A few mistakes in the readme.md text

[ahmad-PH]

1. Under Who we are, at the end of the 2nd paragraph it is written:
   "He is the co-founder, along with Dr. Rachel Thomas, of fast.ai, the organization that built the course this course is based on."
   Was this intentional? It feels like a mistake to me.

2. Under Who we are, at the last paragraph:
   " We always teaching through examples."
