+## Understanding auto-instrumentation scope
+
+Auto-instrumentation automatically captures telemetry for the frameworks and libraries listed on this page. However, it cannot instrument:
+
+- Custom or proprietary frameworks and libraries
+- Closed-source components without instrumentation support
+- Application-specific business logic
+
+If your application uses technologies not covered by auto-instrumentation, you have two options:
+
+1. **Native OpenTelemetry support** — Some frameworks and libraries include built-in OpenTelemetry instrumentation provided by the vendor.
+2. **Manual instrumentation** — Use the [OpenTelemetry API](manual-instrumentation.md) to add custom spans, metrics, and logs for unsupported components.

+### TLS connections
+
+EDOT Android supports TLS connections to OTLP endpoints and OpAMP (central configuration) endpoints when the server uses a TLS certificate signed by a trusted Certificate Authority (CA).
+
+:::{warning}
+Self-signed certificates are **not supported**. If your endpoint uses a self-signed certificate, EDOT Android will not be able to establish a secure connection. Ensure your server uses a certificate issued by a publicly trusted CA or an internal CA that is trusted by the device.

 ### Intercept export request headers
 
 You can provide an interceptor for the signals' export request headers, where you can read or modify them if needed.
