+# Bluesky Users
+
+## Overview
+
+This is a simple app that displays the total number of users on the [Bluesky](https://bsky.social/) social network.
+
+Data is gathered from the website https://bsky-users.theo.io.
+
+The app displays an animation of the user count increasing, according to a growth rate returned from the aforementioned website.
+
+---
+
+## Configuration (Schema)
+
+The app supports some configuration options like changing the user count color and using dots instead of commas as thousands separator.
+
+---
+
+## API Details
+
+There is a single and unauthenticated API being used: https://bsky-users.theo.io/api/stats.
+
+We are not sure if there is any kind of rate limiting implemented, but results are cached for 15 minutes using the http module native caching mechanism.
+
+---
+
+## Error Handling
+
+The app has safeguards in place to identify potential errors and always display something on the screen. For instance, a non 200 response from the API will be handled and a message will be shown on the screen.
+
+---
+
+## Future Improvements
+
+There's nothing left to add here since the API only returns the user count and the growth rate.
