+
 
 ## Getting started
+
 There are several things that need to be completed to properly setup and secure the API.
-1. Auth0 API configuration
+This API uses OpenAPI Specification 3.0. After configuring the API, launch the software
+and navigate your browser to https://localhost:5001/swagger to view the endpoints.
+
+1. JWT Information
 2. API filesystem paths
 3. Database connection string
 4. Migrations
 
-### Auth0 API configuration
 
-Securing Icarus is required, preventing the API from being publicly accessible. To do so, create an Auth0 account (it's free), for the sake of this section of the documentation, I will not go over how to create an Auth0 account. Once created, create a tentant and proceed to create an API
+### JWT Information
-<h1 align=center>
-    <img src="Images/Configuration/create_api.png" width=100%>
-</h1>
 
-Create the API and enter an approrpiate name and identified. For the identified, append **api** like in the example
+Configure JWT information. Notably the Secret
-<h1 align="center">
-    <img src="Images/Configuration/enter_api_info.png" width=100%>
-</h1>
-Replace [domain] with the domain name of the created tenant. This can be found in the Default App from the Application menu. Replace [identifier] with the identifer root name in the appsettings environment file. Not the friendly name but the root name of the identifier, omitting the http protocol and the *api* path.
 
 ```Json
-  "Auth0": {
+  "JWT": {
-	  "Domain": "[domain].auth0.com", 
+    "Issuer": "IcarusAPI",
-	  "ApiIdentifier": "https://[identifier]/api"
+    "Audience": "IcarusAPIClient",
+    "Secret": "Manaiswhatyouthinkitis",
+    "Subject": "Authorization"
   },
 ```
 
-For the sake of this section, I will not go over configuring the API to accept the signing algorithm since it has already been configured in the [Startip](Startup.cs).cs file. Click on permissions to create the permissions for the API.

 ### API filesystem paths
 
 For the purposes of properly uploading, downloading, updating, deleting, and streaming songs the API filesystem paths must be configured. What is meant by this is that the `RootMusicPath` directory where all music will be stored must exist as well as the `ArchivePath` and `TemporaryMusicPath` paths. An example on a Linux system:

 ### Database connection string
 
 In order for Database functionality to be operable, there must be a valid connection string and credentials with appropriate permissions. **At the moment there is only support for MySQL**. Depending on your environment `Release` or `Debug` you will need to edit the appsettings.json or appsettings.Development.json accordingly. An example of the fields to change are below:

 * Database - The database name
 * Uid - Username
