 ## What it is
 
 **Luma3DS** is a program to patch the system software of (New) Nintendo 3DS handheld consoles "on the fly", adding features (such as per-game language settings and debugging capabilities for developers) and removing restrictions enforced by Nintendo (such as the region lock).
-It also allows you to run unauthorized ("homebrew") content by removing signature checks.  
-To use it, you will need a console capable of running homebrew software on the ARM9 processor. We recommend [Plailect's guide](https://3ds.guide/) for details on how to get your system ready.

 Since Luma3DS v8.0, Luma3DS has its own in-game menu, triggerable by `L+Down+Select` (see the [release notes](https://github.com/AuroraWright/Luma3DS/releases/tag/v8.0)).

 To compile, you'll need [armips](https://github.com/Kingcom/armips) and a build of a recent commit of [makerom](https://github.com/profi200/Project_CTR) added to your PATH. You'll also need to install [firmtool](https://github.com/TuxSH/firmtool), its README contains installation instructions.
-For now, you'll also need to update your [libctru](https://github.com/smealum/ctrulib) install, building from the latest commit.
