 # Introduction
 
-QoA4ML consists of a set of utilities and specs for supporting quality of analytics in ML and data intensive (micro)services. Especially, we focus on services and systems of services across edge-cloud continuum, which are built as a composition of (micro)services.

 ## QoA4ML Specification
 
 The design of QoA4ML specification is in [language](language/)
 
-## QoA4ML Utilities
+## QoA4ML Probes
 
-Developers can call many functions from a QoAClient and QoA4ML's [utilities](qoa4ml_lib/utils.py) to evaluate/report ML-specific attributes (e.g., data quality, inference performance), build the quality reports, and send them to the observation services.
-The QoAClient can be initiated with various configurations for specifying observation server and communication protocols (e.g., messaging) in different formats (e.g., json and yaml).
-
-The detail documents for QoA4ML utilization is presented in [qoa4ml_lib](qoa4ml_lib/)
+We include [different probes](src/qoa4ml/probes/) for measuring quality of data, computing resource performance, etc.
 
-> For a local build and use QoA4ML one can do:
+## 
 
-```bash
-$python3 -m pip install build
-$cd qoa4ml_lib/
-$python -m build
-```
