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.

# 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/).

### Capabilities

  * 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

# 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).
