+Instruction for building OCCT for ASRV
+======================================
+
+Build using regular native compiler
+-----------------------------------
+
+1. Make sure the directory 3rdparty is next to occt. It must contain the following products:
+    freetype
+    tcltk
+2. Change current directory to adm/scripts.
+3. On Windows run the script cmake_gen.bat.
+   On Linux run 'cmake_gen.sh' for release build and 'cmake_gen.sh -d' for debug build.
+4. Go to build directory and build and install OCCT.
+   On Windows run:
+    build.bat
+    build.bat vc14 64 d
+    install.bat
+    install.bat vc14 64 d
+   On Linux run:
+    make -j4 install
+
+Build using Emscripten to generate libs for Web assembly
+--------------------------------------------------------
+
+1. Make sure you have installed Emscripten. For that you can make sure occ-web3d directory 
+   is next to occt. It must contain fips\fips-sdks\emsdk.
+2. Make sure the directory 3rdparty is next to occt. It must contain the following products:
+    freetype wasm build
+3. Change current directory to adm/scripts.
+4. Run the script wasm_build.bat (wasm_build.sh on Linux).
+5. Copy installed files from work/wasm to the 3rdparty under occt77-wasm.
