 # How to use?
 Parser implements stream which sequentially reads prolog terms provided by reader. By default, PrologParser is abstract class but there is pre-defined implementation GenericPrologParser for common cases.
 ```java
-    Reader reader = new StringReader("hello(world). some({1,2,3}). power(X,Y,Z) :- Z is X ** Y.");
-    ParserContext context = DefaultParserContext.of(ParserContext.FLAG_CURLY_BRACKETS, Op.SWI);
-    PrologParser parser = new GenericPrologParser(reader, context);
-    parser.forEach(System.out::println);
+Reader reader = new StringReader("hello(world). some({1,2,3}). power(X,Y,Z) :- Z is X ** Y.");
+ParserContext context = DefaultParserContext.of(ParserContext.FLAG_CURLY_BRACKETS, Op.SWI);
+PrologParser parser = new GenericPrologParser(reader, context);
+parser.forEach(System.out::println);
