+# Gonk Python Tools Bundle
+
+Unzip and install the bundle.
+
+```sh
+unzip gonk_bundle.zip
+cd gonk_bundle
+./setup.sh
+```
+
+## Flash a Gonk for the first time:
+
+```sh
+. ./python-venv/bin/activate
+gonk-flash
+```
+
+or without activating the Python virtualenv:
+
+```sh
+./python-venv/bin/gonk-flash
+```
+
+## Log ADC measurements
+
+### Logging
+
+By default two log files are created:
+
+- Host log messages are set to: `--logfile gonk-logs.txt`
+- Device (logs from Gonk) are set to: `--device-logfile gonk-device-logs.txt`
+
+You can add ADC json output with the `--json-logfile gonk-device-logs.json`
+option.
+
+That will produce a json lines file with each line corresponding to one ADC
+measurement event. For example:
+
+```
+{
+  "message": "host_time: 20240507 12:47:41.308278 size: 40 delta_microseconds: 204 vbus: 3,2,3,2,2 vshunt: 0,0,0,69,0",
+  "levelno": 20,

+  ],
+  "time": "1715111261.308351",
+  "time_string": "2024-05-07T12:47:41",

+    "vshunt_values": "[3, 2, 3, 2, 2]"
+  }
+}
+```
+
+### Start Logging ADC Measurements
+
+```sh
+./python-venv/bin/gonk --log-to-stderr --bitstream-file DEFAULT
+```
+
+This will provision the FPGA and begin logging ADC measurements.
