 There are a couple of points to note:
-* The value of MICROSERVICE should be the name of a given microservice's subdirectory in this repo. As of Oct-6-2023, the available subdirectories are: `config-service`, `elisa-logbook`, `ers-dbwriter`, `ers-protobuf-dbwriter`, `opmon-dbwriter`, `runnumber-rest` and `runregistry-rest`. 
+* The value of MICROSERVICE should be the name of a given microservice's subdirectory in this repo. As of Jul-25-2024, the available subdirectories are: `config-service`, `elisa-logbook`, `ers-dbwriter`, `ers-protobuf-dbwriter`, `opmon-dbwriter` (now deprecated), `opmon-protobuf-dbwriter`, `runnumber-rest` and `runregistry-rest`. 
 * Most microservices require additional environment variables to be set, which can be passed using the usual docker syntax: `-e VARIABLE_NAME=<variable value>`
 * If you don't know what these additional environment variables are, you can just run the `docker` command as above without setting them; the container will exit out almost immediately but only after telling you what variables are missing
 * The microservices image tag will be `microservices:<name-of-branch>` or `microservices:<version-tag>`, i.e. `microservices:develop`.

+`dbwriter.py` is the script responsible for taking the opmon messages via the OpMonSubscriber
+and writing to an InfluxDB database so that the data can be displayed in a
+grafana dashboard. To run it manually do:
+```python dbwriter.py [options]```
+
+
+# Running locally
+The script can be run locally which can be useful to debug or start up quickly. After setting up a working area and cloning this repo, run:
+```
+python3 dbwriter.py
+```
+Passing the appropriate variables. 
+As this script requires opmonlibs and kafkaopmon, it has to be launched by a developing envirnoment.
+It can run at the same time locally and in kubernetes.
