 #### Running with emulation
 This is mainly for testing, development.
 
-In ``lib/Litsimaja.py`` change the following:
-```
-# from lib.strip.TkinterStrip import TkinterStrip
+Create .env file:
+```cp .env.example .env```
 
-    def __init__(self):
-        self._strip = PixelStrip(290, 18, 800000, 10, False, 255, 0, 4104)
-```
-to
-```
-from lib.strip.TkinterStrip import TkinterStrip
+and see: ```USE_EMULATOR```
 
-    def __init__(self):
-        self._strip = TkinterStrip(290, 18, 800000, 10, False, 255, 0, 4104)
-```
 Now when you run the program, you will see a Tkinter window pop up with a rectangle simulating the LED strip.
-
-Don't commit this change.
