-# Installing
-## Requirements to Run
-- SDL2
-- OpenGL
-- Libexiv2
-
-## Requirements to build
-In addition to the run requirements
-- CMake
-- C++ Compiler (g++/clang++)
-### On Ubuntu
+Use build_win32.bat or directly:
 ```
-apt install --no-install-recommends build-essential cmake libsdl2-dev libexiv2-dev mesa-utils
-```
-### On Debian
-```
-apt install --no-install-recommends build-essential cmake libsdl2-dev libexiv2-dev mesa-utils
-```
-### On Arch
-```
-pacman -Sy sdl2 mesa-utils exiv2 cmake base-devel

 ```
 
-## Building
-Clone the repository
+## Linux and similar Unixes
+
+Use our Makefile or directly:
 ```
-git clone https://git.dws.rip/dubey/tview.git
+c++ `sdl2-config --cflags` -I .. -I ../.. -I ../../backends
+  main.cpp ../../backends/imgui_impl_sdl2.cpp ../../backends/imgui_impl_opengl3.cpp ../../imgui*.cpp
+  `sdl2-config --libs` -lGL -ldl
 ```
 
-Change directory into the repository
+## macOS
+
+Use our Makefile or directly:
 ```
-cd tview
+brew install sdl2
+c++ `sdl2-config --cflags` -I .. -I ../.. -I ../../backends
+  main.cpp ../../backends/imgui_impl_sdl2.cpp ../../backends/imgui_impl_opengl3.cpp ../../imgui*.cpp
+  `sdl2-config --libs` -framework OpenGl -framework CoreFoundation
 ```
 
-Generate build files and trigger build
-```
-cmake .
-cmake --build .
-```
+## Emscripten
 
-You will now have a file called `tview` in the repository root, you can copy this into your path:
-```
-sudo mv ./tview /usr/local/bin/tview
-```
+**Building**
 
-`tview` is now installed on your system
+You need to install Emscripten from https://emscripten.org/docs/getting_started/downloads.html, and have the environment variables set, as described in https://emscripten.org/docs/getting_started/downloads.html#installation-instructions
+
+- Depending on your configuration, in Windows you may need to run `emsdk/emsdk_env.bat` in your console to access the Emscripten command-line tools.
+- You may also refer to our [Continuous Integration setup](https://github.com/ocornut/imgui/tree/master/.github/workflows) for Emscripten setup.
+- Then build using `make -f Makefile.emscripten` while in the current directory.
+
+**Running an Emscripten project**
+
+To run on a local machine:
+- `make -f Makefile.emscripten serve` will use Python3 to spawn a local webserver, you can then browse http://localhost:8000 to access your build.
+- Otherwise, generally you will need a local webserver. Quoting [https://emscripten.org/docs/getting_started](https://emscripten.org/docs/getting_started/Tutorial.html#generating-html):<br>
+_"Unfortunately several browsers (including Chrome, Safari, and Internet Explorer) do not support file:// [XHR](https://emscripten.org/docs/site/glossary.html#term-xhr) requests, and can’t load extra files needed by the HTML (like a .wasm file, or packaged file data as mentioned lower down). For these browsers you’ll need to serve the files using a [local webserver](https://emscripten.org/docs/getting_started/FAQ.html#faq-local-webserver) and then open http://localhost:8000/hello.html."_
+- Emscripten SDK has a handy `emrun` command: `emrun web/index.html --browser firefox` which will spawn a temporary local webserver (in Firefox). See https://emscripten.org/docs/compiling/Running-html-files-with-emrun.html for details.
+- You may use Python 3 builtin webserver: `python -m http.server -d web` (this is what `make serve` uses).
+- You may use Python 2 builtin webserver: `cd web && python -m SimpleHTTPServer`.
+- If you are accessing the files over a network, certain browsers, such as Firefox, will restrict Gamepad API access to secure contexts only (e.g. https only).
