-**IntershipManager** - The whole lifecycle of internship agreements in one app !
+# IntershipManager
+The whole lifecycle of internship agreements in one app !
 
 This is the **REST API** connecting to the InternshipManager front end application to manage **CRUD** operations.
 
 ## Installation
 
+Built using [node](https://nodejs.org/en/)@v16.10.0 !
+
+### Setting up dependencies
+
+Use npm to download all the dependencies :
+
 ```bash
 $ npm install
 ```
 
+### Setting up your config file
+
 In `/src/config/`, make a copy of the file `config.template.json` and rename it to `config.json`. 
 Set the following field :
+
 ```json
 "server": {
   "port": 3001
 },
 ```
-You may replace `3001` by any port you wish to run the application on.
 
-### Initiating the database
+This is the port the server will run on.
+You may replace `3001` by any port you wish to run the server on.
 
-This server uses [Mongodb](https://www.mongodb.com/) for persistent data storage. To initiate the database, you must have an instance of mongo running. You may use the dockerfile located in `docker/` at the root of the project and run the command `docker-compose up -d` to create and run a mongo instance as a background task.

 In the `src/config/config.json`, set the following field :
+
 ```json
 "mongodb": {
   "uri": "mongodb://localhost:27017/internship-manager"
 }

 In the event you wish to run mongo on another port or use another collection, make sure to update the **uri** in the config file.

+
+```bash
+$ nest start --watch
