-Apache NetBeans is an effort undergoing incubation at The Apache Software
-Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of
-all newly accepted projects until a further review indicates that the
-infrastructure, communications, and decision making process have stabilized in
-a manner consistent with other successful ASF projects. While incubation
-status is not necessarily a reflection of the completeness or stability of the
-code, it does indicate that the project has yet to be fully endorsed by the
-ASF.

 $ jackpot --help
 ```
+
+### Example
+
+Consider this sample code:
+
+```
+package test;
+
+public class Test {
+    public void test(boolean b) {
+        int i = 0;
+        if (b)
+            System.err.println("was true");
+            assert (i = 1) == 1;
+    }
+}
+```
+
+It is possible to get a warning for the improper indentation like this:
+```
+$ jackpot --hint "Confusing indentation" <somedir>/src
+<somedir>/src/test/Test.java:9: warning: [Confusing_indentation] Confusing indentation
+            assert (i = 1) == 1;
+            ^
+```
+
+Or a warning for the side-effects inside the assert:
+```
+$ jackpot --hint "Assert with side effects" <somedir>/src
+<somedir>/src/test/Test.java:9: warning: [Assert_with_side_effects] Assert condition produces side effects
+            assert (i = 1) == 1;
+                    ^
+```
+
+All supported hints can be listed using:
+```
+$ jackpot --list
+```
+
+It is also possible to use a configuration file which enables multiple hints at once using:
+```
+$ jackpot --config-file <path-to-config-file> <path-to-sources-to-check>
+```
+
+The config file can be generated by the NetBeans IDE, using Project Properties/Hints, or similar ways.
