 To create an Ansible DEB package:
 
-    sudo apt-get install python-paramiko python-yaml python-jinja2 python-httplib2 python-setuptools python-six sshpass
-    sudo apt-get install cdbs debhelper git-core reprepro fakeroot asciidoc devscripts docbook-xml xsltproc libxml2-utils
-    sudo apt-get install dh-python build-essential
-    git clone git://github.com/ansible/ansible.git
-    cd ansible
-    make deb
+__Note__: You must run this target as root or set `PBUILDER_BIN='sudo pbuilder'`
 
-On older releases that do not have `dh-python` (like Ubuntu 12.04), install `python-support` instead:
+```
+apt-get install asciidoc cdbs debootstrap devscripts make pbuilder python-setuptools
+git clone git://github.com/ansible/ansible.git
+cd ansible
+git submodule update --init
+DEB_DIST='xenial trusty precise' make deb
+```
 
-    sudo apt-get install python-support
+Building in Docker:
 
-The debian package file will be placed in the `../` directory. This can then be added to an APT repository or installed with `dpkg -i <package-file>`.
+```
+git clone git://github.com/ansible/ansible.git
+cd ansible
+git submodule update --init
+docker build -t ansible-deb-builder -f packaging/debian/Dockerfile .
+docker run --privileged -e DEB_DIST='trusty' -v $(pwd):/ansible ansible-deb-builder
+```
+
+The debian package file will be placed in the `deb-build` directory. This can then be added to an APT repository or installed with `dpkg -i <package-file>`.
 
 Note that `dpkg -i` does not resolve dependencies.
 
 To install the Ansible DEB package and resolve dependencies:
 
-    sudo dpkg -i <package-file>
-    sudo apt-get -fy install
+```
+dpkg -i <package-file>
+apt-get -fy install
+```
 
 Or, if you are running Debian Stretch (or later) or Ubuntu Xenial (or later):
 
-    sudo apt install <package-file>
+```
+apt install /path/to/<package-file>
+```
