-- **Multi-source:** Recommend items from Popular, latest, user-based, item-based and collaborative filtering.
+- **Multi-source:** Recommend items from latest, user-to-user, item-to-item, collaborative filtering and etc.
 - **AutoML:** Search the best recommendation model automatically in the background.
 - **Distributed prediction:** Support horizontal scaling in the recommendation stage after single node training.
 - **RESTful APIs:** Expose RESTful APIs for data CRUD and recommendation requests.
 - **Online evaluation:** Analyze online recommendation performance from recently inserted feedback.
-- **Dashboard:** Provide GUI for data management, system monitoring, and cluster status checking.

 ## Quick Start
 
 The playground mode has been prepared for beginners. Just set up a recommender system for GitHub repositories by the following commands.
 
-- Linux/macOS:
-
-```bash
-curl -fsSL https://gorse.io/playground | bash
-```
-
-- Docker:
-
 ```bash
 docker run -p 8088:8088 zhenghaoz/gorse-in-one --playground
 ```
 
 The playground mode will download data from [GitRec](https://gitrec.gorse.io/) and import it into Gorse. The dashboard is available at `http://localhost:8088`.
