Hello . I;m buying a Miracle Truss building that was never put up. It has detailed directions for erecting it and nothing on the slab and footers. Any info would be helpful

Slab and footing(s) would be dictated by geographic region and/or local convening authority (building dept).
Check with your convening authority about permit requirements and common checklist for inspections.

What the heck is a "convening authority?" I've only lived in cities and they all have "building departments." (Or similar.)

Think he meant "governing authority" but spell checkers sometimes fix slight misspellings with things you don't want to say.

Some of the guys from Miracle Truss went to Bison Buildings. If you need technical help I would think if you ask nicely of them you might get it.
The pre-engineered building manufacturer's I have dealt with almost never give out foundation recommendations. Too many local code variables, soil conditions, and additional liability.
What they will give you is "reaction loads" for each column that will indicate the horizontal and lateral forces. You or your foundation designer/structural engineer can then apply these loads to your footing design.

Miracle truss makes a nice building for the money, I have erected many of them. We normally place them on a frost protected slab (Alaskan slab). Do a search for "Frost protected slab" and you should come up with good details. PM me for more specifics if needed.

I helped put a single miracle truss building up twice. Helped tear it down once to move it. Pretty straight forward design that is pretty easy to assemble with just two guys and some scaffolding. If you get the assembly instructions you should be set. Check the metal for the roof and walls. The one I did sat for a while with the metal stacked and it had a ton of rust pin holes in it.
A slab is not needed until after the building is put up. We boxed out a form for the footers and went several feet into the ground. the measurement for the footer bolt spacing when measured from opposing walls is critical. We did the first building a little too close and could not het the truss plates to bolt to the wall plates properly. From what I remember also really look at the spacing on the footer bolts four corners. They are slightly different the spacing on the walls. The first time we put it up the bolts wound up way off on the corners for this reason. The second time we got it right.

I thought this was going to be about some info ad stuff like you see in Readers Digest for hernias.

I built a Kentucky Steel building which is very similar to Miracle Truss but was about half the price. They specified 20" (round or square) concrete piers under each post. IIRC the piers were 3'-4' deep. I could have used cardboard sonotube but I made my own forms for square piers. I poured my slab around the piers a few years after I built it.

When we did mine, we put 30"x30"x30" footers for the center trusses and 12" round holes 30" deep for the end wall beams for the one end and a frost wall for my living area for the other end. We also poured the floor after it was erected to use the bottom frame board as the outside form for the concrete.

I thought when I first saw this miracle truss that it was for a medical appliance for hernia's I thought I had seen one on TV a few years ago.

OK because I was wondering if the military was going to be involved.
Yes, the most common use of "convening authority" is a part of the military/UCMJ. It's a term I've used for many years because it was legal jargon in a contract I used. Think of it this way- ICC (International Code Council) to include engineers and professionals in their respective fields that deal with construction, State governments, County governments, city governments. All can have authority over the building process as if convened. I guess if I used "governing authority" it would simplify things- if I could get out of the habit.

My MT building sat under tarps for 2 years before I started to assemble it. Minor surface rust here and there on a few of the truss's, no big deal. The panels sat for 3 years, stored the way MT said not to... no issues with them. Good luck, my biggest concern for you would be that you get everything!!
