+## Use the plugin before the release?
+
+I am still actively developing this plugin, but I have not yet submitted it to Obsidian.
+However, you can still use the plugin using **BRAT**:
+
+1. Open Obsidian and go to the community plugins tab.
+2. Search for **BRAT** and install it.
+3. Click on the **Add Beta Plugin** button.
+4. Paste the plugin link: https://github.com/FlorianWoelki/obsidian-better-recall
+5. Click **Add Plugin**.
