Mediumish theme

[censusoptimus]

Hi, I'm very happy with bludit. I'm trying to modify mediumish theme for my blog https://censusoptimus.lt/ but need some help. How can I add items to "All stories" block in the homepage?

1) Go in the Administration panel to "Settings" > "General" > "Advanced".
2) Select at "Items per page" the number of items you want to show per page.
3) Select at "Order content by" the option "Date".

This are the default settings to show posts on the mainpage.
