 ## Implementation
 
-NOTE: The following implementation steps have been developed and tested using this [Docker image](https://github.com/fabiocicerchia/nginx-lua).
+NOTES: 
+  - The following implementation steps have been developed and tested using this [Docker image](https://github.com/fabiocicerchia/nginx-lua).
+  - The following example uses `./usr/queueit` as the base path for storing all the Queue-it related files. Review and modify it to your needs.
 
-1) Copy the handler file and the following two folders from this repository to your NGINX filesystem. In the following example we will use `./usr/queueit` as the base path.
-    * [KnownUserNginxHandler.lua](https://github.com/queueit/KnownUser.V3.Lua/blob/master/Handlers/KnownUserNginxHandler.lua) -> `./usr/queueit/KnownUserNginxHandler.lua`
-    * [SDK](https://github.com/queueit/KnownUser.V3.Lua/tree/master/SDK) -> `./usr/queueit/SDK`
-    * [Helpers](https://github.com/queueit/KnownUser.V3.Lua/tree/master/Helpers) -> `./usr/queueit/Helpers`
-    
 
-2) Update or add the `lua_package_path` configuration option in your `nginx.conf` to include the new paths. Make sure to keep `;;` in the end which means default path:
+### 1. Copy the necessary files to your NGINX filesystem
 
-    ```
-    http {
-      lua_package_path "./usr/queueit/?.lua;./usr/queueit/SDK/?.lua;./usr/queueit/Helpers/?/?.lua;;";
-    }
-    ```

+- [SDK](https://github.com/queueit/KnownUser.V3.Lua/tree/master/SDK) -> `./usr/queueit/SDK`
+- [Helpers](https://github.com/queueit/KnownUser.V3.Lua/tree/master/Helpers) -> `./usr/queueit/Helpers`
+
+Copy the main handler script:

+- [Handlers/KnownUserNginxHandler.lua](https://github.com/queueit/KnownUser.V3.Lua/blob/master/Handlers/KnownUserNginxHandler.lua) -> `./usr/queueit/KnownUserNginxHandler.lua`

+ 
+### 2. Update the package paths
+
+Update or add the `lua_package_path` configuration option in the `http` section of your main configuration file (typically `nginx.conf`) to include the new paths you created in Step 1. Make sure to keep `;;` in the end which means default path:
+
+```
+http {
+  lua_package_path "./usr/queueit/?.lua;./usr/queueit/SDK/?.lua;./usr/queueit/Helpers/?/?.lua;;";
+}
+```
+
+
+### 3. Add the Queue-it handler to a specific location 
 
-3) Then update the configuration file relative to the location you want to be protected by Queue-it (`conf.d/default.conf` or similar):

+## Request body trigger (advanced)
 Nginx handler (incl. Lua SDK) supports triggering on request body content. Example could be a POST call with specific item ID where you want end-users to queue up for.
 You will need to contact queue-it support if this functionality is needed, so it can be enabled on your GO Queue-it platform account.
 When enabled you also need to add extra settings to `location` in `conf.d/default.conf`:
