-#### Segment Identify Call
+##### Segment Identify Call
 
 The `identify` method of Segment permits identifying an instance by sending a unique identifier. It groups the information of a MeiliSearch binary such as `system`, `stats`, and general properties related below in this specification.
 
 The segment identify call is only sent after the first hour if the instance is still running. At the first launch, MeiliSearch sends a `Launched` event on an instance ID equal to `total_launch` in order to avoid tracking instances usage for nothing when they could be shut down and never restarted.

 Errors occurring when sending metrics to Segment should be silent. In general, the impact of data collection should be minimized as much as possible concerning performance and be entirely transparent for the user during its use.
