+## Product Mission
+
+**ZIOFA** (Zero Instrumentation Observability for Android) aims to implement observability use cases relevant to performance specified by our industry partner using eBPF. Examples include tracing long-running blocking calls, leaking JNI indirect references or signals like SIGKILL sent to processes, all without instrumenting the observed application itself.  
+The eBPF programs are loaded and unloaded using a **backend daemon** running as root that will collect metrics and send them to a client.  For displaying these metrics to the user, we are implementing an **on-device UI** that can display visualizations for these use cases and allow for configuration of the enabled use cases, but **using a decoupled Client SDK** so that future work may easily make the data accessible the external processing.
