It's basically what the title says. It's a good guide for people who wanna learn to read and write Urdu (the Nastaliq script), through Hindi. Every section is well explained, along with examples and use cases of the letters. At the end of the book, there are a couple of very short stories and some shayaris written in the Nastaliq script for one to practice reading and understanding Urdu. It sets up a really good starting point into reading and writing the language.
