 We can edit the database URL and add the database user and password if needed:
 
 ```
 # It follows the format below:
-BOOKSHELF_DATABASE_URL="[ADAPTER]://[DATABASE_USER]:[DATABASE_USER_PASSWORD]@[HOST]:[PORT]/[DATABASE_NAME]"
+DATABASE_URL="[ADAPTER]://[DATABASE_USER]:[DATABASE_USER_PASSWORD]@[HOST]:[PORT]/[DATABASE_NAME]"
 
 # Example:
-BOOKSHELF_DATABASE_URL="postgres://user:password@localhost:5432/bookshelf_development"
+DATABASE_URL="postgres://user:password@localhost:5432/bookshelf_development"
 ```
 The placeholders **_user_** and **_password_** should be replaced with the correct credentials.
