 MCPE Linux Launcher
 ===================
 
-## Required packages
+A fork of [mcpelauncher-linux](https://github.com/MCMrARM/mcpelauncher-linux) (commit from 2017, MCPE 1.1) with additional features and improvements
 
-```
+## Features
-    sudo apt-get install cmake zlib1g-dev:i386 libncurses5-dev:i386 libgles2-mesa-dev gcc-multilib g++-multilib zlib1g-dev:i386 libx11-dev:i386 linux-libc-dev:i386 uuid-dev:i386 libpng-dev:i386 libx11-dev:i386 libxext6:i386
+- Dedicated server support
+- Compatibility fixes for building with the latest GCC
+- Other quality-of-life improvements
+
+## Required Packages
+
+### Ubuntu / Debian
+Install the necessary dependencies with:
+
+```bash
+sudo dpkg --add-architecture i386
+sudo apt-get update
+sudo apt-get install cmake zlib1g-dev:i386 libncurses5-dev:i386 \
+libgles2-mesa-dev libegl1-mesa-dev:i386 gcc-multilib g++-multilib \
+libx11-dev:i386 linux-libc-dev:i386 uuid-dev:i386 libpng-dev:i386 \
+libxext6:i386
 ```
 
-If g++-4.9 fails to install and you're using Ubuntu 14.04 you may need to add the repository ppa:ubuntu-toolchain-r/test.
+### Arch Linux
+Install the necessary dependencies with:
 
-You'll also need to install 32-bit version of the graphic drivers (nvidia drivers ask you about that at installation, so
+```bash
-you may need to reinstall/reconfigure them; if you use mesa you'll need to install the libgles2-mesa-dev:i386 and
+sudo pacman -Syu base-devel cmake zlib libpng libx11 libxext libglvnd \
-libegl1-mesa-dev:i386 packages)
+libxrandr libxi mesa lib32-gcc-libs lib32-glibc lib32-mesa lib32-libx11 \
+lib32-libxext lib32-libxrandr lib32-libxi
+```
 
-You may also need to do `sudo dpkg --add-architecture i386` if you have never installed i386 packages before.
+Make sure the multilib repo is enabled in `/etc/pacman.conf`.
 
 ## Compiling
 This app uses cmake so it is enough to do:
 
 ```
-    cmake .
+mkdir build
+cmake ..
 make
 ```
 
 ## Running
 1. Clone this repository
 2. Compile the launcher
-3. You'll need to obtain a x86 MCPE .apk. The easiest way to do so is to use the
+3. Obtain a x86 MCPE 1.1 apk file
-[Google Play downloader tool](https://github.com/MCMrARM/Google-Play-API) (it is an console app; remember that
-you need to type 'y' when you are asked if you want to use x86 as the architecture, and you must have purchased MCPE
-on the Google account you are logging in with; the package name of MCPE is `com.mojang.minecraftpe`)
 4. After you have downloaded MCPE, place it in the directory where you'll be running this app, and run ./extract.sh _filename_
 5. Run the launcher!
 
 If the extract script fails with an error about the .apk not being x86, it means that you have provided it a bad .apk.
-You'll need to purchase MCPE on Google Play and use the downloader tool.
+
+## Using the Dedicated Server
+1. Create a server.properties file and fill in your settings. An example is located in the root of this repository.
+2. Run the server binary that you built earlier
