index.html not appearing

Dunno why. No errors, but there's no index.html anywhere.

Most content of the "viewer" directory is static, it contains index.html, MinedMap.js and the Leaflet library, as found in the Git repo or the released viewer ZIP. The actual MinedMap generator only creates the data files (map tiles + JSON metadata) to be used by the viewer.

So you would unpack the viewer somewhere where your webserver finds it, and then run MinedMap as

</path/to/MinedMap> </path/to/my/minecraft/savegame> </path/to/the/viewer>/data

(that is, the final /data must be part of the passed path, so the data is generated in the data subdir of the viewer directory.
