 - You will need to build `crates/cli` and make its binary available in `$PATH` with the name `zed`.
 - You will need to build `crates/zed` and put it at `$PATH/to/cli/../../libexec/zed-editor`. For example, if you are going to put the cli at `~/.local/bin/zed` put zed at `~/.local/libexec/zed-editor`. As some linux distributions (notably Arch) discourage the use of `libexec`, you can also put this binary at `$PATH/to/cli/../../lib/zed/zed-editor` (e.g. `~/.local/lib/zed/zed-editor`) instead.
-- If you are going to provide a `.desktop` file you can find a template in `crates/zed/resources/zed.desktop.in`, and use `envsubst` to populate it with the values required. This file should also be renamed to `$APP_ID.desktop` so that the file [follows the FreeDesktop standards](https://github.com/zed-industries/zed/issues/12707#issuecomment-2168742761).
+- If you are going to provide a `.desktop` file you can find a template in `crates/zed/resources/zed.desktop.in`, and use `envsubst` to populate it with the values required. This file should also be renamed to `$APP_ID.desktop` so that the file [follows the FreeDesktop standards](https://github.com/zed-industries/zed/issues/12707#issuecomment-2168742761). You should also make this desktop file executable (`chmod 755`).
 - You will need to ensure that the necessary libraries are installed. You can get the current list by [inspecting the built binary](https://github.com/zed-industries/zed/blob/935cf542aebf55122ce6ed1c91d0fe8711970c82/script/bundle-linux#L65-L67) on your system.
 - For an example of a complete build script, see [script/bundle-linux](https://github.com/zed-industries/zed/blob/935cf542aebf55122ce6ed1c91d0fe8711970c82/script/bundle-linux).
 - You can disable Zed's auto updates and provide instructions for users who try to update Zed manually by building (or running) Zed with the environment variable `ZED_UPDATE_EXPLANATION`. For example: `ZED_UPDATE_EXPLANATION="Please use flatpak to update zed."`.
