 ## Deployment options
 
 Infisical can be deployed on a Linux VM with docker-compose. We're rolling out more specific deployment options for DigitalOcean, AWS, GCP, and Azure soon.
+
+## Telemetry
+
+Infisical collects telemetry data about general usage.
+
+The data helps us understand how the product is doing and guide our product development to create the best possible platform; it also helps us demonstrate growth for investors as we support Infisical as open-source software.
+
+To opt out of telemetry, you can set `TELEMETRY_ENABLED=false` within the [environment variables](./configuration/envars).
