 * **Database Setup (using PostgreSQL)**:
-    * Installation: 
+    * Linux
+        * Installation: 
+            ```bash
+            sudo apt-get install postgresql-client
+            sudo apt-get install postgresql
+            ```
+        * Initialization:
+            
+            Switch to the **postgres** user and launch **psql** console
+            ```bash
+            sudo su - postgres
+            psql
+            ```
+            
+            Then, create a new user role:
+            ```bash
+            CREATE ROLE <user> WITH LOGIN PASSWORD '<password>';
+            ALTER ROLE <user> SUPERUSER;    
+            ```
+    * Windows
+        * click `Download the installer` in [PostgreSQL](https://www.postgresql.org/download/windows/).  
+        * Run the downloaded installation package as administrator, then click `next` continuously.  
+        * Open PowerShell:
         ```bash
-        sudo apt-get install postgresql-client
-        sudo apt-get install postgresql
-        ```
-    * Initialization:
-
-      Switch to the **postgres** user and launch **psql** console:
+            cd C:\Program Files\PostgreSQL\14\bin
+        ```   
+        The exact path will vary depending on your PostgreSQL location.  
+        * Then in PowerShell:
         ```bash
-        sudo su - postgres
-        psql
-        ```
-      Then, create a new user role:
+            .\psql -U postgres    
+        ```   
+        Input the password you set in the previous installation. If PowerShell shows `postgres=#`, it indicates a successful connection.
+        * Create a new user role:
         ```bash
         CREATE ROLE <user> WITH LOGIN PASSWORD '<password>';
         ALTER ROLE <user> SUPERUSER;    
         ```
