Isochrone developer guide

I was wondering if there is an updated version of the isochrone developer guide (https://github.com/graphhopper/graphhopper/blob/1.0-pre38/docs/isochrone/java.md) as this references an isochrone class which does not appear in the latest tag?

I appreciate the IsochroneResource class is more comprehensive, but I was hoping for a simpler starter before having to expand my understanding of the wider architecture

Any help would be appreciated in getting me started

These docs are indeed outdated, this is tracked now via: https://github.com/graphhopper/graphhopper/issues/1987

For now take a look at the ShortestPathTree class (or use the 0.13 release).

Thank you I’ll take a look
