+Every time that I do a clean install on my machine it takes a few hours
+till I get to point where I was before formatting it, install all
+packages, select themes, icons, fonts, install IDEs, extensions and so
+on. After doing it a few times I came to the conclusion that I would
+save time by spending time automating this chore, and as a result, I
+could tinker a little more with my system and not worry about spending a
+weekend re-installing everything (which have happened more time that
+        I\'d like to remember).
+
+So after a few attempts using python and bash I ended with many files
+and keep everything organized and concise turned out to be more tedious
+than the setup itself. So there comes
+[Ansible](https://www.ansible.com/). It is an enterprise-graded software
+used to automate tasks. It has A LOT OF features and it can be really
+helpful if you\'re a sysadmin but for now we\'re going to focus on
+[Ansible
+Pull](https://docs.ansible.com/ansible/latest/user_guide/playbooks_intro.html#ansible-pull)
+and
+[Playbooks](https://docs.ansible.com/ansible/latest/user_guide/playbooks.html).
+As better described:
+
+> \[Ansible-Pull\] is used to up a remote copy of ansible on each
+> managed node, each set to run via cron and update playbook source via
+> a source repository. This inverts the default push architecture of
+> Ansible into a pull architecture, which has near-limitless scaling
+> potential.
+>
+> Playbooks are Ansible's configuration, deployment, and orchestration
+> language. They can describe a policy you want your remote systems to
+> enforce, or a set of steps in a general IT process.
+>
+> [source](https://docs.ansible.com/ansible/latest/cli/ansible-pull.html)
+
+The goal is to pull and run a playbook remotely using a git repository.
+The playbook will describe the tasks needed to setup our machine from
+scratch.
+
+But first lets tinker a bit a with playbooks locally with
+`ansible-playbook`, to do so we need to add `localhost` to ansible\'s
+hosts list. Add it to `/etc/ansible/hosts`:
+
+``` service
+[all]
+localhost
+```
+
+As an experiment we\'re going to write a asks to install vim. Currently,
+   I\'m using [Fedora](https://getfedora.org/) thus we going to use [dnf
+   modeule](https://docs.ansible.com/ansible/latest/modules/dnf_module.html)
+   to install packages, but if you\'re using another distribution look for
+   a equivalent module like [apt
+   module](https://docs.ansible.com/ansible/latest/modules/apt_module.html)
+   for [Ubuntu](https://ubuntu.com/).
+
+   The playbook to install is quite simple:
+
+   ``` yaml
+# main.yaml
+   - hosts: all
+   tasks:
+   - name: install vim
+   dnf:
+name: vim
+state: latest
+```
+
+`hosts:` is required and it has to match our hosts otherwise the
+playbook won\'t run.
+
+`tasks:` is the list of tasks that the playbook will perform, in this
+case will be `dnf install vim`.
+
+To run a playbook use the command `ansible-playbook` commando to run
+`main.yml` direct from disk, do to so just run the following command:
+
+
+``` bash
+sudo ansible-playbook --connection=local main.yml
+```
+
+After a few seconds, vim will be installed on your machine.
+
+``` bash
+PLAY [all] *************************************************************
+
+TASK [Gathering Facts] *************************************************
+ok: [localhost]
+
+TASK [install vim] *****************************************************
+ok: [localhost]
+
+PLAY RECAP *************************************************************
+localhost                  : ok=2    changed=0    unreachable=0    failed=0
+```
+
+This is the first step, next part we shall create a more complex
+playbook and setup repository to run it remotely using `ansible-pull`.
