+# M-1 firmware options in the installer
+
+The M-1 offers two WLED firmwares in the installer, both served from GitHub Pages:
+
+- WLED-MM 14.5.1 (default) from ApolloAutomation/WLED-MM-M1. Two hardware revisions:
+  - Rev6: https://apolloautomation.github.io/WLED-MM-M1/Rev6_14.5.1/manifest.json
+  - Rev4: https://apolloautomation.github.io/WLED-MM-M1/14.5.1/manifest.json
+- WLED 16.0.1 (Rev6 only) from ApolloAutomation/WLED-M1:
+  - https://apolloautomation.github.io/WLED-M1/manifest.json
+
+Rev6 with WLED-MM 14.5.1 is the default because that is the hardware being sold and the firmware
+shipped on it today. WLED 16.0.1 is a single merged full-install image (bootloader, partition
+table, otadata, application, and LittleFS factory config) built from ApolloAutomation/WLED-M1.
+Its manifest sets new_install_prompt_erase, so esp-web-tools prompts a full erase, which is what
+guarantees a factory-fresh 64x64 boot. It is offered for Rev6 only.
+
+Customers already on WLED-MM 14.5.1 can OTA to 16.0.1 with the M-1_ota.bin app-only image
+(same partition table preserves settings); the installer only serves the first-flash full image.
+
+Hosting: WLED-MM-M1 serves the 14.5.1 manifests from committed files via legacy branch Pages.
+WLED-M1 serves the 16.0.1 manifest through an Actions Pages workflow
+(.github/workflows/apollo-pages.yml) that publishes manifest.json plus M-1_full_install.bin
+from the latest GitHub release, so the 16MB image never enters git history.
