 ## 1.0 Requirements
 The following tools or applications are required to develop the web client:
 - [1.1 IDE](#11-ide)
-- [1.2 PHP](#12-php)
-- [1.3 NodeJS](#13-nodejs)
-- [1.3.2 NPM](#132-npm)
-- [1.4 Git bash](#14-git-bash)
+- [1.2 NodeJS](#12-nodejs)
+- [1.2.2 NPM](#122-npm)
+- [1.3 Git bash](#13-git-bash)
+- [1.4 Docker](#14-docker)
 
 ### 1.1 IDE
 It does not matter which IDE you use,  
 you could even use a command line text editor for developing.
 
-### 1.2 PHP
-For having a test environment you require an installation of PHP 5 or grater.  
-You could just download PHP from [here](https://windows.php.net/download#php-7.4).  
-Note:  
-`php.exe` must be accessible via the command line.  
-This means you'll have to add the `bin` folder to your `PATH` variable.  
-
-### 1.3 NodeJS  
+### 1.2 NodeJS  
 For building and serving you require `nodejs` grater than 8.  
 Nodejs is easily downloadable from [here]().  
 Ensure you've added `node.exe` to the environment path!  
 
-### 1.3.2 NPM 
+### 1.2.2 NPM 
 Normally NPM already comes with the NodeJS installer.  
 So you don't really have to worry about it.  
 NPM min 6.X is required to develop this project.  
 With NPM you could easily download all required dependencies by just typing `npm install`.  
 IMPORTANT: NPM must be available within the PATH environment variable!  
 
-### 1.4 Git bash
+### 1.3 Git bash
 For using the `.sh` build scripts you require Git Bash.  
 A minimum of 4.2 is recommend, but in general every modern version should work.  
 
+### 1.4 Docker
+For building the native scripts you need docker.  
+Just install docker from [docker.com](https://docs.docker.com).  
+Attention: If you're having Windows make sure you're running linux containers!  
+  
+In order to setup the later required containers, just execute these commands:  
+Make sure you're within the web source directory! If not replace the `$(pwd)` the the path the web client is located at  
+```shell script
+docker run -dit --name emscripten -v "$(pwd)":"/src/" trzeci/emscripten:sdk-incoming-64bit bash
+```

 ### 2.2 Setting up native scripts  
 TeaWeb uses the Opus audio codec. Because almost no browser supports it out of the box  
 we've to implement our own de/encoder. For this we're using `emscripten` to compile the codec.  
-Because this is a quite time consuming task we already offer prebuild javascript and wasm files.
-So we just need to download them. Just execute the `download_compiled_files.sh` shell script within the `asm` folder.
