 ### How do I know if my meter is supported?
 
-To make sure your meter will work with the Home Assistant Glow, you have to look for the **imp/kWh** rate (see picture). Note the value, because it will be of importance at a later stage to configure the `.yaml` file.

 ## Get started
 
-Once you are done connecting all the hardware, we'll get started with the configuration for ESPHome. In this repository you will find the file [home_assistant_glow.yaml][file], which you can copy into the `esphome` folder of your Home Assistant config. Adjust the value `pulse_rate` under **substitutions** to the value on your meter ([how do I find my imp/kWh rate?](#how-do-i-know-if-my-meter-is-supported)), by default the value is `1000` in the yaml file. Finally go through the installation wizard of ESPHome and flash the ESP32/8266.
