3. Setting up a Blog Page

If you want to set up a blog page, you should use the “Blog page Template” that comes with the theme. To setup a blog page, follow these steps:

Step 1: First mark all the posts with a category called “blog” or something.
Step 2: Then create a new page and Give it a title. While in the post editor page, notice there is a box on right called “Page Attributes”. From this box, you can select multiple page templates. Select “Blog Page Template” from the dropdown list and save the page.
Step 3: Then Go to Appearance> hathor options> Misc. and select the category “blog” for “Display Blog Posts from a selected Category” option.
Step 4: Now view the created page, and you will see the page is displaying all the posts from your specified category.
