### Assumptions

This example makes the following assumptions:

- __Application Root URL:__ `https://firezone.{{< sitevar name="domain" nojs="example.com" >}}/`
- __Authelia Root URL:__ `https://{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}/`
- __Client ID:__ `firezone`
- __Client Secret:__ `insecure_secret`
- __Config ID (Firezone):__ `authelia`:
    - This option determines the redirect URI in the format of
      `https://firezone.{{< sitevar name="domain" nojs="example.com" >}}/auth/oidc/<Config ID>/callback`.
      This means if you change this value you need to update the redirect URI.

Some of the values presented in this guide can automatically be replaced with documentation variables.
