 ## Overview
 
-This integration collects data from Traefik and checks its health.
+This integration collects data from Traefik in order to check its health and monitor:
+
+- Errors logs (4xx codes, 5xx codes)
+- Number of requests
+- Number of bytes exchanged
+
 
 ## Setup
 
+### Installation
+
+The Traefik check is included in the Datadog Agent package. To start gathering your Traefik metrics and logs, you need to [install the Datadog Agent][1]
+
 ### Configuration
 
-Create a `traefik.yaml` in the Datadog Agent's `conf.d` directory.
+1. Edit the `traefik.d/conf.yaml` file in the `conf.d/` folder at the root of your [Agent's configuration directory][7] to start collecting your Traefik [metrics](#metric-collection) and [logs](#log-collection).
+  See the [sample traefik.d/conf.yaml][8] for all available configuration options.
+
+2. [Restart the Agent][3]
 
 #### Metric Collection

 [Restart the Agent][3] to begin sending Traefik metrics to Datadog.
 
+#### Log Collection
+
+**Available for Agent >6.0**
+
+By default [Traefik logging][9] feature logs to stdout. This should not be changed for containerised version as the Datadog Agent is able to collect logs directly from container `Stdout`/`Stderr`.
+
+To configure Traefik to log into a file simply add the following in the Traefik configuration file:
+
+```
+[traefikLog]
+  filePath = "/path/to/traefik.log"
+```
+
+The [common Apache Access format][10] is used by default and is supported by this integration.
+
+1. Collecting logs is disabled by default in the Datadog Agent. Enable it in your `datadog.yaml` file with:
+
+      ```yaml
+      logs_enabled: true
+      ```
+
+
+2.  Add this configuration block to your `traefik.d/conf.yaml` file  at the root of your [Agent's configuration directory][7] to start collecting your Traefik logs:
+
+      ```yaml
+      logs:
+        - type: file
+          path: /path/to/traefik.log
+          source: traefik
+          service: traefik
+      ```
+
+* Change the `path` and `service` parameter values and configure them for your environment. 
+
+* [Restart the Agent][3]
+
 ### Validation
 
 [Run the Agent's `status` subcommand][4] and look for `traefik` under the Checks section:
