+# Local Growth Rate
 
+A function that calculates the local growth rate from an existing ILI comparison
+
+## Input
+
+### Arguments
+
+- `org_id`: as string which should be a valid `uuid` for the organization
+- `project_id`: the id of the data project where the pipeline data is found
+- `pipeline_id`: an `array` of `strings` which should be valid UUIDs for pipelines
+- `ili_comparison_id`: an `array` of `strings` which should be valid UUIDs an ILI comparison sequence
+
+## Creating the function on the platform
+
+To create this function on the platform using the `cli` set up the port forwarding as shown in README.
+
+Then run the following command to create the function.
+
+```bash
+cargo run functions create \
+  -f functions/acr_local_growth_rate \
+  -d "Runs the local growth rate calculation based of a previous ILI comparison" \
+  -i org_id=string \
+  -i project_id=string \
+  -i pipeline_id=array \
+  -i ili_comparison_id=array
+```
+
+## Testing the function locally
+
+You can run and test the function locally by running
+
+```bash
+cargo run
+```
+
+Then you can check it work with `curl` as follows
+
+```bash
+curl localhost:8080 -d $(jq '. | tojson' functions/acr_local_growth_rate/example_input.json)
+```
