# Zulip User Documentation Zulip is a group chat app. Its most distinctive characteristic is that conversation within an organization is divided into “**streams**” and further subdivided into “**topics**”, so that much finer-grained conversations are possible than with IRC or other chat tools. Most people use Zulip on the Web. There are also mobile apps for Android/iOS, and desktop apps for Mac/Linux/Windows, which can be downloaded [here](https://zulipchat.com/apps/). One Zulip account, associated with a particular company, project, or team, is known as an **organization**. --- ## Account Basics * [Change your name](/help/change-your-name) * [Change your email address](/help/change-your-email-address) * [Change your password](/help/change-your-password) * [Change your settings](/help/change-your-settings) * [Change your avatar](/help/change-your-avatar) * [Change your language](/help/change-your-language) * [Change the date and time format](/help/change-the-date-and-time-format) * [Move the users list to the left sidebar](/help/move-the-users-list-to-the-left-sidebar) * [Join a Zulip organization](/help/join-a-zulip-organization) * [Signing in](/help/signing-in) * [Signing out](/help/signing-out) * [Deactivate your account](/help/deactivate-your-account) ##
