-  In this tutorial I'll get you through setting up a Raspberry Pi with Perl 6.
-  I am using a Raspberry Pi 3 myself, but other versions should work fine too.

-= Perl 6 - Setting up a Raspberry Perl
-:toc: preamble
-
-In this tutorial I'll get you through setting up a Raspberry Pi with
-https://perl6.org/[Perl 6]. I am using a Raspberry Pi 3 myself, but other
-versions should work fine too. However, older versions are slower, so it might
-take a bit longer to install completely.
-
-[NOTE]
-====
-For those who have never had a Raspberry Pi before, you will need
-the following:
-
-- Raspberry Pi board
-- Power supply (5v 2A, micro USB)
-- SD card of at least 4gb, but I would advise at least 8gb
-- Monitor with HDMI cable
-- Keyboard
-====
-
-Perl 6 will be installed using
-https://github.com/tadzik/rakudobrew[Rakudobrew], which I'll also be using to
-get https://github.com/ugexe/zef[zef] installed. Zef is the recommended module
-manager for Perl 6.
-
-== Setting up Raspbian
-
-The first step is getting the OS set up. To keep this tutorial simple, I will
-stick to https://www.raspbian.org/[Raspbian], but if you feel confident in your
-skills you can use any other distribution or OS. Perl 6 installs the same on
-all UNIX(-like) operating systems.
-
-=== Get the image
-
-First, https://www.Raspberrypi.org/downloads/raspbian/[download the Raspbian
-image from the Raspberry Pi download page]. I chose the `LITE` version, but if
-you prefer having a graphical desktop you can go for the `DESKTOP` version
-instead.
-
-At the time of writing, this means I got the
-`2017-09-07-raspbian-stretch-lite.zip`. If you want to verify you got the
-correct download and nothing went wrong saving it to your disk, you can verify
-the checksum. The checksum for your download is noted below the download links.
-To get the checksum of the file you downloaded, use `sha256sum` as follows:
-
-NOTE: Lines prepended with a `$` are to be ran as your normal user, whereas
-lines with a `#` are ment to be ran as "super user". This can be done by using
-a privilege escalation program, such as
-https://www.linux.com/blog/how-use-sudo-and-su-commands-linux-introduction[`sudo`].
-
-[source]
-----
-$ sha256sum 2017-09-07-raspbian-stretch-lite.zip
-----
-
-If the checksum matches the one noted below the download button you used, it
-should be fine, and you can continue with extracting the image from the zip
-using `unzip`:
-
-[source]
-----
-$ unzip 2017-09-07-raspbian-stretch-lite.zip
-----
-
-This will result in a similarly named file, but with a `.img` extension instead
-of `.zip`. This is the image that you can write to the SD card.
-
-=== Write the image to the SD card
-
-This step is pretty easy, but typos here can be disastrous for the system
-you're using to write to the SD card.
-
-Open a terminal and run `dmesg -w` as super user (usually doable using `sudo
-dmesg -w`). This will give immediate feedback when you insert your SD card, and
-shows which device it is being assigned to. In my case, this was `sdb`, which
-means the device file resides at `/dev/sdb`.
-
-Now, to actually write the image, I'll use `dd` since this is everyone's
-favourite tool, it seems. If you feel adventurous enough to try out something
-different, feel free to read up on
-https://www.vidarholen.net/contents/blog/?p=479[Useless Use of dd].
-
-Make sure to make the `if` argument point to the correct path with your
-extracted raspbian image, and `of` to point to the correct device as identified
-earlier. In order to be allowed to run this command, you must be root, which
-can be achieved by using `sudo` or `doas` again.
-
-[source]
-----
-# dd bs=4M status=progress if=/path/to/2017-09-07-raspbian-stretch-lite.img of=/dev/sdb
-$ sync
-----
-
-Afterwards, plug it into your Raspberry Pi and attach all cables you might
-need. Think of stuff like a keyboard, mouse, monitor, internet, power. Do power
-last, as the Raspberry Pi will start immediatly once it receives power.
-
-=== First boot
-
-The Raspberry Pi should start booting the moment you supply it with power. If
-you attach the HDMI after the power, it's possible you won't have display
-working, so make sure HDMI is attached before powering up.
