+
+### About
+
+SDL2 Terminal Emulator based on [libsdl2](http://www.libsdl.org), [libvterm](http://www.leonerd.org.uk/code/libvterm/) and [SDL_fox](https://github.com/palomena/SDL_fox).  
+Should be compatible with all POSIX compliant systems and probably also win32.
+
+![Screenshot](data/screenshot.png)
+
+Originally developed as a standalone terminal emulator, meaning all of the
+vt100 and xterm behind the scenes management had been implemented from scratch.
+Turned out ok-ish, but a few edge cases kept failing. Did not want to
+go through 3000+ loc of cryptic csi sequence parsing and vt100 handling. 
+Heard of libvterm and never looked back since. Don't reimplement the wheel.
+
+Single source file, less than 1000 loc, kept as simple and minimal as possible.
+
+![Screenshot](data/terminal.png)
+
+### Features
+- Clipboard handling (Copy+Paste)
+- Visual terminal bell
+- Blinking cursor
+- Colors
+- Font zoom on mousewheel/touchpad event
+- Runtime selectable renderer backend (software, opengl, etc)
+- window resize triggers buffer and child process resize
+- Fast, due to SDL_fox prerendered font rendering
+- Easily hackable by playing around with the accessible sourcecode
+- Probably runs on a posix compliant toaster (if SDL supports it)
+
+### Missing features / Future improvements
+- Scrollback buffer
+- Performance
+	- damage triggers full screen redraw, where partial update would be sufficient
+
+### Build
+
+1. Install libsdl2, libsdlfox, make
+2. `git clone [REPOSITORY URL]`
+3. cd ./sdlterm
+4. `make`
+5. A *wild* sdlterm application should appear in the ./build directory
