+## Analytics
+We have recently introduced a little frontend where you can show with a chart you points trend. The script will spawn a Flask web-server on your machine where you can select binding address and port.
+The chart provides some annotation to handle the prediction and watch strike events. Usually annotation are used to notice big increase / decrease of points. If you want to can disable annotations.
+On each (x, y) points Its present a tooltip that show points, date time and reason of points gained / lost. This web page was just a funny idea, and it is not intended to use for a professional usage.
+If you want you can toggle the dark theme with the dedicated checkbox.
+
+| Light theme | Dark theme |
+| ----------- | ---------- |
+| ![Light theme](./assets/chart-analytics-light.png) | ![Dark theme](./assets/chart-analytics-dark.png) |
+
+For use this feature just call the `analytics` method before start mining. Read more at: [#96](https://github.com/Tkd-Alex/Twitch-Channel-Points-Miner-v2/issues/96)
+The chart will be autofreshed each `refresh` minutes. If you want to connect from one to second machine that have that webpanel you have to use `0.0.0.0` instead of `127.0.0.1`.
+```python
+from TwitchChannelPointsMiner import TwitchChannelPointsMiner
+twitch_miner = TwitchChannelPointsMiner("your-twitch-username")
+twitch_miner.analytics(host="127.0.0.1", port=5000, refresh=5)   # Analytics web-server
+twitch_miner.mine(followers=True, blacklist=["user1", "user2"])
+```

 ## Migrating from an old repository (the original one):
 If you already have a `twitch-cookies.pkl` and you don't want to log in again, please create a `cookies/` folder in the current directory and then copy the .pkl file with a new name `your-twitch-username.pkl`
 ```
