 # Configuring the Ansible playbook
 
-Once you have your server and you have [configured your DNS records](configuring-dns.md), you can proceed with configuring this playbook, so that it knows what to install and where.
+To configure the playbook, you need to have done the following things:
 
-You can follow these steps:
+- have a server where Matrix services will run
+- [configured your DNS records](configuring-dns.md)
+- [retrieved the playbook's source code](getting-the-playbook.md) to your computer
+
+You can then follow these steps inside the playbook directory:
 
 - create a directory to hold your configuration (`mkdir inventory/host_vars/matrix.<your-domain>`)

+# Getting the playbook
+
+This Ansible playbook is meant to be executed on your own computer (not the Matrix server).
+
+In special cases (if your computer cannot run Ansible, etc.) you may put the playbook on the server as well.
+
+You can retrieve the playbook's source code by:
+
+- [Using git to get the playbook](#using-git-to-get-the-playbook) (recommended)
+
+- [Downloading the playbook as a ZIP archive](#downloading-the-playbook-as-a-zip-archive) (not recommended)
+
+
+## Using git to get the playbook
+
+We recommend using the [git](https://git-scm.com/) tool to get the playbook's source code, because it lets you easily keep up to date in the future when [Maintaining services](maintenance-upgrading-services.md).
+
+Once you've installed git on your computer, you can go to any directory of your choosing and run the following command to retrieve the playbook's source code:
+
+```bash
+git clone https://github.com/spantaleev/matrix-docker-ansible-deploy.git
+```
+
+This will create a new `matrix-docker-ansible-deploy` directory.
+You're supposed to execute all other installation commands inside that directory.
+
+
+## Downloading the playbook as a ZIP archive
+
+Alternatively, you can download the playbook as a ZIP archive.
+This is not recommended, as it's not easy to keep up to date with future updates. We suggest you [use git](#using-git-to-get-the-playbook) instead.
+
+The latest version is always at the following URL: https://github.com/spantaleev/matrix-docker-ansible-deploy/archive/master.zip
+
+You can extract this archive anywhere. You'll get a directory called `matrix-docker-ansible-deploy-master`.
+You're supposed to execute all other installation commands inside that directory.
+
+
+---------------------------------------------
+
+No matter which method you've used to download the playbook, you can proceed by [Configuring the playbook](configuring-playbook.md).
