Signal Desktop is an Electron application that links with your Signal Android or Signal iOS app.

You can install it on a computer which already has the production version installed. It uses different data and install locations.

• Windows: You can find the most recent build here: https://updates.signal.org/desktop/beta.yml
• Mac: You can find the most recent build here: https://updates.signal.org/desktop/beta-mac.yml
• Linux: same instructions as the production install steps linked above, but run apt-get install signal-desktop-beta instead

You can find answers to a number of frequently asked questions on our support site: https://support.signal.org/. The community forum is another good place for questions: https://community.signalusers.org/.
