Not sure if this is the correct place to ask this but here goes nothing.

I setup openelec's Kodi on a Raspberry pi2. I uploaded a video and managed to get it to play on a connected TV via HDMI. What I can't seem to figure out is how to have Kodi serve as a media server so I can browse media using my phone's or computer's browser and play it. I've been through the settings available, installed several addons(i.e chorus etc) and I still can't see how to make this happen. Whenever I open a video on my browser after logging into the Kodi web interface, it still plays it on the TV connected to the PI.

Almost all Google results out there talk about casting from device onto TV and chromecast. I want to be able to play this media on my local browser. And no, I can't use the Kodi app because I'm using an un-supported Phone and computer OS.
