+# OONI Pipeline v5
+
+This it the fifth major iteration of the OONI Data Pipeline.
+
+For historical context, these are the major revisions:
+* `v0` - The "pipeline" is basically just writing the RAW json files into a public `www` directory. Used until ~2013
+* `v1` - OONI Pipeline based on custom CLI scripts using mongodb as a backend. Used until ~2015.
+* `v2` - OONI Pipeline based on [luigi](https://luigi.readthedocs.io/en/stable/). Used until ~2017.
+* `v3` - OONI Pipeline based on [airflow](https://airflow.apache.org/). Used until ~2020.
+* `v4` - OONI Pipeline basedon custom script and systemd units (aka fastpath). Currently in use in production.
+* `v5` - Next generation OONI Pipeline. What this readme is relevant to. Expected to become in production by Q4 2024.
+
+## Setup
+
+In order to run the pipeline you should setup the following dependencies:
+* [Temporal for python](https://learn.temporal.io/getting_started/python/dev_environment/)
+* [Clickhouse](https://clickhouse.com/docs/en/install)
+* [hatch](https://hatch.pypa.io/1.9/install/)
+
+
+### Quick start
+
+Start temporal dev server:
+```
+temporal server start-dev
+```
+
+Start clickhouse server:
+```
+mkdir -p clickhouse-data
+clickhouse server
+```
+
+You can then start the desired workflow, for example to create signal observations for the US:
+```
+hatch run oonipipeline mkobs --probe-cc US --test-name signal --start-day 2024-01-01 --end-day 2024-01-02
+```
+
+Monitor the workflow executing by accessing: http://localhost:8233/
