+### 4. Arguments
+Maps are saved in maps directory with json format.\
+It's two dimensional array of types of fields. \
+Example: 
+```json
+[
+  ["Corn", "Sunflower","Clay"],
+  ["Clay", "Soil","Clay"],
+  ["Sunflower", "Soil","Corn"]

+#####4.1 Save generated map:
+```bash
+python main.py --save-map

+Map will be saved in maps directory. 
+Generated filename: map-uuid

+#####4.2 Load map
+```bash
+python main.py --load-map=name_of_map
+```
+Map must be in the maps directory with json extension.
