+
+For Windows:
+
+```cmd
+netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=41185 connectaddress=localhost connectport=41184
+```
+
+For Linux:
+
+```bash
+socat tcp-listen:41185,reuseaddr,fork tcp:localhost:41184
+```
+
+### Markdown Formatting
+You can configure Markdown formatting by navigating to **Export Highlights > Choose Formats and Services > Markdown**.
+
+## Usage
+There are two export options are available:
+1. Export all notes in this book
+2. Export all notes in your library
+
+Upon exporting this plugin will export notes to all enabled targets.
