 ### Install the debugger on the server
 
->Try out the Docker image on [Docker Hub](https://hub.docker.com/repository/docker/galien0xffffff/postgres-debugger/general) with a ready to use enhanced debugger (versions 11 to 15).  
-Images are based on the official postgres image and are available for amd64 and arm64 architectures. 
-> [Docker Image](/docker/Dockerfile) | [Readme](/docker/README.md)
+You can use the plugin with the standard pldbgapi extension, but you will not be able to inspect every variable type.  
+To get the full experience, you can use an [enhanced version](https://github.com/ng-galien/pldebugger) with the plugin.  
 
+You can compile the extension from the source code or use one of the [Docker images](https://hub.docker.com/repository/docker/galien0xffffff/postgres-debugger/general) available.
+
+> The Docker image is based on the official PostgreSQL image and includes the debugger extension, from version 11 to 16 for amd64 and arm64.
+> To build your own image, you can use the [Dockerfile](https://github.com/ng-galien/pldebugger/tree/print-vars/docker) provided.
 
 ```shell
-docker run -p 5514:5432 --name PG14-debug -e POSTGRES_PASSWORD=postgres -d galien0xffffff/postgres-debugger:14
+docker run -p 5515:5432 --name PG15-debug -e POSTGRES_PASSWORD=postgres -d galien0xffffff/postgres-debugger:15
 ```
 
 Or install the [debugger](https://www.pgadmin.org/docs/pgadmin4/development/debugger.html) binaries on  your machine.
 
+## Server Configuration
+
+To ensure the debugger shared libraries are correctly configured on your PostgreSQL server, follow these steps:
+
+1. **Check if the shared library is loaded**:
+   Run the following SQL command to verify if the `pldbgapi` extension is loaded:
+
+   ```sql
+   SELECT * FROM pg_extension WHERE extname = 'pldbgapi';
+   ```
+
+   If the extension is not listed, you need to install it.
+
+2. **Verify the shared library path**:
+   Ensure that the `shared_preload_libraries` parameter in your `postgresql.conf` file includes `pldbgapi`. You can check this by running:
+
+   ```sql
+   SHOW shared_preload_libraries;
+   ```
+
+   If `pldbgapi` is not included, add it to the `postgresql.conf` file:
+
+   ```conf
+   shared_preload_libraries = 'pldbgapi'
+   ```
+
+   After making changes, restart the PostgreSQL server.
+
+3. **Check the installation of the debugger extension**:
+   Run the following command to ensure the debugger extension is installed in the correct schema:
+
+   ```sql
+    SELECT * FROM pg_extension;
+   ```
+
+   Look for `pldbgapi` in the list of installed extensions. If it is not present, install it using:
+
+   ```sql
+   CREATE EXTENSION IF NOT EXISTS pldbgapi;
+   ```
+
+By following these steps, you can confirm that the debugger shared libraries are properly configured on your PostgreSQL server.
