-successeur de botEnTrain mais pour BlueSky
+#botEnSky
+
+botEnSky is a bot [BlueSky social app](https://bsky.app/)
+
+- status: **Started May 16, work in progress**
+
+It is a NodeJs application that relies on [bsky api](https://docs.bsky.app/).
+
+The goal is to be the worthy successor to [@botentrain1](https://twitter.com/botentrain1) ([src](https://github.com/boly38/botEnTrain)) but for BlueSky.
+
+The search is not the same between the two networks (X, Bsky), so we will have to think about new designs, but the first function considered is plant identification
