 * Set OTB application folder. This is location of your OTB applications. ``<OTB_FOLDER>/lib/otb/applications``

-Using the processing toolbox (for QGIS < 3.0)
----------------------------------------------
-
-In older QGIS version (3.0 or before), OTB applications are available from QGIS.
-Use them from the processing toolbox, which is accessible under `Processing
--> ToolBox`. Switch to “advanced interface” in the bottom of the
-application widget and OTB applications will be there.

-On some versions of QGIS, if an existing OTB installation is found, the

+Troubleshoot
+------------
+As of QGIS 3.8 the otb plugin is in the core. It might get messy if you have a previously installed plugin. Try to remove the old plugin before launching QGIS.
