 loosely based on [this](https://github.com/turt2live/matrix-appservice-webhooks/blob/master/README.md)
 
 1. All you basically need is to adjust your `inventory/host_vars/matrix.<domain-name>/vars.yml`:
-    ```yaml
-    matrix_appservice_webhooks_enabled: true
-    matrix_appservice_webhooks_api_secret: '<your_secret>'
-    ```
+
+```yaml
+matrix_appservice_webhooks_enabled: true
+matrix_appservice_webhooks_api_secret: '<your_secret>'
+```
 
 2. In case you want to change the verbosity of logging via `journalctl -fu matrix-appservice-webhooks.service`
 you can adjust this in `inventory/host_vars/matrix.<domain-name>/vars.yml` as well.

-*Note*: default value is: `info` and availabe log levels are : `info, verbose`
 
-    ```yaml
-    matrix_appservice_webhooks_log_level: '<log_level>'
-    ```
+*Note*: default value is: `info` and availabe log levels are : `info`, `verbose`
+
+```yaml
+matrix_appservice_webhooks_log_level: '<log_level>'
+```
 
 3. If you've already installed Matrix services using the playbook before, you'll need to re-run it (`--tags=setup-all,start`). If not, proceed with [configuring other playbook services](configuring-playbook.md) and then with [Installing](installing.md). Get back to this guide once ready.
 
 4. Invite the bridge bot user to your room:
-    - either with:
-      ```
-      /invite @_webhook:<domain.name>
-      ```
-        *Note*: Make sure you have administration permissions in your room
+
+    - either with `/invite @_webhook:<domain.name>` (*Note*: Make sure you have administration permissions in your room)
+
     - or simply add the bridge bot to a private channel (personal channels imply you being an administrator)
 
 5. Send a message to the bridge bot in order to receive a private message including the webhook link.
-    ```
-    !webhook
-    ```
+```
+!webhook
+```
 
 6. The JSON body for posting messages will have to look like this:
-    ```
-    {
-        "text": "Hello world!",
-        "format": "plain",
-        "displayName": "My Cool Webhook",
-        "avatarUrl": "http://i.imgur.com/IDOBtEJ.png"
-    }
-    ```
-   - You can test this via curl like so:
-     ```
-     curl --header "Content-Type: application/json" \
-     --data '{
+```json
+{
     "text": "Hello world!",
     "format": "plain",
     "displayName": "My Cool Webhook",
     "avatarUrl": "http://i.imgur.com/IDOBtEJ.png"
-     }' \
-     <the link you've gotten in 5.>
-     ```
+}
+```
