+## Go build yourself
+### Prerequisites
+Install gulp (and gulp plugins)
+```bash
+npm install
+```
+### Build the font and export stylesheet
+Open [icomoon app](https://icomoon.io/app/#/select) and import [icomoon.json](icomoon.json). Choose _yes_ when beeing asked
+if you like to restore the settings stored in the configuration file.
+
+The next step is to click on **Generate font** and download the resulting archive. Extract it
+contents and you will find a [fonts](./fonts) directory next to a `style.css`. Replace the content of the `fonts` folder,
+merge the `style.css` with [devicon.css](./devicon.css) and follow the next step to build the final stylesheet.
+
+**Note** the merge is required, because some icons are defined as alias, this should be replaced
+with a more elegant solution to support automated build processing.
+
+### Build and minify stylesheet
+Run the following commands to build the resulting file `devicon.min.css`
+```bash
+gulp concat-css
+gulp minify-css
+```
