+# udacity-c2-basic-server
+
+This is a simple node-express server to explore and understand the Request-Response pattern.
+
+***
+## Getting Setup
+
+### Installing project dependencies
+
+This project uses NPM to manage software dependencies. NPM Relies on the package.json file located in the root of this repository. After cloning, open your terminal and run:
+```bash
+npm install
+```
+>_tip_: **npm i** is shorthand for **npm install**
+
+### Installing useful tools
+#### 1. [Postbird](https://github.com/paxa/postbird)
+Postbird is a useful client GUI (graphical user interface) to interact with our provisioned Postgres database. We can establish a remote connection and complete actions like viewing data and changing schema (tables, columns, ect).
+
+#### 2. [Postman](https://www.getpostman.com/downloads/)
+Postman is a useful tool to issue and save requests. Postman can create GET, PUT, POST, etc. requests complete with bodies. It can also be used to test endpoints automatically. We've included a collection (`./udacity-c2-restapi.postman_collection.json `) which contains example requsts.
+
+***
+
+## Running the Server Locally
+To run the server locally in developer mode, open terminal and run:
+```bash
+npm run dev
+```
+
+Developer mode runs off the TypeScript source. Any saves will reset the server and run the latest version of the codebase. 
+
+***
