** On Unix-like platforms such as Linux/macOS, there's a [https://raw.githubusercontent.com/devkitPro/installer/master/perl/devkitARMupdate.pl Perl script]. Make sure you also select libctru and the 3ds examples when installing.
* Depending on the kind of homebrew you want to develop, you may be interested in installing and using additional libraries and tools which don't ship alongside devkitARM/libctru. A list of them can be found in [[Homebrew Libraries and Tools]].

devkitPro provides Win32-native precompiled versions of devkitARM which can be run directly on Windows.
* If you already use msys2 then you can follow the instructions at https://github.com/devkitPro/pacman/releases/latest to add the devkitPro repositories.
* [https://github.com/devkitPro/installer/releases/latest download the latest version of the graphical installer] from SourceForge and run it, following the instructions as you go.
 
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.

* You will want to make sure devkitARM is selected during the installation process to develop for the 3DS (and also the DS and GBA) - you can also install devkitPPC (for GameCube/Wii development) and devkitPSP (for PlayStation Portable development) if you wish.
* Ensure at least "3DS Development" is ticked - you can also leave the other options ticked if you wish.

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.

* First, you need to install curl so the installer can download the devkitARM packages, and you should also install Git - you'll need it to update libctru or share your code on GitHub, among many other things. If you are running Linux, you'll also need wget; it comes preinstalled on most distributions, but not all.
* 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
* Find your way into a shell (eg. by opening a Terminal window), and follow the instructions for your OS:
* logout and login again to get the environment settings needed.
** Debian/Ubuntu/Linux Mint/Ubuntu on WSL: <code>sudo apt-get install git curl</code>
** Fedora/CentOS/RHEL: <code>sudo yum install git curl</code>
** openSUSE: <code>sudo zypper install git curl</code>
** Arch Linux/ALWSL: <code>sudo pacman -S git curl wget</code>
** macOS: Download Git from [http://git-scm.com/download/mac] and install it. Curl is included with the OS.
 
* Next, we need to download, make executable and run the devkitARM updater (don't worry, the updater is also the installer.)
<pre>
curl -L https://raw.githubusercontent.com/devkitPro/installer/master/perl/devkitARMupdate.pl -o devkitARMupdate.pl
chmod +x ./devkitARMupdate.pl
./devkitARMupdate.pl
</pre>
 
You can either use sudo here or chown /opt/devkitpro to be writable by your user before running the script.

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].
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
There are now too many to list here in detail, so go ahead and browse them.
 
* To download these, if you installed Git (as you will have if you followed the above instructions), simply type <code>git clone https://github.com/devkitPro/3ds-examples.git</code> into your shell in the directory you wish to store the 3ds-examples folder in.


These can be built from the command line.
