+
+yuzu has a powerful resolution rescaler allowing for the upscaling of the game's docked and undocked render resolution.
+
+### Accessing the feature
+
+The options for the resolution rescaler can be accessed via the yuzu Configuration menu `(Emulation > Configure...)`, 
+in the `Graphics` tab, under `Internal Resolution`:
+
+{{< imgs
+   "./scanner.png"
+>}}
+
+Clicking on the `Internal Resolution` dropdown list displays options for the upscaling factor, alongside its respective 
+resolution that it will output for `(Undocked/Docked)`:
+
+{{< imgs
+   "./scanner+dropdown.png"
+>}}
+
+### Profile Scanner
+
+Selecting the `Profile Scanner (Native)` option allows yuzu to continuously analyse the game's rendering methods in order 
+to create its respective resolution rescaling profile. After the creation of the rescaling profile, the upscaling factor 
+of choice can then be selected from the `Internal Resolution` dropdown list.
+
+**NOTE:** For optimal results, it is recommended to completely traverse throughout all of the game while having the Profile 
+Scanner enabled to complete the analysis of the game's rendering methods.
+
+### Resolution rescaling profiles
+
+Resolution rescaling profiles can be found under `%APPDATA%/yuzu/rescaling` on Windows and `~/.local/share/yuzu-emu/rescaling/` 
+on Linux, or you can right-click the game on the UI and click on `Open Rescaling Profile`. Rescaling profiles are transferable 
+for use in other computers.
