Adding custom processing provider into QGIS

Question

I am trying to add a new processing algorithm provider into QGIS 2.18. In the picture below there are GDAL/OGR, GRASS GIS, etc. I want to add a provider called My Provider.

So I read the doc here: https://docs.qgis.org/2.18/en/docs/pyqgis_developer_cookbook/processing.html and saw:

enter image description here

So I followed:

enter image description here enter image description here enter image description here

Then I reopened QGIS and installed the plugin, but no new provider appears. I read this thread: How to see the 'example provider' in processing toolbox of QGIS?. But this looks like this is for version 2.8, my exampleprovider is located in QGIS_2_18\apps\qgis\python\plugins\processing\algs\exampleprovider and I dont see which import is pointing to the wrong file.

What should I modify to make my provider appear in the processing toolbox?

• Joseph: To clarify, are you wanting to add a new provider from your plugin?
