+# Build & Install Cadius Action
+
+This action will build and install the Cadius tool for creating and modifying Apple II ProDOS disk images.
+
+* The tip-of-tree version from https://github.com/mach-kernel/cadius is used.
+* Cadius is built and installed, so later steps can use `cadius` commands directly.
+
+The action has no inputs or outputs.
