+# Arc Ingester
+
+Read the JSON export from the [Arc](https://www.bigpaua.com/arcapp) app and ingest it into a postgresql database. This
+is designed to be run as a cron job or launchctl jjob to keep the database up to date with the latest data from the app.
+
+## Requirements
+
+- The Arc app installed on your iPhone (or possibly other iOS devices?)
+- The app set to export data
+- A postgresql database to ingest the data into
+
+## Installation
+
+Currently, the ingester is not available as a binary, so you will need to build it from source. You will need to have
+[Rust](https://www.rust-lang.org) installed to do this.
+
+```shell
+cargo install --git https://github.com/joshuacoles/arc-ingester
+```
+
+## Running
+
+The ingester is a command line tool that takes the following arguments,
+
+```shell
+arc-ingester --root "~/Library/Mobile Documents/iCloud~com~bigpaua~LearnerCoacher/Documents" --db "postgresql://localhost/arc"
+```
+
+see `arc-ingester --help` for more information.
