 #### NGINX plugin associated libraries
 The NGINX plugin uses these libraries: shmem_ipc, compression_utils, and nginx_attachment_util.
+They can be found under the `lib` directory in the `<output path>` given to the CMake.
+
+#### Deploying the attachment on an existing nginx server
+
+1. Copy the associated libraries to /usr/lib on your existing nginx server
+2. Copy the nginx attachment file lib/libngx_module.so to the following path on your existing nginx server: /usr/lib/nginx/modules/
+3. Load the attachment on your nginx by adding the following command to the main nginx.conf file: 
+   `load_module /usr/lib/nginx/modules/libngx_module.so;`
+4. Restart your nginx server.
+
+### Compiling the attachment code and creating a docker image for an existing nginx/ingress-nginx docker
+
+This step requires Docker to be installed on your compilation environment
+
+1. Clone this repository
+3. Run Configuration script with the required docker image name and tag
+4. Run CMake command
+5. Run make command
+
+```bash
+ $ git clone https://github.com/openappsec/attachment.git
+ $ ./attachments/nginx/ngx_module/nginx_version_configuration.sh --docker <input docker image> build_out
+ $ cmake -DCMAKE_INSTALL_PREFIX=build_out -DOUTPUT_DOCKER_IMAGE=<output docker image> .
+ $ make install
+ $ make docker
+```
+
+Later on, you can push the image to your own registry and use it as needed.
+
+For deployment on docker you can deploy it using the same docker command you used before with regular nginx container, just make sure to add the parameter `--ipc=host`.
