggleable id=shapiro_capintro_1999 text="""[[!template id=note
text="*[[shapiro\_capintro\_1999|capability]]*:
{{$capability#shapiro_capintro_1999}}.
{{$capability#shapiro_capintro_1999_text}}."]]"""]]
* Our use of [[capabilities|capability]]. The
{{$capability#wikipedia_capability-based_security}} article.
Alternatively/additionally, [[!toggle id=shapiro_capintro_1999
text="[shapiro\_capintro\_1999]"]].
In the GNU/Hurd system, a [[capability]] is represented by a [[Mach
port|microkernel/mach/port]].
* {{$capability#wikipedia_object-capability_model}}. Albeit not directly
tailored at the GNU/Hurd operating system architecture, this article anyway
does a good job at describing general principles of a [[capability]]-based
system architecture.
# Quick overview
You may want to start reading a [[quick overview|overview]] of how the GNU/Hurd system
starts, and thus how it is structured.
# FAQ
[[FAQ]]
# Specific Components
The GNU/Hurd system is composed of the Hurd servers running on top of the
GNU Mach microkernel. Mach only handles scheduling tasks and threads, memory
management, and message passing. Mig is used to abstract RPCs on top of Mach's
message passing. Eventually, the Hurd servers and Unix processes discuss with
each other using these RPCs.
Depending on your background, you may want to start reading the documentation
from userlandish interfaces (Hurd) or from the micro kernel itself (Mach).
