 Releases are made through Maven and published to the [SciJava Maven
 repository][sj_maven]. The easiest way to use the lib is by adding the **`IMCF
 Uni Basel`** [update site][imcf_updsite] to your ImageJ installation.
 
 The [`pip install`able package][pypi] is probably only useful for two cases:
 running `pytest` (where applicable) and rendering [HTML-based API docs][apidocs]
-using [`pdoc`][pdoc]. Let us know in case you're having another use case 🎪 for

+## Installation Instructions
+
+Two ways of installing the `imcflibs` package are described here, the "*easy*"
+one through the *Fiji Update Sites* and the "*manual*" method using packages
+explicitly downloaded from [SciJava Maven][sj_maven].
+
+### 🧿 Default: Installation via Update Sites
+
+After a fresh install of [Fiji], navigate to *Help* -> *Update* and in the
+resulting window, press *Manage Update Sites*. Here, search for and tick the
+following necessary update sites for this package.
+
+- ImageJ
+- Fiji
+- 3D ImageJ-Suite
+- clij2
+- IJPB-plugins
+- IMCF Uni Basel
+- StarDist
+- CALM
+- TrackMate-Cellpose
+- TrackMate-Helper
+- TrackMate-StarDist
+- TrackMate-Weka
+- TrackMate-MorpholibJ
+
+The **`IMCF Uni Basel`** update-site will always provide the latest compatible
+combination of *official*`.jar` file to use this package.
+
+### 🏗 Alternative: SciJava Maven Package 👷
+
+💡 **IMPORTANT:** 💡 same as for the *default* installation previously
+described, you will need to enable **all Update Sites listed above** in your
+Fiji as well when using the method described here!
+
+The most up-to-date `.jar` (or any other published version, including
+pre-releases) for this package can be always found on the [Scijava Maven
+repository][sj_maven]. Navigate to the `python-imcflibs` folder, pick the
+desired version (can also be a pre-release) and download the contained `.jar`
+file, e.g. `python-imcflibs-2.0.0.jar`.
+
+Then simply that file in the `jars` folder of your Fiji installation, e.g
+`D:\Development\Fiji.app\jars\` or `/opt/Fiji.app/jars/`, possibly removing
+other versions of the same package from that folder - then (re-)start Fiji.
+
+If you'd prefer to use the cutting-edge version from GitHub, look into the
+[development instructions](DEVELOPMENT.md) for details.
+
+### Installation Testing
+
+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.
