+## Installation
+
+### Easy mode
+
+I highly recommend the updater tools by [@mattpannella](https://github.com/mattpannella) and [@RetroDriven](https://github.com/RetroDriven). If you're running Windows, use [the RetroDriven GUI](https://github.com/RetroDriven/Pocket_Updater), or if you prefer the CLI, use [the mattpannella tool](https://github.com/mattpannella/pocket_core_autoupdate_net). Either of these will allow you to automatically download and install openFPGA cores onto your Analogue Pocket. Go donate to them if you can
+
+### Manual mode
+To install the core, copy the `Assets`, `Cores`, and `Platform` folders over to the root of your SD card. Please note that Finder on macOS automatically _replaces_ folders, rather than merging them like Windows does, so you have to manually merge the folders.

 ## Usage
 
 ROMs should be placed in `/Assets/nes/common`
