Install [https://devkitpro.org/ devkitARM]. If it's already installed, update it using sudo (dkp-)pacman -Syu. On Windows, there's a [https://github.com/devkitPro/installer/releases/latest graphical installer]. On Unix-like platforms such as Linux/macOS, there's [https://github.com/devkitPro/pacman/releases/latest pacman]..
==Linux==
==Windows==
* First get the devkitARM updater Perl script for Linux.
* If you already use msys2 then you can follow the instructions at https://github.com/devkitPro/pacman/releases/latest to add the devkitPro repositories.
Otherwise
* [https://github.com/devkitPro/installer/releases/latest download the latest version of the graphical installer] from github and run it, following the instructions as you go.
./devkitARMupdate.pl /opt/devkitpro
* An Internet connection is required.
* Ensure at least "3DS Development" is ticked - you can also leave the other options ticked if you wish.
* Once the installer has finished, launch MSYS from:
** Windows 7 and earlier: Start -> All Programs -> devkitPro -> MSYS
** Windows 8 and 8.1: Right click on the Start screen and select 'All Apps'. You should find MSYS there.
** Windows 10 (pre-Anniversary Update): Start -> All Apps -> devkitPro -> MSYS
** Windows 10 (post-Anniversary Update): Start -> devkitPro -> MSYS
Alternatively starting with Windows 10 Anniversary Update (Version 1607), the [https://msdn.microsoft.com/en-us/commandline/wsl/install_guide Windows Subsystem for Linux (WSL)] may also be used to run the Linux version of devkitARM. Unless you have some particular need for WSL it's recommended that you stick to a more standard environment.
==Unix-like platforms==
Currently devkitPro provides precompiled versions of devkitARM for the following Unix-like platforms: Linux (x86_64), macOS (x86_64). Note that Linux x86_64 binaries are usable under WSL.
* Follow the instructions to install pacman found at https://github.com/devkitPro/pacman/releases/latest
* run sudo (dkp-)pacman -S 3ds-dev to install the tools and libraries for 3ds development
* logout and login again to get the environment settings needed.

= Building the examples =
3DS examples are still being created. Currently there are a few examples in the separate ctrulib download under the "examples" folder.
3DS examples are still being created; however, there are a growing number of examples available from the [https://github.com/devkitPro/3ds-examples devkitPro/3ds-examples GitHub repository]. These are downloaded by the installer and can be found in $DEVKITPRO/examples/3ds
These can be built from the command line.
To start a new homebrew project from the <code>bash</code> shell, simply type the following (replacing <code>'''~/projects/my3dsproject'''</code> with the place you would like your project to be stored, with <code>~</code> meaning your HOME directory):
cp -r $DEVKITPRO/examples/3ds/templates/application '''~/projects/my3dsproject'''
cd '''~/projects/my3dsproject'''
The standard Makefile will use the folder as the name of the 3dsx that will be built. You can keep that behaviour or simply change the <code>TARGET := $(notdir $(CURDIR))</code> line in the Makefile to explicitly name your project.
To compile it, type <code>make</code> in the project directory.
==Building the examples on Linux with Netbeans==
==Running your code==
To run it on your 3DS, start the Homebrew Launcher, press Y to open the network loader, then on your PC type: <code>$DEVKITPRO/tools/bin/3dslink '''my3dsproject'''.3dsx</code>, replacing '''my3dsproject''' with the name of the 3dsx file you want to run.)
<pre>export DEVKITPRO=/opt/devkitpro
<pre>/opt/devkitpro/devkitARM/include;/opt/devkitpro/ctrulib/libctru/include</pre>
If all goes well, you'll soon see your application running on your 3DS. If not, it could help to add <code>-a '''ipaddress'''</code>, replacing '''ipaddress''' with the ip address of the console (visible on homebrew launcher after pressing Y).

= Troubleshooting =
'''I get the "Please set DEVKITARM in your environment." error.'''
Ensure you have the devkit-env package installed - (dkp-)pacman -Sl | grep devkit-env. Logout and login to get the enviroment settings.
For WSL users, you need to close the Bash shell, then reopen it for WSL to reload all of the variables from a clean state.
