+### Manual Installation of Snapshot Release
+
+Download the current snapshot release from [GitHub](https://github.com/SAP/cf-cli-java-plugin/releases/tag/snapshot).
+This is intended for experimentation and might fail.
+
+To install a new version of the plugin, run the following:
+
+```sh
+# on Mac arm64
+cf install-plugin -f https://github.com/SAP/cf-cli-java-plugin/releases/download/snapshot/cf-cli-java-plugin-macos-arm64
+# on Windows x86
+cf install-plugin -f https://github.com/SAP/cf-cli-java-plugin/releases/download/snapshot/cf-cli-java-plugin-windows-amd64
+# on Linux x86
+cf install-plugin -f https://github.com/SAP/cf-cli-java-plugin/releases/download/snapshot/cf-cli-java-plugin-linux-amd64
+```
+
 ### Updating from version 1.x to 2.x
 
 With release 2.0 we aligned the convention of the plugin having the same name as the command it contributes (in our case, `java`).
