+# InfluxDB to Bigquery import job
+
+This job collects AMP data from Influxdb and puts them into BQ.
+
+For more information on see https://mozilla-hub.atlassian.net/browse/RS-683
+
+## Usage
+
+This script is intended to be run in a docker container.
+Build the docker image with:
+
+```sh
+podman build -t influxdb-to-bigquery .
+```
+
+To run locally, install dependencies with (in jobs/influxdb-to-bigquery):
+
+```sh
+cd ..
+pip install -r requirements.txt
+```
+
+Run the script with (needs gcloud auth):
+
+```sh
+python3 influxdb_to_bigquery/main.py "--bq_project_id"=test_bq_project "--bq_dataset_id"=test_bq_dataset "--bq_table_id"=test_bq_table "--influxdb_measurement"=test_influx_measurement "--influxdb_username"=test_influx_un "--influxdb_password"=test_influx_pwd "--influxdb_host"=test_influx_host --date=test_date
+```
+
+## Development
+
+Run tests with:
+
+```sh
+pytest
+```
+
+`flake8` and `black` are included for code linting and formatting:
+
+```sh
+pytest --black --flake8
+```
+
+or
+
+```sh
+flake8 python_template_job/ tests/
+black --diff python_template_job/ tests/
+```
