A companion homebrew for Nintendo Switch that might prove useful if you are into https://github.com/XorTroll/uLaunch.

It can swap stock Home menu (qlaunch) with uLaunch and reboot to payload backing up everything useful you might have had in your “contents” folder in the process.
It can swap stock Home menu (qlaunch) with uLaunch and apply changes via rebooting to payload, backing up everything useful (e.g. a Home menu theme) you might have had in your relevant “contents” folders in the process.

## Installation and setup
Download uLaunch’s release, place /ulaunch from the release to the root of your SD card, create a folder named “ProtonELV” (without quotation marks, duh) inside /ulaunch. Place the contents of /atmosphere/contents (pun not intended; four folders) from the uLaunch’s release into /ulaunch/ProtonELV.
Download ProtonELV https://github.com/octopuserectus/ProtonELV/releases and delicately place it into /switch.
* Download uLaunch’s release https://github.com/XorTroll/uLaunch/releases archive, place /ulaunch from the archive to the root of your SD card, create a folder named “ProtonELV” (without quotation marks, duh) inside /ulaunch. Place the contents of /atmosphere/contents (pun not intended; four folders) from the uLaunch’s archive into /ulaunch/ProtonELV.
* Uninstall a custom Home menu theme if you have one and reboot. I found no way to swap folders which are MITM’ed without rebooting.
* Download ProtonELV.nro https://github.com/octopuserectus/ProtonELV/releases and delicately place it into /switch or wherever you want.
* Start humming “L’Internationale”.
* Run ProtonELV via Homebrew Menu (applet or title redirection mode, whatever rocks your spaceship).

## Controls
Controls are explained via on-screen prompts.

## Planned features
## Planned features (aka “would never implement those”)
Online install and update, install nigthly builds, not suck in general.
