Had some difficulties finding a shapefile for the City of Kigali. I have uploaded the country's shapefiles which is broken down into district boundaries.Please advise other tools to get a reliable shapefile.

Hey Tichayana,
Have you learned how to convert Open Street Map (OSM) relations to shapefiles?
I found https://www.openstreetmap.org/node/60485579 for Kigali, as you probably did too. At the bottom left of this site, it points you to "Relation Kigali City (1708283) (as admin_centre) ", so here is where you see the city outline: https://www.openstreetmap.org/relation/1708283
Does that help you? Can you move on with this?

Hey Caroline. Thank you it was helpful
