Yes, there are things on the internet to help with a set up like mine. 
 
Each plant requires two 5 gallon buckets plus one bucket for a water reservoir.  Only the water reservoir and the end of the line plant have one 1/2" rubber grommet for the 1/2" pex piping.  I drill out a centered 2 1/2" hole in the bottom of the plant bucket, this is where a 3" slotted mesh net plant pot is placed.  A wick of an old rag is made, knotted at one end and passed up through the bottom of the plant pot to about half way up the bucket.  I also drill a number of 1/4" holes in the bottom of the plant bucket.  The purpose is to get the plant's roots to grow down to the water source.  
 
The water source bucket have 3/4" holes 180 degrees from each other 1 1/2" on center up from the bottom.  The rubber grommets should fit tightly in the side(s) of the bucket.  The  1/2" pex pipe will also be a tight fit into the grommets.  I use a dab a Jack's lube commonly used on pool filters to facilitate the pex pipe.  
 
The soil mix can be your own or a commercially prepared medium.  I prefer a mix of sphagnum moss, garden soil, composted manure, perlite or vermiculite and fertilizer.  When you fill the plant bucket make sure the wick is centered as you add your soil mix. 
 
Once your plants are set put a layer of mulch over the top of the soil.  You can also cover the top of the bucket with plastic to make sure the plant's roots grow down instead of seeking surface water. 
 
Make sure the system is level so the water travels from the reservoir to all buckets on the line.  If you want drill a weep hole up about 3" in the last bucket so you know the system is working properly.  Check your water reservoir daily as the five gallon bucket may need to be filled a number of times. 
 
I have used this system since 2016 and have grown tomatoes, peppers, zucchini, summer squash, cucumbers, eggplant, green beans, lettuce, basil and parsley.   I use one bucket for each tomato plant but put three/four pepper or eggplant in the same bucket.   
 
This system economizes water usage, eliminates weeds and waste of fertilizer. 
 
I recommend the use of wooden stakes and tomato cages because the plants will get heavy.  Stake the pepper plants too (I use bamboo). 
 
The rubber grommets, slotted mesh pots can be purchased on Amazon.  Pex pipe and buckets at your local hardware or big box store.
 
Good luck.
