+Cross-compiling on Linux to Web Assembler vis Emscripten
+--------------------------------------------------------
+
+Install Emscripten cross-compilers (e.g. `sudo apt install emscripten`) on a modern linux distro.
+
+Then run `emcmake cmake .. -DVIDEORECORDER=OFF -DVULKAN=OFF -DSERVER=OFF -DTOOLS=OFF -DPREFER_BUNDLED_LIBS=ON` in your build directory.
+
+To test the compiled code locally, just use `emrun --browser firefox DDNet.html`
+
+To host the compiled .html file copy all `.data`, `.html`, `.js`, `.wasm` files to the web server. (see /other/emscripten/minimal.html for a minimal html example)
+
+Then enable cross origin policies. Example for apache2 on debian based distros:
+```bash
+sudo a2enmod header
+
+# edit the apache2 config to allow .htaccess files
+sudo nano /etc/apache2/apache2.conf
+
+# set AllowOverride to All for your directory
+# then create a .htaccess file on the web server (where the .html is)
+# and add these lines
+Header add Cross-Origin-Embedder-Policy "require-corp"
+Header add Cross-Origin-Opener-Policy "same-origin"
+
+# now restart apache2
+sudo service apache2 restart
+```

 How to build the ddnet-libs for Android:
 ========================================
 -	There is a script to automatically download and build all repositories, this requires an active internet connection:
-	`scripts/android/gen_android_libs.sh <directory to build in>`
+	`scripts/compile_libs/gen_libs.sh <directory to build in> android`
 	Warning!: DO NOT CHOOSE A DIRECTORY INSIDE THE SOURCE TREE
 	
 	After the script finished executing it should have created a ddnet-libs directory which created all libs in the right directory format and can be merged with ddnet-libs in the source directory
