If you've [configured your DNS](configuring-dns.md) and have [configured the playbook](configuring-playbook.md), you can start the installation procedure.
The Ansible playbook's tasks are tagged, so that certain parts of the Ansible playbook can be run without running all other tasks.
The general command syntax is: `ansible-playbook -i inventory/hosts setup.yml --tags=COMMA_SEPARATED_TAGS_GO_HERE`
Here are some playbook tags that you should be familiar with:
-`setup-all` - runs all setup tasks for all components, but does not start/restart services
-`setup-SERVICE` (e.g. `setup-bot-postmoogle`) - runs the setup tasks only for a given role, but does not start/restart services. You can discover these additional tags in each role (`roles/*/main.yml`). Running per-component setup tasks is **not recommended**, as components sometimes depend on each other and running just the setup tasks for a given component may not be enough. For example, setting up the [mautrix-telegram bridge](configuring-playbook-bridge-mautrix-telegram.md), in addition to the `setup-mautrix-telegram` tag, requires database changes (the `setup-postgres` tag) as well as reverse-proxy changes (the `setup-nginx-proxy` tag).
-`start` - starts all systemd services and makes them start automatically in the future
-`stop` - stops all systemd services
-`ensure-matrix-users-created` - a special tag which ensures that all special users needed by the playbook (for bots, etc.) are created
`setup-*` tags **do not start services** automatically, because you may wish to do things before starting services, such as importing a database dump, restoring data from another server, etc.
## 1. Installing Matrix
If you **don't** use SSH keys for authentication, but rather a regular password, you may need to add `--ask-pass` to the all Ansible commands
If you **do** use SSH keys for authentication, **and** use a non-root user to *become* root (sudo), you may need to add `-K` (`--ask-become-pass`) to all Ansible commands
There 2 ways to start the installation process - depending on whether you're [Installing a brand new server (without importing data)](#installing-a-brand-new-server-without-importing-data) or [Installing a server into which you'll import old data](#installing-a-server-into-which-youll-import-old-data).
### Installing a brand new server (without importing data)
If this is **a brand new** Matrix server and you **won't be importing old data into it**, run all these tags:
This will do a full installation and start all Matrix services.
Proceed to [Maintaining your setup in the future](#2-maintaining-your-setup-in-the-future) and [Finalize the installation](#3-finalize-the-installation)

## 2. Maintaining your setup in the future
Feel free to **re-run the setup command any time** you think something is off with the server configuration. Ansible will take your configuration and update your server to match.
Now that services are running, you need to **finalize the installation process** (required for federation to work!) by [Configuring Service Discovery via .well-known](configuring-well-known.md).
After you have started the services and **finalized the installation process** (required for federation to work!) by [Configuring Service Discovery via .well-known](configuring-well-known.md), you can:
- [check if services work](maintenance-checking-services.md)
- or [create your first Matrix user account](registering-users.md)
- or [set up additional services](configuring-playbook.md#other-configuration-options) (bridges to other chat networks, bots, etc.)
- or learn how to [upgrade services when new versions are released](maintenance-upgrading-services.md)
- or learn how to [maintain your server](faq.md#maintenance)
- or join some Matrix rooms:
* via the *Explore rooms* feature in Element or some other client, or by discovering them using this [matrix-static list](https://view.matrix.org). Note: joining large rooms may overload small servers.
* or come say Hi in our support room - [#matrix-docker-ansible-deploy:devture.com](https://matrix.to/#/#matrix-docker-ansible-deploy:devture.com). You might learn something or get to help someone else new to Matrix hosting.
