congrats on starting!
I did a similar thing, started out with running to the lenght of my fav song(after warm up) and then slowly increased the time.
I am now on 15mins - doesnt sound like a lot but i am immesly proud of myself.
i would run the same distance for a week then add an incline and after a week i would increase the time, next week increase incline again and so on.
I also think a rest day inbetween runs is a good idea (espssially for beginners - i tried every day but my body just gave up on the 5th day so i went to every 2nd day and i find it much easier and i dont get discouraged so easily)
