This option involves less code, and automatically generates Older Post / Newer Post links which will be translated to the language chosen in your blog's settings. For this option you'll only need to add one line of code. Again, it's right after the [/blogger] and before the [/div][/div][/div] tags:
From here you just need to save your changes, and then you are finished.
