+
+#### Running the program
+```python run.py```
+
+#### Running with emulation
+This is mainly for testing, development.
+
+Create .env file:
+```cp .env.example .env```
+
+and see: ```USE_EMULATOR```
+
+Now when you run the program, you will see a Tkinter window pop up with a rectangle simulating the LED strip.
