== Basics ==
* [http://www.geda-project.org/ gEDA Project Homepage] 
* [https://answers.launchpad.net/geda gEDA Answers @ Launchpad]: Have questions about how to do something with gEDA?  You can ask the developers.
* [http://www.opencircuits.com/GEDA All about gEDA] at Open Circuits



== Installing gEDA ==

=== Installing gEDA on Windows ===
* gEDA can be run on Windows natively, as a cygwin application, or in a virtual machine.
* "Official" Windows installers are available [http://www.delorie.com/pcb/geda-windows/ here], maintained by [http://www.delorie.com/ DJ Delorie], one of the core gEDA developers.
* In case of difficulty with the latest, "official" versions, consider [http://bibo.iqo.uni-hannover.de/dokuwiki/doku.php?id=english:geda_for_ms-windows this set] of unofficial installers.  
* Virtual machine method: Download [http://www.virtualbox.org/ Virtualbox] and download [http://www.ubuntu.com Ubuntu], so that you can run Ubuntu in a virtual machine on your computer. (It's fast and easy!) Then, install gEDA (gschem and PCB) from the Ubuntu software center. 


=== Installing gEDA on Mac ===
* gEDA can be run on the Mac as an X11 application or in a virtual machine.
* Standard method 1: Use [http://www.finkproject.org/ MacPorts], and install both "geda-gaf" and "pcb."   You may also want to use the [http://porticus.alittledrop.com/ Porticus] GUI to make that process easier.
* Standard method 2: Use [http://www.finkproject.org/ Fink], and install the "geda-bundle."    You may also want to use the [http://finkcommander.sourceforge.net/ Fink Commander] GUI to make that process easier. More about this process [http://www.ghz.cc/charles/fink/ here].  
* Standard method 3: Use [http://mxcl.github.com/homebrew/ Homebrew] and "brew install geda-gaf pcb".
* Virtual machine method: Download [http://www.virtualbox.org/ Virtualbox] and download [http://www.ubuntu.com Ubuntu], so that you can run Ubuntu in a virtual machine on your computer. (It's fast and easy!) Then, install gEDA (gschem and PCB) from the Ubuntu software center.  Note: this is ''faster'' than the Fink method-- under 1 hour, if you have a reasonably fast internet connection.
* Option 4: We highly recommend the pcb-rnd fork of PCB, available at [http://repo.hu/projects/pcb-rnd/ http://repo.hu/projects/pcb-rnd/], which is an actively developed fork implementing additional features and emphasizing portability. On the Mac, this is certainly the best option for the pcb part of gEDA.

Once you have gEDA installed on Mac you can launch the applications by running their specific apps (gschem, pcb, gerbv, xgsch2pcb) in the terminal. [http://www.msarnoff.org/geda-mac/ Matt Sarnoff wrote wrapper applications] which you can install into your applications directory to launch the appropriate file using the associated application just by double clicking on it. Depending on which option you used to install gEDA you may need to remap them in your PATH. Instruction are in his readme.


=== Installing gEDA on Linux ===
* In Ubuntu, install gEDA (gschem and PCB) from the Ubuntu software center. 
* Similar packages are available for other Linux flavors, for example as [http://packages.debian.org/sid/geda Debian Packages].
* Those familiar with git, those keen to contribute to the code base, and those seeking the latest version, should consider building from source under linux, see [http://git.geda-project.org/ git.geda-project.org] for further details.
* Alternatively, you can try the pcb-rnd fork of PCB, available at [http://repo.hu/projects/pcb-rnd/ http://repo.hu/projects/pcb-rnd/], which is an actively developed fork implementing additional features and emphasizing portability. It should build on most Unix platforms with a C89 compiler and either GTK or motif for the GUI. Debian .deb packages are now available. Support for gl acceleration is now available in the default svn configuration.

It builds on MacOS X and most unix systems with a C89 compiler and either GTK, with or without gl, or motif for the GUI. It now supports export of footprints and PCB layouts to kicad legacy (.brd) and (.mod) format, as well as an advanced search dialog for finding features on a design, and supports scripting. pcb-rnd now supports import and export of kicad s-expression layouts, including modules, in addition to direct export of the kicad legacy formats. Specctra DSN export for use with freerouter is supported, as well as Specctra DSN import. pcb-rnd also supports importing KiCad Eeschema schematic netlists, as well as TinyCad, Mentor Design Capture netlists and LT-Spice netlists, as well as MUCS autorouter layouts. pcb-rnd also supports import and export of Protel Autotrax/Easytrax layouts, as well as Eagle XML and Eagle binary (v3, v4, v5) PCB layouts (including embedded netlists) and Eagle binary & XML footprint library (.lbr) import. pcb-rnd also has support for HPGL import.
