+Contributing guidelines
+=======================
+
+### Git workflow
+
+* We use git-flow - create a feature branch from `develop`, e.g. `feature/new-feature`
+* Pull requests must contain a succinct, clear summary of what the user need is driving this feature change
+* Ensure your branch contains logical atomic commits before sending a pull request - follow the [alphagov Git styleguide](https://github.com/alphagov/styleguides/blob/master/git.md)
+* You may rebase your branch after feedback if it's to include relevant updates from the develop branch. We prefer a rebase here to a merge commit as we prefer a clean and straight history on develop with discrete merge commits for features

 # dp-search-reindex-tracker
 dp-search-reindex-tracker tracks a search reindex job
+
+### Getting started
+
+* Run `make debug`
+
+The service runs in the background consuming messages from Kafka.
+An example event can be created using the helper script, `make produce`.
+
+### Dependencies
+
+* Requires running…
+  * [kafka](https://github.com/ONSdigital/dp/blob/main/guides/INSTALLING.md#prerequisites)
+* No further dependencies other than those defined in `go.mod`
+
+### Configuration
+
+| Environment variable         | Default                           | Description
+| ---------------------------- | --------------------------------- | -----------

+| GRACEFUL_SHUTDOWN_TIMEOUT    | 5s                                | The graceful shutdown timeout in seconds (`time.Duration` format)

+| KAFKA_ADDR                   | "localhost:9092"                  | The address of Kafka (accepts list)
+| KAFKA_OFFSET_OLDEST          | true                              | Start processing Kafka messages in order from the oldest in the queue
+| KAFKA_NUM_WORKERS            | 1                                 | The maximum number of parallel kafka consumers
+| KAFKA_SEC_PROTO              | _unset_                           | if set to `TLS`, kafka connections will use TLS ([kafka TLS doc])

+
+### Healthcheck
+
+ The `/health` endpoint returns the current status of the service. Dependent services are health checked on an interval defined by the `HEALTHCHECK_INTERVAL` environment variable.
+
+ On a development machine a request to the health check endpoint can be made by:
+
+ `curl localhost:8125/health`
