     - The CSV file itself contains the Titles and File names of the tutorials in the order in which they should be read.
 
 - ### `export_tutorials.py`
+
   - This script reads the list of notebooks from `/utils/tutorials/notebooks.txt` and parses the HTML files (downloaded temporarily to `/utils/tutorials/html-notebooks`) using `BeautifulSoup`.
   - The script then creates a react component for each tutorial and exports it to the `/deepchem/pages/tutorials` directory.
   - The script also creates a json data file for each tutorial and exports it to the `/deepchem/data/tutorials` directory.
   - The template for the react components is stored in `utils/tutorials/tutorial_component_template.py`.
     Please note, that any files required by scripts are generated by the scripts themselves and are not stored in the repository.
 
+- ### `build_pdf_book.py`
 
+  - The script reads the list of notebooks from `utils/tutorials/website-render-order` and converts the HTML files (downloaded temporarily to `/utils/tutorials/html-notebooks`) to PDF files using `pdfkit` and stores them in `/utils/tutorials/storage/`.
+  - The script then merged these PDFs and creates the file `merged.pdf`.
+    - Please note, pdfunite package is required to be installed for merging. `apt install poppler-utils`

+This script is used to build the pdf book from DeepChem Tutorials.
+
+Requirements:
+    - pdfunite
+    - pdfkit
+
+Example Usage:
+    - Run the script "fetch_tutorials.py" // It will fetch all the tutorials.
+    - Run the script "build_pdf_book.py"
+    - It may cause error, mostly due to the type of graphic used in some tutorials
+    which donot compile properly, remove them from the website-render-order or fix
+    them, and run this script again.
+
+NOTE:
+    - NO FILES OR DIRECTORIES HAVE TO BE CREATED MANUALLY. The script will create the required directories and files.
+    - Run scripts in the Top-Level folder.
