Getting started

From the project's README ("Installing"):

Install MIDIMON with the web installer or python3 fm1-base/tools/fm1install.py midimon-X.Y.fwsc, over the stock firmware, another custom firmware (tested over Felucca) or an earlier MIDIMON. Its settings live in the flash's data area; another firmware's settings at 0xFC000 are left alone.

Releases are built on GitHub by The Firmware Hub's shared workflow (zvenson/fm1-build) and carry a build attestation. To check a file:

gh attestation verify midimon-X.Y.fwsc --repo ignis32/midimonitorfm1 \
    --signer-workflow zvenson/fm1-build/.github/workflows/build.yml
