# Configuring Hydrogen (optional)
|
||||
|
||||
This playbook can install the [Hydrogen](https://github.com/vector-im/hydrogen-web) Matrix web client for you.
|
||||
Hydrogen is a lightweight web client that supports mobile and legacy web browsers.
|
||||
Hydrogen can be installed alongside or instead of Element.
|
||||
|
||||
If you'd like Hydrogen to be installed, add the following to your configuration file (`inventory/host_vars/matrix.<your-domain>/vars.yml`):
|
||||
|
||||
```yaml
|
||||
matrix_client_hydrogen_enabled: true
|
||||
```
|
||||
|
||||
You will also need to add a DNS record so that Hydrogen can be accessed.
|
||||
By default Hydrogen will use https://hydrogen.DOMAIN so you will need to create an CNAME record
|
||||
for `hydrogen`. See [docs/configuring-dns.md](docs/configuring-dns.md).
|
||||
|
||||
If you would like to use a different domain, add the following to your configuration file (changing it to use your preferred domain):
|
||||
|
||||
```yaml
|
||||
matrix_server_fqn_hydrogen: "helium.{{ matrix_domain }}"
|
||||
```
