+## Bangkok Transit
+
+Scrape data from [transitbangkok.com](http://www.transitbangkok.com/) and put it online. Adding some tiny snippet for querying commute instruction.
+
+### Usage
+
+```python
+import transit
+stations = transit.read_stations('data/stations.csv')
+route_descriptions = transit.get_commute_instruction('บางรัก', 'สีลม', stations) # return route instruction
+```
+
+**Output**
+
+```python
+{'query_link': 'http://www.transitbangkok.com/showBestRoute.php?from=Bang+Rak+Market&to=Si+Lom&originSelected=false&destinationSelected=false&lang=en',
+ 'route_descrtions':
+    [{'action': 'Walk by foot',
+      'lines': [],
+      'to': 'Sathorn/Saphan Taksin'},
+     {'action': 'Public Transport',
+      'lines': ['BTS - Silom Line', '76', '163', '164', '172', '177', '504', '544', '547'],
+      'to': 'Sala Daeng'},
+     {'action': 'Walk by foot',
+      'lines': [],
+      'to': 'Si Lom'}],
+ 'station_end':
+    {'station_link': 'http://www.transitbangkok.com/stations/Bangkok%20Bus/Si%20Lom',
+     'station_name': 'Si Lom',
+     'station_thai_name': 'สีลม'},
+  'station_start':
+    {'station_link': 'http://www.transitbangkok.com/stations/Bangkok%20Bus/Bang%20Rak%20Market',
+     'station_name': 'Bang Rak Market',
+     'station_thai_name': 'ตลาดบางรัก'}
+}
+```
+
+The output (if both stations start and end match with their database)
+will be list of instructions to go to the destination.
