+## :warning: Not needed anymore
+
+As `image/jxl` is now supported by [shared-mine-info 2.2](https://gitlab.freedesktop.org/xdg/shared-mime-info/-/releases/2.2), it should not be necessary anymore to install this plugin.
+
+You can test if your system correctly understand the MIME type of JPEG XL image by obtaining a JPEG XL image, e.g. with
+```bash
+wget https://raw.githubusercontent.com/libjxl/conformance/master/testcases/bicycles/input.jxl
+```
+and with that sample JPEG XL file `input.jxl` (or any other valid JPEG XL file), run any of the following commands:
+```bash
+xdg-mime query filetype input.jxl
+file --mime-type input.jxl
+mimetype input.jxl
+```
+If the output contains `image/jxl` you are all set!
+
+
+## JPEG XL MIME type
+
+If not already installed by the [Installing section of BUILDING.md](../../BUILDING.md#installing), then it can be done manually:
+
+### Install
+```bash
+sudo xdg-mime install --novendor image-jxl.xml
+```
+
+Then run:
+```
+update-mime --local
+```
+
+
+### Uninstall
+```bash
+sudo xdg-mime uninstall image-jxl.xml
+```
