-## Brief history
+## :hourglass_flowing_sand: Brief history
 
 This theme is based on the original [LoveIt](https://github.com/dillonzq/LoveIt) theme. The original theme was loved by many users, but since May 2020 it has not been maintained.
 
 We tried to contact the theme [owner](https://github.com/dillonzq), but without success. The contributors have opened an [issue](https://github.com/dillonzq/LoveIt/issues/514) and asked if the theme is still supported, but we also did not receive any response.
 
 So we decided to create and maintain the theme with a new name, keeping the original style, but continuously improving it. Feel free to contribute to this theme 😊.

 You can build the theme documentation locally by using a [devcontainer](https://code.visualstudio.com/docs/remote/containers) or by manually install the [`Hugo`](https://gohugo.io/getting-started/installing).
 The main advantage of the `devcontainer` is that you will have a preconfigured container with all tools required for developing and building the theme documentation.
