Hello and thanks for your interest in this project.
First, you should go to [url removed, login to view]
After having an idea of what it is, go to [url removed, login to view] and download the java source for the crawler.
Next, the output of this crawler should be reformatted (in the crawler itself) to match the template for new blocks in Blockly.
FYI, Blockly is a Scratch-like programming environment (mainly used for education), which produces code in various languages.
You can download the Blockly source code here: [url removed, login to view] and here is the custom block creation tutorial: [url removed, login to view]
Finally, the resulting source code of both the crawler and the augmented Blockly, should be returned to me, in order to put them on GitHub.
Let me know =)
