 # ProtonELV
-(with an emphasis on *expendable*)
+(aka “Proton expendable launch vehicle” with an emphasis on *expendable*)
 
-A companion homebrew for https://github.com/XorTroll/uLaunch
+A companion homebrew for Nintendo Switch that might prove useful if you are into https://github.com/XorTroll/uLaunch.
 
-At the moment it can swap 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 reboot to payload backing up everything useful you might have had in your “contents” folder in the process. 
 
-Planned features: online install, nigthly builds. 
+## 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.
 
-It began as a mod for https://github.com/Atmosphere-NX/Atmosphere/tree/master/troposphere/reboot_to_payload I wrote while learning C.
+## Controls
+Controls are explained via on-screen prompts. 
+
+## Planned features
+Online installation and update, install nigthly builds, not suck in general. 
+
+## Credits
+Let’s be honest, it’s just a few extra lines of code inside https://github.com/Atmosphere-NX/Atmosphere/tree/master/troposphere/reboot_to_payload.
