 ## Create documentation
 
-You can add, and edit the markdown files in `docs/` directory to update the documentation. There is a facility to check the status of your documentation by using:
+The document generation pipeline can generate both **html** and **pdf**
+versions of documentation.
+
+The generation of **pdf** version of documentation is controlled via
+a shell variable.

+```bash
+export MKDOCS_ENABLE_PDF_EXPORT=0 #disables generation of pdf document
+export MKDOCS_ENABLE_PDF_EXPORT=1 #enables generation of pdf document
