[ayushman...@gmail.com]

Hello mentor and developers 

I am Ayushman Koul, a student at GCET, Jammu. I went through the Portia GSoC 2018 ideas page and found the project: "Increase Crawling Performance through page clustering" very interesting.

Also, I encountered one bug raised by GitHub user https://github.com/scrapinghub/portia/issues/840.This bug seems interesting to me and want to work on fixing this.Please guide me how can I fix this bug.

Also, I want to contribute Portia community as a part of GSOC 2018.

I will be extremely thankful if someone could guide me regarding the same.

Regards

Ayushman Koul
