Update index.html

Docker is the newest kid on the block regarding deployments. Previous meetups introduced the borough people to Docker itself.

However that's not all. Coupled with nodejs you can do pretty cool stuff, like launch multiple versions of your website at the same time in order to figure out when a visual bug was introduced.

I've been working on making that super simple with [spinup](https://github.com/thlorenz/spinup).
          
I will talk about that and other projects in addition to ideas that are now implementable to hopefully get more people on board with the docker/nodejs love affair. 

I'm open to speak in any slot.
