I now to use time capsule as my hardrive, delete everything from my macbook and run my Apple TV + iPhones + mac book off the data in the time capsule hard drive? how do I access time capsule from thre other devices

i have recently purchsed timecapsule. My other apple products are iphones 4 and 5 , appletv, macbook. I had no storage space on my mac book and couldnt back up my iphone so I bought timecapsule hoping it could function like my hardrive, freeing up space on my other devices and sending data wirelessly to them all.

I have backed up on time capsule and time machine. BUt I cant work out how to access the time capsule from my other devices.

I want my itunes library in my time capsule, not on my macbook, and I want movie downloads etc... available to apple tv...

Any help would be gret. thank you
