 ### Plugins
 
-You can find official plugins at https://github.com/aroz-online/zoraxy-official-plugins
-
-Place your plugins inside the volume `/path/to/zoraxy/plugin/:/opt/zoraxy/plugin/` (Adjust to your actual install location). Any plugins you have added will then be built and used on the next restart.
-
-> [!IMPORTANT]
-> Plugins are currently experimental.
+Zoraxy includes a (experimental) store to download and use official plugins right from inside Zoraxy, no preparation required.
+For those looking to use custom plugins, build your plugins and place them inside the volume `/path/to/zoraxy/plugin/:/opt/zoraxy/plugin/` (Adjust to your actual install location).
 
 ### Building
 
 To build the Docker image:
   - Check out the repository/branch.
-  - Copy the Zoraxy `src/` and `example/` directory into the `docker/` (here) directory.
+  - Copy the Zoraxy `src/` directory into the `docker/` (here) directory.
   - Run the build command with `docker build -t zoraxy_build .`
   - You can now use the image `zoraxy_build`
     - If you wish to change the image name, then modify`zoraxy_build` in the previous step and then build again.

+# Zoraxy Plugin
+
+## Overview
+This module serves as a template for building your own plugins for the Zoraxy Reverse Proxy. By copying this module to your plugin mod folder, you can create a new plugin with the necessary structure and components.
+
+## Instructions
+
+1. **Copy the Module:**
+    - Copy the entire `zoraxy_plugin` module to your plugin mod folder.
+
+2. **Include the Structure:**
+    - Ensure that you maintain the directory structure and file organization as provided in this module.
+
+3. **Modify as Needed:**
+    - Customize the copied module to implement the desired functionality for your plugin.
+
+## Directory Structure
+ zoraxy_plugin: Handle -introspect and -configuration process required for plugin loading and startup
+ embed_webserver: Handle embeded web server routing and injecting csrf token to your plugin served UI pages
