 # Synapse-ETL-Jobs
-The Synapse ETL jobs project maintains all the Python-based Glue job scripts respoonsible for moving 
-Synapse Warehouse data to S3 where it can be queried by Athena. 
-The scripts are deployed to S3, from where the Synapse Stack Builder can include them in a Glue
-CloudFormation stack it creates.
-For more information please see the [design documentation](https://sagebionetworks.jira.com/wiki/spaces/DW/pages/2732916846/Processing+Access+Records+using+AWS+High+Level+Design).
+[AWS Glue](https://docs.aws.amazon.com/glue/latest/dg/what-is-glue.html) is a cloud service that prepares data for analysis 
+through automated extract, transform and load (ETL) processes. The Glue job uses the scripts for the ETL process. 
+The Synapse-ETL-Jobs project maintains all the Python-based Glue job scripts. The Glue jobs are responsible for moving 
+Synapse warehouse json data to S3 in parquet format, which can be queried by Athena. The [Synapse-Stack-Builder](https://github.com/Sage-Bionetworks/Synapse-Stack-Builder) 
+project deploys these Python scripts to s3 and creates the Glue jobs. For more information please see

-# Local environment setup
-The project uses AWS Glue libraries and Python, and requires Docker.
-
-To install Python on MacOS use the command below, which requires Python version 3 to be installed. 
-PIP (PIP is a package manager for Python packages, or modules ) is included in python version 3.4 or later.
+# Local Python setup
+The project's scripts are Python-based. In order to make use of Python libraries and address syntax errors, 
+it's essential to have Python 3 installed, as Glue employs Python 3.
 
 ```
-brew install python
+brew install python@3.8
 ```
 
-The following steps build and run a Docker container.
+# Local test environment setup
+In order to execute the tests, the presence of Glue libraries is necessary. To address the dependencies related to Glue, 
+build a Docker container using the AWS Glue image to ensure the provisioning of essential prerequisites.
 
-Build image
+1. Install and start Docker. If you’re on Mac, you can download and install Docker Desktop (https://www.docker.com/products/docker-desktop). 
+Note that you’ll need to create a Docker account.
+2. Create a Docker project directory for your AWS Glue container. Name could be like ~/docker/AWSGlue
+3. In that directory, create a file called docker-compose.yml. Its contents should contain
+```
+version: '3.3'
+services:
+    aws-glue:
+        image: aws-glue
+        container_name: 'aws-glue'
+        ports:
+          - 8888:8888
+          - 4040:4040
+```
+4. In the same directory, run docker-compose up -d. This will launch a Docker container with the image.
 
+If you already have a docker container, run the following command to build the image.
 ```
 docker build -t aws-glue .
 ```
 
-To run tests use the following command. It will execute the test files, whose names start with test.
+To initiate tests, run the following command, which will execute the test files prefixed with 'test'.
 
 ```
-docker run -v ~/.aws:/home/glue_user/.aws -v  ${GITHUB_WORKSPACE}:/home/glue_user/workspace/  -e DISABLE_SSL=true --rm -p 4040:4040 -p 18080:18080  aws-glue -c "python3 -m pytest"
+docker run -v ~/.aws:/home/glue_user/.aws -v  ${LOCAL_WORKSPACE ../SageBionetworks/Synapse-ETL-Service}:/home/glue_user/workspace/  -e DISABLE_SSL=true --rm -p 4040:4040 -p 8888:8888  aws-glue -c "python3 -m pytest"
 ```
