 1. Prepare your local development environment with following dependencies:
-   - python 3.10 or above
+   - python 3.10
    - docker
    - make
    - git
 
 2. As the app service will use default Message Bus trigger to consume events from EdgeX MessageBus, we have to run up EdgeX core services and device-virtual service to simulate the EdgeX events in your local environment. The easiest way to run up EdgeX services is through script available from https://github.com/edgexfoundry/edgex-compose:
    - `git clone https://github.com/edgexfoundry/edgex-compose.git`
    - switch into the `edgex-compose/compose-builder` directory
-   - `make run no-secty ds-virtual mqtt-bus keeper`
+   - `make run no-secty ds-virtual`
 
 3. By the completion of above step, you will have EdgeX core services, device-virtual service, and an MQTT broker running as docker container in your local environment, and you can examine their running status by using command: `docker ps -a`. Note that the running device-virtual service will periodically generate EdgeX events and publish them to EdgeX message bus, and you can observe those EdgeX events by using following command:
    - `docker exec edgex-mqtt-broker mosquitto_sub -v -t 'edgex/events/#'`
 
 4. Now we have EdgeX services up and running, the next step is to copy contents of this repository to your local environment by using following command:
-   - `git clone https://github.com/IOTechSystems/app-functions-sdk-python.git`
+   - `git clone https://github.com/edgexfoundry/app-functions-sdk-python.git`
 
 5. Switch into the `app-functions-sdk-python` directory
 
 6. Examine the code of `app-service-template/main.py` to understand how to write a custom application service using the App Functions Python SDK.

 12. Once the app-new-service is running, it will consume EdgeX events from the EdgeX message bus, filter for events coming from **Random-Integer-Device**, and then re-publish the events to an external MQTT broker **test.mosquitto.org** via **test_topic** topic. To observe those events being published to **test.mosquitto.org**, you can use following command:
