+# MBTiles Extractor
+
+### Usage
+
+1) Save convert.py into the same folder as your .mbtiles file
+2) Make sure python is installed
+3) In terminal, cd into that folder
+4) Run this:
+
+```python
+    python convert.py filename.mbtiles
+```
+
+5) If you prefer XYZ schema instead of TMS run this:
+
+```python
+    python convert.py filename.mbtiles XYZ
+```
+
+That's it! It should generate a folder called filename filled with PNGs that contain the data in the mbtiles archive.
