There is a lot of information right here on this site that can help you. You just have to look for it.
While there is no way I can tell you even half of everything you need to know about breeding, I'll give you a few "heads up"
First off, you need to make sure you have the financial ability, the physical space, and the time to undertake this.
If you dont have enough money to do this right, and you go about it thinking "oh when I need the money I'll just save up for a bit or 'make it happen'", then you are going to have big problems! You need to factor in feeding, cleaning necessities, vet bills, any extra that you might see on your electric bill, new tanks and accessories, etc. Sometimes unexpected expenses come up and need to be taken care of immediately - you wont be able to wait till you've saved up enough or till your next paycheck, sometimes it has to be taken care of THAT DAY. So you really should have a few hundred you can dedicate to the breeding process.
If you dont have the physical space, you will end up having to sell your babies to any petshop that will take them (and that can be a really bad situation for a gecko). Or you'll end up with cage fights and wounded geckos from keeping them too close together for too long.
And if you dont have the time, you might forget about the incubating eggs and not catch a simple issue which result in losing the whole clutch. Or you'll forget to clean tanks, feed certain geckos, look for laid eggs, etc.
Please just dont get into this without thinking over every little detail first!
After you've thought all that through, then take a look at the geckos you intend to breed. Are they both at least 1 years old? Are the 100% healthy with no history of illness? Is the female in top health - has a great appetite, very active, doesnt fight, and has a very fat tail? (remember, overbreeding a female can cause her extreme stress which can lead to infertile eggs, heath problems in the female and her babies, as well as a very shortened lifespan). If you have enigmas you want to breed: have you checked their strains and such to be sure you should breed them? As enigmas already have issues, breeding certain ones together can cause them to have hatchling with extreme physical and mental deformities.
Im not trying to "scare" you out of it.. but its some serious stuff! Overall, you have to be very well informed and prepared before you start this.
I wish you well!
