-# Under very deep refactoring!
+# Preword
+
+During my development of Java prolog engine (JProl) I had developed parser to parse sources written in Edinburgh style, I decided to extract the module into separated project and 1.0.0 version was published. In 2018 I had decided to make deep refactoring and 2.0.0 version was published. The Parser allows build custom prolog parsers with support of operators and some modern prolog features.
+
+# Features
+
+It supports
+ - prolog operators
+ - line and block commentaries
+ - underline splitted numbers
+ - curly blocks
+
+# How to use?
+Parser implements stream which sequentially reads prolog terms from reader. By default PrologParser is abstract class but there is GenericPrologParser class provides minimalistic implementation.
+```
+Reader reader = new StringReader("hello(world). some({1,2,3}). power(X,Y,Z) :- Z is X ** Y.");
+PrologParser parser = new GenericPrologParser(reader, new DefaultParserContext(ParserContext.FLAG_CURLY_BRACKETS, Op.SWI));
+parser.forEach(System.out::println);
+```
