+The **`IMCF Uni Basel`** update-site will supply the necessary `.jar` to run the functions contained in this package, but alternatively, the most up-to-date `.jar` for this package can be always found on the [Scijava Maven repository][scijava-1.5.0], which links to, for example, the `1.5.0` version of `python-imcflibs`.
+
+If you manually download the `.jar` from Scijava, extract the zip folder, and place the `.jar` file in the `\jars` folder of your Fiji installation, e.g `C:\Tools\Fiji.app\jars\`. 
+
+### Testing Installation
+
+To check the package's correct installation in Fiji, search for *Script Interpreter* in the Search bar, and type `:lang python`, followed by e.g. `import imcflibs.imagej.misc`. If no errors are shown, the installation was successful. Alternatively, you can scroll in the sidebar of the Interpreter to search for imcflibs.
