 Example:
-  ./semantika queryanswer --config=application.cfg.xml --query=query.txt -l 100
-  ./semantika rdb2rdf --config=application.cfg.xml --output=output.n3 -f N3
+  ./semantika queryanswer -c application.cfg.xml -l 100 -sparql 'SELECT ?x WHERE { ?x a :Person }'
+  ./semantika rdb2rdf -c application.cfg.xml -o output.n3 -f N3
 ```
 
 The tool serve two main functions as: (1) SPARQL query tool and (2) RDB2RDF export tool.
 
 SPARQL Query Tool

+Here are some examples on querying data in database using SPARQL. Note that when the `-c` is omitted then the system will search the default configuration `application.cfg.xml` at the classpath.
 
 * Simple data query

 User's Guide
 ------------
 
 1. [Download and unzip the latest release](https://github.com/obidea/semantika-cli/releases).
-2. Create your application-domain model. There are two input documents for declaring the specification, i.e.,
-  * `ontology.owl`: specifies the names or labels used in the application domain.
-  * `mapping.xml`: specifies the releation between the labels in ontology and data in database (e.g., Label 'Employee' is connected to records in column 'EMP_ID' in table 'EMPLOYEE_TNT_2010')
-3. Create the configuration file that points the location of the input domain documents and other application settings.
-4. Put the JDBC driver according to your database product.
+2. Create the application-domain model. There are two types of modelling documents, i.e., an OWL ontology document and mapping document(s). The ontology document is an optional.
+3. Create the configuration file. It specifies the location of the model documents and the database connection parameters.
+4. Place the proper JDBC driver inside the `jdbc/` folder
 5. Run the command provided by the tool.
