+Giants Map Objects Extractor
+============================
+
+This tool is used to get extract in a map. It outputs the objects model and coords and doesn't do anything else yet.
+
+How it works
+------------
+
+Basically maps are just a zip file that contains a terrain file (.gti) and a meta file (.bin) which stores objects on the map.
+
+Objects in this file are stored using the following format:
+```
+...
+2a -> static byte which indicate the start of an object definition
+model -> 4 bytes long value to indicate the model of the object
+x -> 4 bytes float value
+y -> 4 bytes float value
+z -> 4 bytes float value
+angle -> 4 bytes float value
+...
+```
+
+Usage
+----
+
+```
+C:\Projects\gck-map-extract-objects> python .\extract.py
+usage: extract.py [-h] map_file
+extract.py: error: the following arguments are required: map_file
+```
+
+Example
+-------
+
 ```
