 Instructions/files for building a custom LEDE image to turn cheap routers into a Nintendo Switch "modchip"/"dongle"
+
+These instructions target the "A5-V11" devices, although you should be able to make this work on any router with USB host support.
+
+These instructions do not cover the actual installation to the device, see https://openwrt.org/toh/unbranded/a5-v11
+
+# Usage
+
+Once installed, just plug in your switch in RCM mode, and the payload will get launched automagically!
+
+To set a custom payload, replace `/usr/share/fusee-nano/payload.bin`. (`fusee.bin` is bundled as a default payload, from https://github.com/ktemkin/Atmosphere/tree/poc_nvidia/fusee)
+
+# Compiling From Source
+
+1. Clone this repo, and the main LEDE repo
+
+```sh
+git clone https://github.com/DavidBuchanan314/fusee-lede/
+git clone -b lede-17.01 https://git.lede-project.org/source.git lede
+```
+
+2. Copy over the `fusee-nano` package, and the EHCI patch
+
+```sh
+cp -r fusee-lede/fusee-nano lede/package/utils/
+cp fusee-lede/899-ehci_enable_large_ctl_xfers.patch lede/target/linux/generic/patches-4.4/
+```
+
+3. Update LEDE feeds and configure
+
+```
+cd lede
+./scripts/feeds update -a
+./scripts/feeds install -a
+
+make menuconfig
+```
+
+If you run into issues here, refer to https://wiki.openwrt.org/doc/howto/build
+
+When in the configuration menu, you will need to set the following options:
+
+```
+Target System            => MediaTek Ralink MIPS
+Subtarget                => RT3x5x/RT5350 based boards
+Target Profile           => A5-V11
+Utilities > fusee-nano   => <M>
+```
+
+4. Compile!
+
+```
+make -j12
+```
+If all goes well, you should find files ready to flash here:
+
+```
+bin/targets/ramips/rt305x/lede-ramips-rt305x-a5-v11-squashfs-factory.bin
+bin/targets/ramips/rt305x/lede-ramips-rt305x-a5-v11-squashfs-sysupgrade.bin
+```
