+
+## What does this script do
+
+When using the V2 metric submission API endpoint (https://docs.datadoghq.com/api/latest/metrics/#submit-metrics) users cannot specify multiple hots tags on the same `series` parameter.
+
+Instead, we need to define a seperate `series` for each hostname.
+
+This could be a tedious process especially if we have a large number of hosts with different metric value and timestamps.
+
+`generate.sh` will automatically create a ready to use script that contains the proper API call to submit multiple data points for multiple hosts in different timestamps. 
+
+## Instructions
+
+Before launching the `generate.sh` script, make sure to fill up the `data.csv` file with the list of host names, their metric values and their timestamp accordingly.
+
+Once done you can launch the `generate.sh` script which will automatically generate another script `send.sh` which could be executed to submit the metrics. 
+
+> **_NOTE:_** Please make sure to replace the API key and the endpoint URL accordingly.
