 ## Guide for Contributing to Multiple Services
-We rely on docker-compose to start all services. If you are contributing to multiple services, you could just comment out the services you'd like to start from source code and change the `env` variables to point to the services you started by yourself.

 ### Example: Contributing to the [Wren UI Service](#wren-ui-service) and [Wren Engine Service](#wren-engine-service)
 If you are contributing to both the [Wren UI Service](#wren-ui-service) and [Wren Engine Service](#wren-engine-service), you should comment out the `wren-engine` service in the `docker/docker-compose-dev.yml` file (note that the UI service is already excluded from `docker/docker-compose-dev.yml`). Then, adjust the environment variables in your `.env` file to point to the services you have started manually. This will ensure that your local development environment correctly interfaces with the services you are working on.

 ## :electric_plug: Creating a New Data Source Connector
 
-To create a new data source connector, you will need to make changes to both the front-end and back-end of Wren UI, as well as the Wren Engine.
+To develop a new data source connector, you'll need to modify both the front-end and back-end of the Wren UI, in addition to the Wren Engine.
 
 Below is a brief overview of a data source connector:

 The UI is primarily responsible for storing database connection settings, providing an interface for users to input these settings, and submitting them to the Engine, which then connects to the database.
 
-The UI needs to be aware of the connection information it must store, as determined by the Engine. Therefore, the implementation sequence would be as follows:
