-
-          ### Install
-          Download the pack matching your frontend, extract to the BIOS directory.
-
-          Packs over 2 GB are split into numbered volumes (.zip.001, .zip.002).
-          Download every part, then either open the .001 file directly with
-          7-Zip / PeaZip, or join the parts first:
-          - Linux/macOS: \`cat PackName.zip.0* > PackName.zip\`
-          - Windows (cmd): \`copy /b PackName.zip.001+PackName.zip.002 PackName.zip\`
