 All variables are listed below (see also `defaults/main.yml`).

-# defaults file for outline
+### Outline Core Variables
 
+Outline requires a couple of secrets for data encryption:
+
+```yml
 outline_secret_key: 'changeme'
 outline_utils_secret: 'changeme'
+```
 
+You also need to specify the deployment type. Usually it's `production`
 
-outline_setup_path: '~/outline'
+```yml
 outline_deployment: ''
+```
 
-outline_port: 3000
-outline_url: "http://localhost:{{ outline_port }}"
-outline_force_https: "false"
-outline_enable_updates: "false"
-outline_cdn_url: 
+You also need to define how you access outline:
 
-outline_debug: "cache,presenters,events,emails,mailer,utils,multiplayer,server,services"
+- `outline_port` is the port mapping in Docker. Outline runs at port 3000, which is alos the default
+- `outline_url` is the public URL where we see Outline. If you use reverse proxy mapping, put the URL of the reverse proxy (in my case *[this one](https://wiki.home.laurivan.com)*).
+- `outline_force_https` will run with HTTPS if true. you can define it as *false* If you're behind a proxy or you don't have a certificate. It defaults to `false`.
+- `outline_enable_updates` will enable updates if true. Please read [the documentation](https://app.getoutline.com/s/770a97da-13e5-401e-9f8a-37949c19f97e/) for what this implies (e.g. telemetry)
+- Define `outline_cdn_url` if you have a CDN. Defaults to *empty*
 
+**Note**: `outline_url` will define the authentication redirect url for e.g. authentik
+
+You can define which debug messages to be logged via `outline_debug`.
+
+### Storage
+
+Following values are defined for the docker-compose:
+
+```yml
 outline_volume_base: "/mnt/outline"
+outline_setup_path: '{{ outline_volume_base }}/config'
 outline_volume_redis: "{{ outline_volume_base }}/redis"
 outline_volume_db: "{{ outline_volume_base }}/db"
 outline_volume_s3: "{{ outline_volume_base }}/s3"
+```
 
+Please note that `outline_volume_db` and `outline_volume_s3` are actually created only if local posstgres and fake_s3 containers are created by configuration below.
+
+You can specify a logo too via `outline_team_logo_url`. By default this is empty.
+
+You can also change the default language via `outline_language`. The role defaults the language to *en_US*.
+
+### Authentication
+
+Outline authentication can happen via:
+
+- OIDC
+- Google authentication
+- Slack
+
+You need to define at least one of them.
+
+#### OIDC
+
+OIDC parameters are
+
+```yml
 oidc_client_id:
 oidc_client_secret:
 oidc_auth_uri:
 oidc_token_uri:
 oidc_userinfo_uri:
+```
 
+Your authentication app should provide you all the above. I use something along the lines:
+
+```yml
+oidc_client_id: "changeme"
+oidc_client_secret: "changeme"
+oidc_auth_uri: "https://sso.laurivan.com/application/o/authorize/"
+oidc_token_uri: "https://sso.laurivan.com/application/o/token/"
+oidc_userinfo_uri: "https://sso.laurivan.com/application/o/userinfo/"
+oidc_username_claim: "preferred_username"
+```
+
+**Note**: you will probably need to provide the redirect URL to the authentication application. For Authentik, you can find it in the **Provider** for the specific application.
+
+#### Google ID
+
+You need to define:
+
+```yml
 outline_google_client_id:
 outline_google_client_secret:
+```
+
+#### Slack
+
+You need to define
+
+```yml
 outline_slack_client_id:
 outline_slack_client_secret:
+```
 
-# If the db_host is not "postgres", then we assume the
-# db is external and not spin up the docker container
+### Database
+
+You need to assign a database to Outline. This role allows you to launch Postgres in a container via:
+
+```yml
 outline_db_schema: "postgres"
 outline_db_host: "postgres"
 outline_db_port: "5432"
 outline_db_user: "postgres"
 outline_db_password: "changeme"
 outline_db: "outline"
+```
 
-# By default, PostgreSQL is not secured. If you have a secure
-# database instance, replace the content below with "enable".
-outline_db_ssl: "disable"
+If the db_host is not "postgres", then we assume the db is external and not spin up the docker container.
 
-# Spin up the fake S3 only if "fake_s3" is true
+By default, PostgreSQL is not secured. If you have a secure database instance, set the `outline_db_ssl` variable to "enable".
+
+### S3
+
+We define the following variables:
+
+```yml
 outline_fake_s3: true
 outline_fake_s3_port: 4569
 outline_aws_access_key_id:
@@ -68,17 +140,34 @@ outline_aws_s3_upload_bucket_name: outline-bucket
 outline_aws_s3_upload_max_size: "26214400"
 outline_aws_s3_force_path_style: "true"
 outline_aws_s3_acl: "private"
+```
 
+You need S3 (or S3-like) storage for e.g. uploaded files. By default, the role spins up the fake S3 only if `fake_s3` variable is true.
+
+I use [MinIO](https://min.io/) with something like:
+
+```yml
+outline_fake_s3: ""

+### Email
+
+Outline can send notification emails if you set up the SMTP variables:
+
+```yml
 outline_smtp_host:
 outline_smtp_port:
 outline_smtp_username:
 outline_smtp_password:
 outline_smtp_from_email:
