+Example of Installing Fiji with the IJP ImageJ Launcher on Mac OS X Arm64
+-------------------------------------------------------------------------
+
+#### 1. Download FIJI without JRE
+
+Go to https://fiji.sc/ and select "Download the no-JRE version".
+That should het you file called `fiji-nojre.zip`
+
+#### 2. Unzip the `fiji-nojre.zip` in the directory of choice
+
+In Mac OS X, if you double-click on the file `fiji-nojre.zip`
+You should get `Fiji.app` click and select "show Content"
+
+#### 3. Create place for Java (JRE)
+
+Inside `Fiji.app` create directory `java`.
+Next to directories that are already there, like `Contents`, `images`, `jars`, ...
+
+#### 4. Download Java JRE or JDK,
+
+In browser open https://adoptium.net/temurin/releases/
+Select:
+
+* operating system: `macOS`
+* architecture: `aarch64` also know as Apple Silicon or Arm64
+* package: `jre` (`jdk` is fine too, is larger supports Java compilation)
+* version: `11` (`17` will work too, but you will not have JavaScript available, if you use it)
+
+Click on `tar.gz` button and download to the `java` directory you created earlier.
+You should have file like `OpenJDK11U-jre_x64_windows_hotspot_11.0.19_7.tar.gz`.
+
+#### 5. Uncompress into the `java` directory
+
+That will create directory like `jdk-11.0.19+7-jre`
+
+#### 6. Download IJP ImageJ Launcher to Fiji.app directory
+
+Go to [Releases] and download `???` and `???.???`
+
+#### 7. Start ImageJ
+
+In Fiji.app double-click on `???.???` (note the extension ???) that should start FIJI.
+
+You can also create an alis on the desktop to avoid navigating to Fiji.app directory each time.
+Press ??? and ??? and drag  `???.???` to the Desktop.
+It will create an alias.
+Now you can double-click on the alias `???.???` on the Desktop to start Fiji.
+
+If you have problems installing, please report in [Discussions]
+
+Troubleshooting
+---------------
+
+1. Open command prompt (terminal).
+2. Navigate to `Fiji.app` directory
+3. Run IJP ImageJ Launch typing: `./ijp-imagej-launcher --debug`
+
+You should see diagnostic information about how `ijp-imagej-launcher` is attempting to start Fiji.
+The error messages shoudl help you to address the issue.
+Please use [Discussions] if you have additional questions
+
+Developer Setup
+---------------
+Information here is only applicable if you want to rebuild from sources.
+
+Setup Scala Native dependencies following instructions at:https://scala-native.org/en/v0.4.12/user/setup.html
+In brief, you will need the following installed: JDK, SBT, and LLVM/CLang.
+Details depend on OS.
+On Windows you will also need Visual Studio 2019 (the Community Editions is sufficient).
+Alternatively on Windows, you can build using WSL Linux prompt, in that case, follow Linux installation instructions.
+
+This should work with JDK 8 or newer, including the latest JDK 20.
+
+After requirements are installed, you should be able to build and run the launcher using command:
+
+```shell
+sbt run
+```
+
+You can pass additional command line arguments, for instance `--help`:
+
+```shell
+sbt "run --help"
+```
+
+Notice the use of quotes.
