One-page guide: Conda Community Chat using Element

The conda ecosystem is migrating has migrated from Slack and other platforms to Element for community chat. This is your one-page guide to getting up and running with Element.
Note that this will have only a minimal impact of current Gitter users.



  • Element: A chat client that works with the Matrix protocol. Element is also available as a web site.
  • Matrix: An open protocol for chat.
  • and Matrix-compatible chat providers that host conda community chat rooms.

Element enables you to connect to and participate in conda community chat rooms hosted on the (matrix-compatible) and services.

Think of this as similar to email: Email clients (like Outlook or Thunderbird) use email protocols to connect you to email providers (like your school or employer). Element does this for chat.


  • Rooms, such as the main conda chat room, are where chat happens.
  • Spaces group related rooms together. Spaces can also link to other related spaces.

All known conda-related chat rooms are linked to from the conda space. conda-forge has it’s own space, which is linked to from the conda space.

Change the room order in a space

The order of rooms in a space initially appears to be random, in both the sidebar listing the rooms you are a member of, and in the space’s home page. Well, neither is random, but they may not be that helpful.

To change the order of the rooms you belong to in the sidebar:

  1. Hover over the top of the Rooms list in the room’s sidebar
  2. Click the ellipsis “” that appears when you hover
  3. This displays the list options. Select the Sort by and Appearance options you want.


This shows the options to sort the sidebar room list alphabetically

To change the order of the rooms and spaces on the space home page:

  1. You can’t. :frowning_face:
