 The MedTech service processes device data in five stages:
 
-1. **Ingest** - The MedTech service asynchronously loads the device messages from the event hub at high speed.
+1. **Ingest** - The MedTech service asynchronously reads the device message from the event hub at high speed.
 
 2. **Normalize** - After the device message has been ingested, the MedTech service uses the device mapping to streamline and convert the device data into a normalized schema format.
 
 3. **Group** - The normalized data is then grouped by parameters to prepare it for the next stage of processing. The parameters are: device identity, measurement type, time period, and (optionally) correlation ID.
 
 4. **Transform** - When the normalized data is grouped, it's transformed through the FHIR destination mapping and is ready to become FHIR Observations.
 
-5. **Persist** - After the transformation is done, the new data is sent to the FHIR service and persisted as FHIR Observations.
