Li Chess Development Notes

OK, Puzzle development is hard to setup! Here's how you do it: Get a local setup, and a user! Upload this puzzle document to the puzzle collection:

{
    "_id" : 61053,
    "gameId" : "khzYI5hN",
    "history" : "h7h6",
    "fen" : "8/1p3rkp/6p1/1b6/4PnPP/5P2/3Q4/6K1 b - - 0 38",
    "lines" : {
        "lj" : {
            "23" : {
                "jH" : {
                    "UM" : true
                }
            }
        }
    },
    "depth" : 2,
    "white" : true,
    "date" : ISODate("2017-07-31T21:19:03.859Z"),
    "perf" : {
        "gl" : {
            "r" : 1500.0,
            "d" : 350.0,
            "v" : 0.06
        },
        "nb" : 0
    },
    "vote" : {
        "up" : 2,
        "down" : 0,
        "nb" : 2,
        "ratio" : 100
    },
    "attempts" : 10,
    "mate" : false
}

It's important to note that the ID of that puzzle is a bit of a magic number, so it's important to keep it as is. The game that goes with it, upload this to the game5 collection:
