@@ -4,11 +4,17 @@ WordPress plugin that adds shortcodes for current, published, and last modified
 ## Purpose
 The main purpose of this plugin is to dynamically add dates to post titles. The shortcodes also work in meta descriptions (Rank Math, Yoast, SEOPress) and post content.
 
+You can use the `adjust` parameter for `[currentday]` to display the date for tomorrow, yesterday, the day after tomorrow, etc. This can be useful to make discounts always expire "tomorrow", for example: "Hurry up! This discount expires on `[currentmonth] [currentday adjust="+1"]`!"
+
 ## Available Shortcodes
+- **[currentday]** - current day
+- **[currentday adjust="+1"]** - tomorrow (both `+` and `-` are supported)
 - **[currentmonth]** - current month
 - **[currentyear]** - current year
+- **[publishedday]** - day the post/page was published
 - **[publishedmonth]** - month the post/page was published
 - **[publishedyear]** - year the post/page was published
+- **[modifiedday]** - day the post/page was last modified
 - **[modifiedmonth]** - month the post/page was last modified
 - **[modifiedyear]** - year the post/page was last modified
