At last, I found a book that addresses the issues beginners in this field usually face. I started this book for a project on molecular dynamics but that didn't help. However, for density functional theory, chapter 4 to chapter 6 are extremely helpful. Not only it gives away the basic concepts without involving all the intricacies but also it gives a hands-on approach to DFT in chapter 7 using Quantum ESPRESSO. There is another book on QE that has been published in 2023. Other than that this book is the best resource as a starting point to learn DFT. However, chapter 7 to chapter 9 is not recommended not because they are poorly written, but because DFT is meant to be learned by doing. So a youtube tutorial is much helpful in this case. And in some places, the book's instruction is not compatible with the updated version of QE.
