 == Binary Releases
 
 Our official LibrePCB xref:installation:index.adoc[binary releases] contain
 the `librepcb-cli` executable next to the GUI application, so usually no
-separate installation is needed. But there are two exceptions: The AppImage
-and the macOS bundle.
+separate installation is needed.
 
-=== Linux AppImage
-
-*Download {appimage-url}[{appimage-filename}], make it executable and run it:*
+MacOS::
+  You need to invoke the CLI with the full path to the binary:
++
+[source,bash]
+----
+/Applications/LibrePCB.app/Contents/MacOS/librepcb-cli --help
+----
 
+Linux AppImage::
+  The LibrePCB AppImage also contains the CLI, but since it's a single binary
+  you can't run `librepcb-cli` explicitly. Instead, you have to rename the
+  AppImage to `librepcb-cli` to make it acting as the CLI (or create a symlink):
++
 [source,bash,subs="attributes"]
 ----
 wget "{appimage-url}"
 chmod +x ./{appimage-filename}
-./{appimage-filename}
+mv ./{appimage-filename} ./librepcb-cli
+./librepcb-cli --help
 ----
 
-=== macOS Bundle
-
-Download the portable `*.dmg` file matching your CPU architecture:
-
-* *Intel (x86_64)*: {bundle-url}[{bundle-filename}]
-* *Apple Silicon (arm64)*: {bundle-arm64-url}[{bundle-arm64-filename}]
-
-Double-click the downloaded file in Finder. Then drag and drop the app
-onto the "Applications" folder in Finder.

-The recommended way to install LibrePCB is to use the online installer.
-It provides the following features:
-
-- Installs a maintenance tool to easily download and install updates.
-- Creates start menu entries for LibrePCB and the maintenance tool.
-- Optionally registers `*.lpp` files, so LibrePCB projects can be opened
-  with a double-click in the file manager.
+The recommended way to install LibrePCB is to use the installer.
 
 *Just download and run {installer-url}[{installer-filename}].*
 Afterwards you'll find LibrePCB in your start menu.
 
+[IMPORTANT]
+====
+Unfortunately we're not able yet to sign our Windows installer (it's quite
+expensive to do it). Therefore Windows might warn that the publisher of the
+installer is unknown. This is normal for binaries without paying for a
+signature, therefore just click on btn:[More info] and then btn:[Run anyway]
+to skip the warning.
+====
+
+[NOTE]
+====
+For automated (unattended) installation, please check out the command-line
+parameters of the Inno Setup framework

 == Portable Package
 
 Alternatively you could run LibrePCB without installing it. But then you don't
-get an update mechanism, no start menu entries are created, and `*.lpp` files
-will not be registered.
+get start menu entries and LibrePCB file extensions won't be registered so
+you can't open LibrePCB projects with a double-click in the file manager.
 
 Download and extract {zip-url}[{zip-filename}], then run the contained file
 `bin\librepcb.exe`.
