-What's My Window (WMW) is an utility for reading active application from the OS
+What's My Window (WMW) is a simple C++ utility for detecting active application from the OS, designed to display activity in code editors in the Internet.
+
+WMW uses Windows API to get the foreground window and output its name and elapsed time using the following scheme:
+```
+MyAppName hh:mm:ss
+```
+
+where `MyAppName` is the application name and then comes the time.
+
+# Installation
+WMW is currently available to use on Windows (though Mac and Linux releases are also planned). The binary is built by pasting the following line into your terminal:
+```
+g++ .\main.cpp .\processInfo.cpp -o wmw.exe -lpsapi
+```
+
+# Configuration
+
+WMW can be widely personalised to the user's needs by changing the values in `settings.hpp`:
+
+`unsigned int interval` - the interval between two window requests in miliseconds (default: `1000`)
+
+`string windowStartup` - the text to display on application startup (used for future translation purposes)
+
+`codeEditors` - a list of key/value pairs of the applications' process names and the corresponding window titles\
+(Tip: process names can be obtained via the details tab of the Task Manager)
+
+**Remember**: the settings are stored in the WMW binary and you have to rebuild it to apply the changes!
+
+# To Do
+
+ - Add file name/project name detection for the code editors - the window title usually contains them
+ - Improve the example project by making it refresh automatically every second
+ - Add the ability to personalise the output structure in the config, e.g. adding the process name or the PID
+
+Feel free to open a pull request if you develop a solution of one of these (new ideas are also welcome)!
+
+
+# Example 
+The repository contains an example project using the WMW interface - a basic functionality of HTTP display of the current window.
+To open it, install Node.js and NPM and run `npm install` in the `example` folder to download the Node libraries and then `node main.js` to run the app.
+Then open [localhost:5500](http://localhost:5500) in your browser and you should see the WMW output!
