+# Using the Firmware Updater
+Go to the website for the [Firmware Updater](https://oscr.tools/update) and follow the prompts. You must be running a Chromium-based browser (Chrome, Edge, etc) on a desktop (or laptop) to use the Firmware Updater -- it does not work on mobile browsers or Firefox.
+
+Before updating ensure all cartridges are removed from the OSCR. If you don't see your OSCR in the list you must install the driver first. There's a link to the driver installer on the updater page. Download and extract the installer then run it. Follow the instructions, restarting if needed. Your OSCR should show up then.
+
+Currently, the Firmware Updater cannot be used to flash a new Arduino for the first time or to update very old OSCR firmware versions. Use the manual method described below for that.

+# Updating Manually

 The Cart Reader's firmware is released as source code and needs to be compiled before flashing. Both compiling and flashing can be done with the **Arduino IDE**.     
 You can either use the [Portable Release](https://github.com/sanni/cartreader/wiki/How-to-flash-the-Arduino#portable-release) or the [official Arduino IDE installer](https://github.com/sanni/cartreader/wiki/How-to-flash-the-Arduino#official-arduino-ide-installer).

 Each Cart Reader release comes with a pre-configured and tested portable Arduino IDE tailored for that specific release which includes the Cart_Reader.ino sketch as well as all the needed Arduino libraries and SD database files and does not interfere with any previous Arduino installation.    
 
 ### To upload the firmware to the Cart Reader please follow these steps:
