-This project is a port of VLC to run completely in the webbrowser.
+This project is a port of VLC to run completely in the web-browser.
 
 It is, of course, quite insane, but it will be doable in the future, as WASM improves.
 
-Notably when we have:
+It started with an asm.js port, now that WASM is ready with :
  - threads
  - WASM (and not only asm.js)
  - SIMD.js/wasm
  - Full webgl support
  - Audio support in threads
 
-we will be able to have a first version.
+we are getting closer to a first version.
 
 After, when we have modules, then VLC modules could be downloaded at runtime.

-Before compiling vlc, you must copy the video Dolby_Canyon.vob in the root of this project.

 ### Compile vlc.
 
 ```bash
 ./compile.sh
 ```
 
-All files (javascript and html) are in the folder build-emscripten. You can see localy vlc by
-lanch a webserver on your computer.
+You can run it locally by launching a webserver on your computer.
 
 ```bash
-source emsdk-portable/emsdk_env.sh
-cd vlc/build-emscripten
-emrun --no_browser --port 8080 experimental.html --emrun
+source emsdk/emsdk_env.sh
+emrun --no_browser --port 8080 vlc.html --emrun
 ```
 
-And seeing the result in firefox at url : http://localhost:8080/experimental.html
-You can also put the generated files on a server and access to it normaly.

 ## Run
 
-Currently only Firefox is able to run vlc.js, but you need to enable some features in Firefox first.
-Type about:config in the Location Bar and press Enter to see all Preferences.
+It should be able to run in all browsers and OSes except Chrome in MacOS where there is a [bug](https://code.videolan.org/b1ue/vlc/issues/36) 
+
+|| Chrome 77.0.3865.120 (stable) | Firefox Dev Edition (70.0b14) (*)|

 ## Hack
 
-To can compile vlc.js, we need to apply patches on the main VLC.
-
-Emscripten being in devlopment, some patches need to applied too to fix issues and missing features.
+To compile vlc.js, we need to apply patches on VLC master.
 
-All the patches are grouped in 2 folders:
+All the patches are grouped in this folder:
  * patch_vlc: vlc patches
- * patch_emscripten : emscripten patches
+
+There are also patches to enable dav1d and dvd contribs.
 
 The script compile.sh sets up the toolchain, clones vlc, compiles it, generates the module_list and compiles all into a html + js pages.
