+## Code Style
+
+We adhere to the standards given in the [Google Style guide](https://google.github.io/styleguide/pyguide.html)
+For Linting, `PyLint` is used.
+
+## Modules to be used
+- All services are written using [FastAPI](https://fastapi.tiangolo.com/)
+- [Pymongo](https://pymongo.readthedocs.io/en/stable/) is preferred as mongo client. Should there be a need for Async, Motor can be used.
+- [Mongo Utility](https://gitlab-pm.knowledgelens.com/KnowledgeLens/Products/iLens-2.0/platform-general/-/blob/master/mongo_util/mongo_util.py) is available for all UnifyTwin projects. It is strongly advised to use the util as it takes care of various standards we follow in UnifyTwin (DB split, security, etc).
