If you don't have digital thermometers inside of your cage or a temperature checking thermal gun (something like this https://www.amazon.com/ANGGO-Non-contact-Temperature-Thermometer-Precisely/dp/B01FYVEJMY/ref=zg_bs_9931459011_6/139-0586439-0036854?_encoding=UTF8&psc=1&refRID=92JFJMYZYZGMZY071HNT), do yourself a favor and get one. It takes the guesswork and anxiety out of making sure they have a good temperature gradient. If you go with digital thermometers inside the cage, you need one that can read two different temperatures (can't find the exact one I used previously, but it was something like this https://www.acurite.com/indoor-outdoor-thermometer-with-probe.html) or two within the cage (they do make extremely small ones). You should also get a humidity gauge, again digital is better. Currently I use one humidity gauge in the center of each enclosure and a thermometer gun.

Do not use the little plastic thermometers/humidity gauges that stick to the side of the glass, aside from them being less accurate they can come off and stick to your snake, which is no good.

Check for any weak points in your enclosure often. If there is mesh, make sure there are no holes or stretched spots, they are escape artists and even if they don't escape, can hurt themselves in the attempt. Lids should be secured at all times you don't have eyes on the cage.

Feeding inside or outside of the cage is a hot button issue and I won't recommend one way or another, but I will say if you feed in cage, be careful about bedding ingestion, it can cause impaction (bowels becoming obstructed with indigestible material). If you feel your snake is ingesting bedding when you feed, try making sure the food item is completely dry when you put it in and also laying down something to feed on, like flat rocks (what I personally use), a paper plate, regular plate, or newspaper. Avoid paper towels, if blood gets on it, snake could ingest that too.

Make sure to clean any new cage decor, I use regular soap and water and rinse VERY well for everything that isn't porous. That can get a little tricky, but google "How to clean *insert the thing you are trying to clean*".

Clean water regularly. Regular handling (multiple short sessions is better than longer sessions) is the key to taming them down if they are a little wild (which really depends on age and previous home handling, younger snakes tend to be more nippy than adults). Give the snake a decent amount of time to acclimate to the enclosure before you start working on getting them used to you by handling, most I have heard say a week. Don't handle for around 24 hours after feeding.

Oh, and enjoy your new buddy!

That is about all I can think of at the moment, feel free to ask specific questions if you have them. :)
