 # litsimaja
 
 Projekt Litsimaja - Lapikute tagatoa seintele programmeeritavad ARGB ribad
+
+#### Running the program
+```python run.py```
+
+#### Running with emulation
+This is mainly for testing, development.
+
+In ``lib/Litsimaja.py`` change the following:
+```
+# from lib.strip.TkinterStrip import TkinterStrip
+
+    def __init__(self):
+        self._strip = PixelStrip(290, 18, 800000, 10, False, 255, 0, 4104)
+```
+to
+```
+from lib.strip.TkinterStrip import TkinterStrip
+
+    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.
