+<p>Piper makes integrating external tools into Burp easier.</p>
+<p> In true Unix
+fashion, small things that do one thing and do it well can be connected
+together like building blocks to aid quick experimentation. By lowering
+the level of coupling, any programming language can be used as long as
+it can accept inputs on the standard input or as command line
+parameters.</p>
+<p>Extending message editors for new formats or integrating a
+better comparator/diff tool is as simple as filling a short form with
+the command line and some details with sensible defaults.</p>
+<p>Useful configs
+can be shared using the the textual YAML format, the defaults already
+contain some simple examples.</p>
