-To convert firboundaries.dat to GeoJSON:
-1. Create a subfolder in the root directory called /source/.
-2. Paste firboundaries.dat in the created folder.
-3. Run main.py.
+Alpha version including GUI
 
-firboundaries.geojson is created in /output/
+- Unzip the release version.
+- Run the executable. 
 
-
-- When editing in QGIS, it is advised to first convert to ESRI Shapefile.
-- Copy the sectors you want to edit to a new layer (important).
-- Make you changes.
-- When finished save your layer to GeoJSON.
-
-To convert GeoJSON to firboundaries.dat:
-1. Paste firboundaries.geojson you created in /output/
-2. Run export.py
-3. enter filename for input file (default is firboundaries.geojson)
-3. firboundaries.dat created in /export/
-
-- Make sure to only update/change the sectors you edited.
+To pack as executable using pyinstaller execute: </br> 
+```pyinstaller --onefile --windowed --icon=vattech.ico main.py```
