+### Updating GraphQL schema
+
+- Modify `server/graph/schema.graphqls` file
+- Run `make generate-graphql` this will update the models and required methods
+- If a new mutation or query is added
+  - Write the implementation for the new resolver in `server/resolvers/NEW_RESOLVER.GO`
+  - Update `server/graph/schema.resolvers.go` with the new resolver method
+
+### Adding support for new database
+
+- Run `make generate-db-template dbname=NEW_DB_NAME`
+  eg `make generate-db-template dbname=dynamodb`
+
+This command will generate a folder in server/db/providers/ with name specified in the above command.
+One will have to implement methods present in that folder.
+
+> Note: Connection for database and schema changes are written in `server/db/providers/DB_NAME/provider.go` > `NewProvider` method is called for any given db based on the env variables present.
