 Building with Emscripten works with emsdk 2.0.31 and above.
 
-Currently there is no LibLZMA support upstream; for this we suggest to apply
-the provided patch in this folder to your emsdk installation.
-
-For convenience, a Dockerfile is supplied that does this patches for you
-against upstream emsdk docker. Best way to use it:
-
-Build the docker image:
 ```
-  docker build -t emsdk-lzma .
-```
-
-Build the host tools first:
-```
-  mkdir build-host
-  docker run -it --rm -v $(pwd):$(pwd) -u $(id -u):$(id -g) --workdir $(pwd)/build-host emsdk-lzma cmake .. -DOPTION_TOOLS_ONLY=ON
-  docker run -it --rm -v $(pwd):$(pwd) -u $(id -u):$(id -g) --workdir $(pwd)/build-host emsdk-lzma make -j5 tools
-```
-
-Next, build the game with emscripten:
-
-```
-  mkdir build
-  docker run -it --rm -v $(pwd):$(pwd) -u $(id -u):$(id -g) --workdir $(pwd)/build emsdk-lzma emcmake cmake .. -DHOST_BINARY_DIR=$(pwd)/build-host -DCMAKE_BUILD_TYPE=RelWithDebInfo -DOPTION_USE_ASSERTS=OFF
-  docker run -it --rm -v $(pwd):$(pwd) -u $(id -u):$(id -g) --workdir $(pwd)/build emsdk-lzma emmake make -j5
+  ./emscripten-build.sh
 ```
 
 And now you have in your build folder files like "openttd.html".
