+# Quickstart (Windows)
+
+## 1) Install Go
+Install a recent Go version and ensure `go version` works in PowerShell.
+
+## 2) Build the parser
+Open PowerShell in the project folder and run:
+
+```powershell
+go mod download
+go build -o acars_parser.exe .\cmd\acars_parser
+```
+
+## 3) Run extract (CLI)
+```powershell
+.\acars_parser.exe extract -input messages.jsonl -output out.json -pretty -all
+```
+
+## 4) Run GUI wrapper
+```powershell
+python .\gui\acars_parser_gui.py
+```
+
+## 5) HTML viewer waypoint lookup
+
+The standalone viewer [gui/acars_viewer_fast_kv_map_v8.html](gui/acars_viewer_fast_kv_map_v8.html) can resolve named FPN and PWI route waypoints through [gui/Waypoints.txt](gui/Waypoints.txt), so those points can be drawn on the map even when the JSON only contains waypoint names.
+
+The viewer also supports filtering rows that have a Flight value and sorting the Summary / Details column by the amount of message content, which is useful for surfacing the densest ACARS messages first.
+
+If the viewer is opened via a local `file:` URL, some browsers block automatic loading of sibling files. In that case, use the `Load Waypoints` control in the viewer and select `gui/Waypoints.txt` manually.
+
+Notes:
+- Input must be JSONL (one JSON object per line) matching either:
+  - `internal/acars.Message`, or
+  - NATS wrapper (`internal/acars.NATSWrapper`) with `message{...}` inside.
