Congratulations on your new Bearded Dragon! Like previously mentioned, I wish it was more planned out though.
Not sure of the age, definitely a hatchling;
Hatchlings (up to 5 months of age) require mostly protein 80% protein to 20% greens, because they are growing that they do in the first months.
Juveniles (5-18 months of age require 50% protein to 50% greens. And adults (18 months and older) require 20% protein to 80% greens. So their requirements change as they age. Temperatures are also very important for proper digestion of their food. one side of the enclosure should be the hot side and the opposite side should be the cool side. You should provide a hide on each side, water should always be available even though they will get the majority of their water from their food. They should have a basking spot of a temperature of 105-110 degrees on the hot side, ambient temperatures of 85-95 degrees, and cool side between 75-85 degrees, nigh time temperature can go down to 75 degrees. The best way to measure the temperatures is with a digital thermometer with a probe, the probe can be placed anywhere you want to know the temp, it's always a good idea to know the basking temperature so by placing the probe of the thermometer directly on the basking spot will ensure that you know those temperatures you'll want them to be between 100-110 degrees. UVB is also very important, it provides vitamin D and is needed for the absorption of calcium.
Here is the sites caresheet, great information to always have at hand.

And here is the diet, remember that the staples are the most important part of the green part of the diet. I would print this off and keep it close at hand.
