+```bash
 $ cp -i secrets.yaml{.sample,}
 $ cp -i templates/secrets.yaml{.sample,}
 
 # Edit both secrets.yaml files.
 
-$ ./reflash.sh compile ''

+To flash all devices (automatically prioritizes OTA and skips prompts):
+
+```bash
+$ nix develop --command make flash-all -j4
 ```
 
-or
+To flash a single device:
 
-```
-$ esphome run file.yaml

-Look up list of runnable configurations inside `reflash.sh` script.
+Alternatively, you can drop into the development shell and run `esphome` directly:
+
+```bash
+$ nix develop
+$ esphome run bathroomheater.yaml
+```
+
+**Note:** The Makefile automatically tracks dependencies (including `!include` files and local `external_components` directories). It will natively evaluate changes and only recompile what has actually changed since the last run.
