-    This configuration file was written by the eclipse-cs plugin configuration editor
+
+  Checkstyle configuration that checks the sun coding conventions from:
+
+  - the Java Language Specification at
+  http://java.sun.com/docs/books/jls/second_edition/html/index.html
+
+  - the Sun Code Conventions at http://java.sun.com/docs/codeconv/
+
+  - the Javadoc guidelines at
+  http://java.sun.com/j2se/javadoc/writingdoccomments/index.html
+
+  - the JDK Api documentation http://java.sun.com/j2se/docs/api/index.html
+
+  - some best practices
+
+  Checkstyle is very configurable. Be sure to read the documentation at
+  http://checkstyle.sf.net (or in your downloaded distribution).
+
+  Most Checks are configurable, be sure to consult the documentation.
+
+  To completely disable a check, just comment it out or delete it from the file.
+
+  Finally, it is worth reading the documentation.
