 [![Build](https://github.com/somleng/somleng-integrations/actions/workflows/skyetel.yml/badge.svg)](https://github.com/somleng/somleng-integrations/actions/workflows/skyetel.yml)
 
-This integration connects [Skyetel](https://skyetel.com/) to [Somleng](https://www.somleng.org/docs.html).
-
-## Features
-
-* Automatically purchase DIDs from Skyetel and add them to your Somleng carrier account.
+This integration runs on a schedule and automatically orders DIDs from [Skyetel](https://skyetel.com/) and adds them to [Somleng](https://www.somleng.org/docs.html). It keeps the stock levels between `MIN_STOCK` and `MAX_STOCK` for each city configured in the `supported_cities.csv` file.
 
 ## Configuration
 
-Add configuration parameters here.
