-You can use `|widthxheight` to specify the image size at the end of image alt.
+When you set `size: true` in plugin options, you can use `|widthxheight` to specify the image size at the end of image alt.
 
 Both `width` and `height` should be number which means size in pixels, and both of them are optional (set `0` to indicate ignore).
 
-If you want the same behavior as Obsidian, you can pass `{ strict: true }` in plugin options. Now both `width` and `height` are both required to be set (one of them can be `0` to scale with radio according to the other).
