 # Integrating MapRoulette
 
+## Importing points

 [MapRoulette](https://www.maproulette.org/) is a website which has challenges. A challenge is a collection of _microtasks_, i.e. mapping tasks which can be solved in a few minutes.
 
 A perfect example of this is to setup such a challenge to e.g. import new points.

 (Another approach to set up a guided import is to create a map note for every point with the [import helper](https://mapcomplete.osm.be/import_helper). This however litters the map notes and will upset mappers if used with to much points. However, this flow is easier to setup as no changes to theme files are needed, nor is a maproulette-account needed)
 
+## Preparing the data
+
+Convert your source data into a geojson. Use *`tags`* as field where all the OSM-properties should go. Make sure to include all tags there.
+
+Hint: MapRoulette has a button 'rebuild task', where you can first 'remove all incomplete tasks'. This is perfect to start over in case of small data errors.

 ## The API
