+<img src="esptool-gui-screenshot.png?raw=true" alt="esptool-gui screenshot" width="500px">
+
+## Installing
+
+You can download prebuilt binaries from the [releases section](https://github.com/Rodmg/esptool-gui/releases).
+
+## Building
+
+### OSX
+
+1. You should have Qt5 and QtCreator developer tools installed in your system (https://www.qt.io/developers/). tested with Qt 5.6.0 and Qt Creator 4.0.0.
+2. Clone this repo and open ``esptool-gui.pro`` with Qt Creator, build from there.
+3. For deploying the application, you should include the Qt libraries in te app bundle, you can use the mac deployment tool, more info here: http://doc.qt.io/qt-5/osx-deployment.html
+
+### Windows and Linux
+
+I haven't tested this in Windows and Linux, however building should be more or less straight forward. The only special build step that should change is the part where the [esptool-ck binary](https://github.com/igrr/esptool-ck/releases) is bundled, you should bundle the correct version for your operating system. You may also need to change the path in the code.
