-# Luma3DS
-*Noob-proof (N)3DS "Custom Firmware"*
+# Luma3DS-3GX Plugin Edition
+*Noob-proof (N)3DS "Custom Firmware", with 3GX plugins support*
 
-## What it is
+### 3GX Plugin Edition
+This edition of **Luma3DS** allows the loading of **.3GX plugins** in Luma3DS, which are otherwise officially unsupported.
 
-**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)).
+#
+### How to install this Edition
+1. download the latest `boot.firm` from [the releases page](https://github.com/mind-overflow/Luma3DS-3GX/releases/latest)
+2. put the downloaded `boot.firm` file in the `root` directory of your SD card (`sd:/boot.firm`), overwriting the official Luma3DS `boot.firm`.
+3. (re)boot your 3DS, and when prompted, enable:
+    - "Enable game patching"
+    - "Show NAND or user string in System Settings"
+4. press `START` and let your 3DS boot.
 
----
+You successfully installed the 3GX Plugin Loader! Now, proceed to the next step to learn how to install and enable 3GX plugins.
 
-## Compiling
+#
+### How to install 3GX plugins
+Plugins have to be installed in the `sd:/luma/plugins` folder.
+Usually, you need to put your specific plugin in the `<TITLEID>` subdirectory, eg: `sd:/luma/plugins/<TITLEID>/<filename>.3gx`.
+However, a `default.3gx` plugin can also be placed in the main `sd:/luma/plugins` directory: `sd:/luma/plugins/default.3gx`.
 
-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.
-You'll also need to update your [libctru](https://github.com/smealum/ctrulib) install, building from the latest commit.  
-Here are [Windows](https://buildbot.orphis.net/armips/) and [Linux](https://mega.nz/#!uQ1T1IAD!Q91O0e12LXKiaXh_YjXD3D5m8_W3FuMI-hEa6KVMRDQ) builds of armips (thanks to who compiled them!) and [makerom](https://github.com/Steveice10/buildtools/tree/master/3ds) (thanks @Steveice10!).   
-Run `make` and everything should work!  
-You can find the compiled files in the `out` folder.
+So:
+``` yaml
+    sd:/luma/plugins/default.3gx # will be loaded for all games, low priority
+    sd:/luma/plugins/<TITLEID>/<filename>.3gx # will only be loaded for the specified title, high priority
+```
 
----
+Now you know how to install 3GX plugins! Proceed to the next step to learn how how to enable 3GX plugins.
 
-## Setup / Usage / Features
+#
+### How to enable 3GX plugins
+1. when booted, press `L + D-Pad Down + Select` to open the Rosalina menu.
+2. Press `D-Pad Down` again until `Plugin Loader`, is selected, then press `A` and set it to `[Enabled]`.
 
-See https://github.com/AuroraWright/Luma3DS/wiki
+Done! You learned to install the 3GX Plugin loader, install 3GX Plugins and enable them. Now, simply launch the game you want to play and press `SELECT` to open up the 3GX menu!
