-# 382f4a4ad8624fcea82cb2d0b77b7509
+# Long term corrosion rate.
 
+This is calculated using a chosen ILI report and the growth rate is calculated on the
+assumption that the growth rate has been constant since the creation of the pipeline.
+
+At it's most fundamental the calculation is simply `p / t` where `p` is the property (either
+the depth or length of the anomaly) and `t` is the time gap between the creation of the
+pipeline and the ILI report date.
+
+## 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_id`: an `array` of `strings` which should be valid UUIDs for ili sequences
+- `aggregation`: an `string`  each value should be one of the following
+  - `segment`
+  - `pipeline`
+  - `girth_weld`
+  - `every_1_km`
+  - `every_5_km`
+  - `every_10_km`
+
+## 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_long_term_corrosion_growth_rate \
+  -d "Run the long term corrosion growth rate calculation on using the provided ILI" \
+  -i org_id=string \
+  -i project_id=string \
+  -i pipeline_id=array \
+  -i ili_id=array \
+  -i aggregation_method=object
+```
+
+## 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_long_term_corrosion_growth_rate/example_input.json)
+```
