 Because building ArduPilot is a bit complicated, I've written a short script that uses Docker to build AP in a controlled environment.

+If you have a parameter dump from QGroundControl, I wrote a small script that will convert it to a Mission Planner compatible file.
+
+Just save this script somewhere as `convert_qgc_params` and run it as `./convert_qgc_params <qgc params> <output file>`:
+
+```py
+#!/usr/bin/env python3
+import sys
+from decimal import Decimal
+
+
+def format_float(f):
+    return "{0:f}".format(Decimal(f).quantize(Decimal("1.0000000")).normalize())
+
+
+def main(infile, outfile):
+    with open(infile) as ins:
+        inputs = ins.read()
+
+    lines = []
+    for line in inputs.split("\n"):
+        if not line or line.startswith("#"):
+            continue
+        vehicle_id, component_id, name, value, type = line.split("\t")
+        v = value
+        if type == "9":
+            v = format_float(float(value))
+        lines.append(f"{name},{v}\n")
+
+    with open(outfile, "wt") as outs:
+        outs.writelines(lines)

+
+if __name__ == "__main__":
