+Can I process two or more orthophoto GeoTIFFs to stitch them together?
 ----------------------------------------------------------------------
 
 No. ODM is a photogrammetric pipeline and orthophotos do not have the necessary camera information since the images have already been orthorectified. You can use another program such as `Hugin <http://hugin.sourceforge.net/>`_ to do that.
 
 The software is not using all of my CPU cores / memory / GPU all of the times. Is it normal?
----------------------------------------------------------------------------
+--------------------------------------------------------------------------------------------
 
 Yes. The software tries to use all available resources, when possible, but not always. It's normal to see 10-15% resource utilization at several moments during processing.
 
 If I use the native version of the software, how can I allocate more resources for processing?
 ----------------------------------------------------------------------------------------------
 
-No need; the native (non-docker) version of the software alredy uses all available resources.
+No need; the native (non-docker) version of the software already uses all available resources.

 3. Configure a swapfile. In both Windows and Linux you will need preferably a fast SSD or an NVME drive, and the computing process will be still a LOT slower.
 
   - If you are using Windows with `Docker+WSL2 <https://docs.docker.com/desktop/windows/wsl/>`_ you can add two rows in your .wslconfig file so that Docker will use a swapfile.
