Roti/phulka or chapati whatever you like it is an Indian flatbread made with wholemeal wheat flour called "atta" in hindi. In India and Pakistan you use roti to scoop out bites of food instead of using utensils. Roti is the most general term used for this type of flat bread. I like to think of roti as the humblest of the flat breads. It does not require puffs like chapati or phulka, sure you can go for that puffs but it's also okay if the bread only puffs in spots. Also the roti does not require to be rolled out to a specific thickness, it will be okay if one is a bit thicker and the other thinner. The taste is always amazing.
Traditionally the dough for roti is prepared fresh by kneading (traditionally by hands) smooth, soft consistency dough similar to play dough. The prepared dough is then divided into equal parts and rolled into circular flat breads very much like tortillas. These dough circles are then cooked over a hot skillet and roasted over open flame until they puffed and cooked thoroughly. The wholewheat flour used to make roti is a whole grain flour with high gluten content. Just search for "atta" and you can find various brands on amazon. Also you may check your local Indian or ethnic grocery store for purchasing flour for roti as well. White wholewheat flour is an okay substitute for atta as well. You should never use all purpose flour or bread flour for making roti as the resultes roti will be stiff and crackly.
Here I am giving your a detailed step by step recipe of how to make roti in microwave while living in dorm room or away from your family on your own with minimal equipment. This is one of the easiest dorm room recipe, if you know how to knead the dough for roti then this microwave roti will be a child's play for you.
Place the flour in a bowl, add salt in it. Trickle in water a little at a time, until the dough comes together. (you may do this process in a stand mixer with a dough hook attached). 
Continue kneading the dough with the knuckles of your fingers, applying pressure.
Fold the dough using your palm and and knead again applying pressure with your knuckles. Knead it for at least 5 minutes until the dough is really smooth and supple. (you may add more water if i feels hard or tight or add more flour it feels too sticky while kneading).
Cover the bowl with a damp kitchen towel or or lid, let it rest for atleast 30 minutes.
Divide the dough in equal portions and make round balls, depending on the size of roti you want make large or small balls.
Dust some flour on the work surface and roll the roti with the rolling pin, roll into even and fairly thin round (about 2 to 3 millimeters thick).
Put the chapati directly over the clean microwave plate or any other microwave safe plate.
Cook for almost 30 seconds, then flip the side and cook for another 30 seconds.
