+## Uninstalling Zed
+
+### Standard Uninstall
+
+If Zed was installed using the default installation script, it can be uninstalled by supplying the `--uninstall` flag to the `zed` shell command
+
+```sh
+zed --uninstall
+```
+
+If there are no errors, the shell will then prompt you whether you'd like to keep your preferences or delete them. After making a choice, you should see a message that Zed was successfully uninstalled.
+
+In the case that the `zed` shell command was not found in your PATH, you can try one of the following commands
+
+```sh
+$HOME/.local/bin/zed --uninstall
+```
+
+or
+
+```sh
+$HOME/.local/zed.app/bin.zed --uninstall
+```
+
+The first case might fail if a symlink was not properly established between `$HOME/.local/bin/zed` and `$HOME/.local/zed.app/bin.zed`. But the second case should work as long as Zed was installed to its default location.
+
+If Zed was installed to a different location, you must invoke the `zed` binary stored in that installation directory and pass the `--uninstall` flag to it in the same format as the previous commands.
+
+### Package Manager
+
+If Zed was installed using a package manager, please consult the documentation for that package manager on how to uninstall a package.

 ## Troubleshooting
 
 Linux works on a large variety of systems configured in many different ways. We primarily test Zed on a vanilla Ubuntu setup, as it is the most common distribution our users use, that said we do expect it to work on a wide variety of machines.
