Any pictures on installing sliding doors

[johnson1975]

I am going to tackle the installation of my sliding doors on my shop - I have already purchased all the hardware. I plan to have the bottom rail and have the cannon ball style rollers for top ( I was told there were better quality). I am comfortable constructing the actual doors - just not real sure how the hardware is mounted etc..

I am not sure if I need to try and hang the top of thedoor 1st and then install bottom rail or ??

Any pics or tips would be great

The doors will be 12x6 each
