 This action takes a yaml file for an ESPHome device and will compile and output
-the build firmware file and a partial `manifest.json` file that can be used to flash 
+the build firmware file and a partial `manifest.json` file that can be used to flash
 a device via [ESP Web Tools](https://esphome.github.io/esp-web-tools).
 
 ## Example usage
 
 ```yaml
-
 uses: esphome/build-action@v1
 with:
   yaml_file: my_configuration.yaml
-
 ```
 
 This action is used by the [ESPHome publish workflow](https://github.com/esphome/workflows/blob/main/.github/workflows/publish.yml) that is used to compile firmware and publish simple GitHub pages sites for projects.

 ## Output files
 
-This action will output a folder named with the output `name` and will contain two files, `{name}.bin` and `manifest.json`.
+This action will output a folder named with the output `name` and will contain three files:
+
+- `manifest.json` - This goes into the `builds` section of an esp-web-tools manifest.json.
+- `{name}.factory.bin` - The firmware to be flashed with esp-web-tools.
+- `{name}.ota.bin` - The firmware that can be flashed over-the-air to the device using the [Managed Updated via HTTP Request](https://esphome.io/components/update/http_request).
