# Topics

Topics are Hylo's tagging system that help organize and discover content across the platform. They use the hashtag format (#) and serve as a way to categorize and connect related posts and chats.&#x20;

If you add a #Topic to your posts or chats, it will show up in that #Topic's Stream, with all the Posts and Chats with that #Topic. If there is a chatroom associated with a #topic, your chat / post will show up in that chatroom.&#x20;

## Creating & Using Topics

* **Add a Topic**: Type "#" followed by your topic name when creating a post
* **Topic Suggestions**: As you type, Hylo will suggest existing topics from your groups
* **New Topics**: If your topic doesn't exist, simply finish typing to create a new one
* **Multiple Topics**: Add as many topics as relevant to your post

## #Topic-Based Chat

Chat rooms are created manually by a group steward and are connected to a topic. Any posts that use a #topic connected to a chat room will make it appear in the chat room if it exists. See [Creating Chat Rooms](https://hylozoic.gitbook.io/hylo/hylo-user-manual/chat-on-hylo#creating-a-chat-room).&#x20;

## #Topic Stream
