 # Luma3DS
 *Noob-proof (N)3DS "Custom Firmware"*
 
-**Compiling:**
+## What it is
 
-First you need to clone the repository recursively with: `git clone --recursive https://github.com/AuroraWright/Luma3DS.git`
-To compile, you'll need [armips](https://github.com/Kingcom/armips), [bin2c](https://sourceforge.net/projects/bin2c/), and a recent build of [makerom](https://github.com/profi200/Project_CTR) added to your PATH.  
+**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)).
+
+---
+
+## Compiling
+
+First you need to clone the repository with: `git clone https://github.com/AuroraWright/Luma3DS.git`  
+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.  
 For your convenience, here are [Windows](http://www91.zippyshare.com/v/ePGpjk9r/file.html) and [Linux](https://mega.nz/#!uQ1T1IAD!Q91O0e12LXKiaXh_YjXD3D5m8_W3FuMI-hEa6KVMRDQ) builds of armips (thanks to who compiled them!).  
 Finally just run `make` and everything should work!  
-You can find the compiled files in the 'out' folder.
