+Uninstallation
+^^^^^^^^^^^^^^
+
+To remove the MNE-Python distribution provided by our installers above:
+
+1. Remove relevant lines from your shell initialization scripts if you
+   added them at installation time. To do this, you can run from the MNE Prompt:
+
+   .. code-block:: bash
+
+       $ conda init --reverse
+
+   Or you can manually edit shell initialization scripts, e.g., ``~/.bashrc`` or
+   ``~/.bash_profile``.
+
+2. Follow the instructions below to remove the MNE-Python conda installation for your platform:
+
+   .. tab-set::
+       :class: uninstall-selector-tabset
+
+       .. tab-item:: Linux
+           :name: uninstall-linux
+
+           In a BASH terminal you can do:
+
+           .. code-block:: bash
+
+               $ which python
+               /home/username/mne-python/1.8.0_0/bin/python
+               $ rm -Rf /home/$USER/mne-python
+               $ rm /home/$USER/.local/share/applications/mne-python-*.desktop
+
+       .. tab-item:: macOS
+           :name: uninstall-macos
+
+           You can simply `drag the MNE-Python folder to the trash in the Finder <https://support.apple.com/en-us/102610>`__.
+
+           Alternatively, you can do something like:
+
+           .. code-block:: bash
+
+               $ which python
+               /Users/username/Applications/MNE-Python/1.8.0_0/.mne-python/bin/python
+               $ rm -Rf /Users/$USER/Applications/MNE-Python  # if user-specific
+               $ rm -Rf /Applications/MNE-Python              # if system-wide
+
+       .. tab-item:: Windows
+           :name: uninstall-windows
+
+           To uninstall MNE-Python, you can remove the application using the `Windows Control Panel <https://support.microsoft.com/en-us/windows/uninstall-or-remove-apps-and-programs-in-windows-4b55f974-2cc6-2d2b-d092-5905080eaf98>`__.
