+## What is it?
 
 OpenDroneMap is an open source toolkit for processing aerial drone imagery. Typical drones use simple point-and-shoot cameras, so the images from drones, while from a different perspective, are similar to any pictures taken from point-and-shoot cameras, i.e. non-metric imagery. OpenDroneMap turns those simple images into three dimensional geographic data that can be used in combination with other geographic datasets.

-#### Running OpenDroneMap
+### Run OpenDroneMap
 
 First you need a set of images, which may or may not be georeferenced. There are two ways OpenDroneMap can understand geographic coordinates. First, the images can be geotagged in their EXIF data. This is the default. Alternatively, you can create a GCP file, [a process detailed here](https://github.com/OpenDroneMap/OpenDroneMap/wiki/2.-Running-OpenDroneMap#running-odm-with-ground-control)
 
 Create a project folder and places your images in an "images" directory:
 
-
     |-- /path/to/project/
         |-- images/
             |-- img-1234.jpg
