Fenced code blocks inside ordered and unordered lists

1. This is a numbered list.

2. I'm going to include a fenced code block as part of this bullet:

This gist describes how to use the ImageMagick and OpenSSL command line tools to encrypt an image using ECB mode.

First we need to gather some information about the original image. This will tell us what size to use in our final step.

$ identify Braintree.png
Braintree.png PNG 898x229 898x229+0+0 8-bit sRGB 65KB 0.000u 0:00.000

Looks like the image is 898x229.

Next we need to convert the image into the RGBA format. This is a simple binary format that only contains uncompressed pixel data and no meta information, like image dimensions.

Mainline kernel

After your fresh CentOS 7 setup (make sure you install the QEMU/KVM virtualization tools and virt-manager), install the mainline kernel:

sudo rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
sudo rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm
sudo yum --enablerepo=elrepo-kernel install kernel-ml
sudo yum -y update
