 1. Prepare a .pkl configuration file (see examples below).
 2. Add this artifact to your application's classpath.
-3. Reference the .pkl file in the JDBC URL.
+3. Reference the .pkl file and the parser type in the JDBC URL.
 
-The parser type is inferred from the file extension. In this case, it’s "pkl".
-If the file name doesn’t include an extension, you can specify the parser explicitly using the parser option.
+The parser type can be specified using the `parser` option. In this case, it’s "parser=pkl". 
+By default, the parser type is "json".
 All other options (like key, label, etc.) follow the same format as other providers.
 
 Example using the file configuration provider:
 
 ```java
-jdbc:oracle:thin:@config-file://{pkl-file-name}[?parser=pkl&key=prefix&label=value&option1=value1&option2=value2...]
+jdbc:oracle:thin:@config-file://{pkl-file-name}?parser=pkl[&key=prefix&label=value&option1=value1&option2=value2...]