-
-You'll see some text scrolling by, up to a point where it asks you for a
-`login`, and accepts keyboard input. The default username is `pi`, and the
-default password is `Raspberry`. You are strongly advised to change the
-password upon login, which can be done in the next step.
-
-=== Configuration
-
-The Raspberry Pi comes with its own configuration tool, `raspi-config`. Run
-this with `sudo` prepended in front of it so you gain the right privileges. I
-would advise you to at least change the user password from here. After this you
-should go to `Advanced Options` and expand the filesystem. This will grow the
-filesystem to the entire SD card's size.
-
-TIP: To get to the buttons on the bottom (`Select`, `Finish` and `Back`), use
-the arrow keys to go left or right.
-
-You can look around the tool for other interesting things to modify. Once you
-are satisfied, go back to the main menu and choose `Finish`. It will ask to
-reboot, which you should accept. This will apply all the new configurations you
-just made.
-
-=== Updating and installing additional packages
-
-It's rare for the system to be completely up to date after installing the image
-on the SD card. Additionally, you also need some extra packages in order to get
-rakudobrew, and to install Perl 6 itself. For this, we use the package manager
-bundled with raspbian, `apt`:
-
-[source]
-----
-# apt update
-# apt upgrade
-----
-
-This will update the package lists, and then upgrade all outdated packages to
-their newest versions. You should do this at least once a week to make sure
-your system stays up to date.
-
-Once the upgrades are finished, you can install some new packages which are
-needed later on in this tutorial:
-
-[source]
-----
-# apt install git build-essential
-----
-
-`git` is required to get the rakudobrew repository and is also used by
-rakudobrew itself to get the sources needed to build Perl 6 and to install zef.
-The `build-essential` package comes with all sorts of tools to build software,
-which is required to build Perl 6.
-
-== Installing Perl 6
-
-Now, we've got a working Raspberry Pi installation. We can start doing things
-with it, such as playing around with Perl 6.
-
-=== Setting up Rakudobrew
-
-Rakudobrew is a nice tool to manage Perl 6 installations on your system. It can
-also install `zef` for you, so you don't have to deal with this manually. This
-is all documented on the repository's `README.md` file as well, but I'll
-explain it here too. I do make a few small tweaks here and there to match my
-preferred setup more closely.
-
-Clone the repository to your system, and add it to your `$PATH` to be able to
-use the scripts bundled with it:
-
-[source]
-----
-$ mkdir -p ~/.local/var
-$ git clone https://github.com/tadzik/rakudobrew.git ~/.local/var/rakudobrew
-$ export PATH=${HOME}/.local/var/rakudobrew/bin:$PATH
-$ hash -r
-----
-
-The `hash -r` call will rehash your PATH, so you can tab-complete `rakudobrew`.
-Next, initialize rakudobrew:
-
-[source]
-----
-$ rakudobrew init
-----
-
-This will give you a notification to automatically load rakudobrew next time.
-It is advised you follow that message, so you won't have to do it manually each
-time you log in to the system.
-
-=== Installing Perl 6 with MoarVM backend
-
-Now that rakudobrew is installed and available to use, it's time to make use of
-it to install Perl 6.
-
-[source]
-----
-$ rakudobrew build moar
-----
-
-=== Installing zef, the module manager
-
-Getting zef to work isn't much harder than installing Perl 6, but its a lot
-faster. You can have rakudobrew take care of this too:
-
-[source]
-----
-$ rakudobrew build zef
-----
-
-== Final words
-
-And that should be it, you now have a working Perl 6 installation with the zef
-module manager to take care of installing and upgrading modules. Now you just
-need to come up with a nice project to work on to start using and learning the
-wonders of Perl 6.
-
-If you need any help on getting started, try the `#perl6` IRC channel on
-Freenode, or check out some of the Perl 6 documentation and introduction sites:
-
-- https://docs.perl6.org/
-- http://perl6intro.com/
-
-For starting projects that are easy to start with and can bring quick results,
-consider making an IRC bot using
-https://github.com/zoffixznet/perl6-IRC-Client[`IRC::Client`], or a small web
-application using https://github.com/Bailador/Bailador[`Bailador`].
