+# Transit Driver XP
+
+Native Win32 driver client targeting Windows XP-era systems.
+
+The client authenticates with `auth_api` at `192.168.68.66:5000`, then requests
+assigned weekly schedule templates from `transit_api` at
+`192.168.68.66:5001/driver/schedules/daily`.
+
+Schedules are assigned through `transit.shifts`; the client does not expect a
+`driver_id`, `bus_id`, or `weekdays` column on `transit.schedules`.
+
+## Build
+
+```bash
+make clean && make
+```
+
+## Distribution
+
+Build the installer with:
+
+```bash
+makensis installer.nsi
+```
+
+Distribute `TransitDriverXPSetup.exe`. It detects an existing installation,
+stops the previous client, and replaces it in the same directory.
