+
+## Keyboard
+- `h` - Show help
+- `c`- Toggle Histogram
+- `e`- Toggle EXIF data
+- `d`- Cycle [[#Detail Views]] (default off)
+- `a` - Toggle image filtering (default off)
+- `g` - Toggle grid (only visible at pixel level)
+- `r`- Rotate image 90 degrees clockwise
+- `q` - Quit

-## Emscripten
+Generate build files and trigger build
+```
+cmake .
+cmake --build .
+```
 
-**Building**
+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
+```
 
-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).
+`tview` is now installed on your system
