 AWS lambda flow
 ===============
-1. User generates the benchmark result on their device.  
-`$ resctl-bench -r "$RESULT_JSON" --logfile=$LOG_FILE run iocost-tun`
-2. User uploads the result to aws lambda function url as:  
-`resctl-bench -r <RESULT_JSON>   upload --upload-url  <AWS lambda function URL>`  
+1. User generates the benchmark result on their device.
+`$ resctl-bench -r "$RESULT_JSON" --logfile=$LOG_FILE run iocost-tune`
+2. User uploads the result to aws lambda function url as:
+`resctl-bench -r <RESULT_JSON> upload --upload-url  <AWS lambda function URL>`
 e.g  
 `$resctl-bench --result resctl-bench-result_2022_07_01-00_26_40.json.gz upload --upload-url https://ygvr6jnjckwamfao5xztg6idiu0ukjeb.lambda-url.eu-west-1.on.aws`
 
 3. Lamda is tiggered automatically in AWS.
      - It saves the benchmark result to S3 bucket.
-     - Then create a issue in iocost-benchmark/iocost-benchmarks project using `iocost-issue-creater` github app.
+     - Then creates an issue in [iocost-benchmarks](https://github.com/iocost-benchmark/iocost-benchmarks) project using [iocost-issue-creater](https://github.com/apps/iocost-issue-creater) github app.
      - Issue contain a link to benchmark result stored in s3 bucket.
+     e.g https://github.com/iocost-benchmark/iocost-benchmarks/issues/88
 
+### Lambda workflow:
+Client uploads the benchmark result (above steps) -> AWS Lambda runs -> save result to s3 bucket -> Create github Issue with link of result stored in s3.
+Thereafter it's job of [iocost-benchmarks project](https://github.com/iocost-benchmark/iocost-benchmarks) to import and merge the results with existing database and generate final hwdb file.
