 **How to Run Script :**
 
 - Once you execute the script. It will generate all certificates and keys in a subfolder named by current datetime.
 - **Notes**: While execution of "gen_all_certs.sh" script on **Unix/Linux Operating System,** Please provide script argument "DN_template.cnf" file which consists of country related information to generate all required certificates (TLS,SCA,UP)
 
-
-
-	```
-	**For Mac/Linux/Unix**
-	cd scripts/certgen
-	./gen_all_certs.sh DN_template.cnf	   
- 	zsh ./gen_all_certs.sh DN_template.cnf      ## If you are using Ubuntu OS
+```
+**For Mac/Linux/Unix**
+cd scripts/certgen
+./gen_all_certs.sh DN_template.cnf	    ## Provide DN_template.cnf file as a script argument.
+zsh ./gen_all_certs.sh DN_template.cnf      ## Use this if you are using Zsh on your Ubuntu system.
         
-	**For Windows:**
-	cd scripts/certgen
-	./gen_all_certs.ps1
-	```
+**For Windows:**
+cd scripts/certgen
+./gen_all_certs.ps1

 This setup generates all required certificates (TLS, SCA, UP) and keys in a timestamped subfolder, based on the configuration specified in DN_template.cnf for Unix/Linux and the environment variables set in the current PowerShell session for Windows.
