 # Backend [Places-Microservice-Server]
 [![Build Status](https://travis-ci.com/climatetree/places-microservice.svg?branch=develop)](https://travis-ci.com/climatetree/places-microservice)
 [![Quality Gate Status](https://sonarcloud.io/api/project_badges/measure?project=com.climatetree%3Aplaces-microservice&metric=alert_status)](https://sonarcloud.io/dashboard?id=com.climatetree%3Aplaces-microservice)
+
+# Microservice Architecture
+## Repo Structure
+This repository holds the source code for the backend services for locations/places included included the 
+climateTree.wiki web application. This application was built using Java, Maven, and Spring Boot.
+This repo contains the following important folders:
+- Controller
+    - Hosts the API endpoints
+- Dao
+    - Provides queries that can be called on the connected database.
+    - All queries return a GeoJson object string.
+- Services
+    - Intermediary class between the Controller and the Dao that performs additional data processing 
+      steps.
+
+The Model and DTO folders are not currently in use, but were kept for archiving purposes. 
+
+## API Endpoints
+It is important to note that only 1 of the 4 APIs is currently being used in the climateTree.wiki project. The
+only API that is being used is `/api/v1/places/{name}`. This is being used by the front end to retrieve the names
+of places that contain the given `name`. All other APIs have been transition to GeoServer. The GeoServer repository 
+can be viewed [here](https://github.com/climatetree/geoserver-docker).
+
+The endpoints that are defined in the Controller can be viewed [here on Postman](https://documenter.getpostman.com/view/10295047/Szf55VXU?version=latest)
+
+## Database
+This application directly connects to the ClimateTree project's Places Database that is currently hosted
+on Azure. Connection strings are provided as environment variables to the `application.properties` configuration. The
+database schema can be seen [here](https://tinyurl.com/yaa3rfp3).
