+## Installation
+
+### Npm
+```console
+npm install swagger-ui-loader --save-dev 
+```
+
+### Yarn
+```console
+yarn add swagger-ui-loader --dev 
+```
+
+## Usage
+Add a run script that executes `swagger-ui-loader`. Your `package.json` should look similar to this. Now just run `npm run swagger`.
+
+```json
+{
+	"name": "i-am-your-package🤖",
+	"scripts": {
+		"swagger": "swagger-ui-loader"
+	},
+	"devDependencies": {
+		"swagger-ui-loader": "^0.1.0"
+	}
+}
+```
+
+Be default it will search for `swagger.json`, `swagger.yml` or `swagger.yaml` on the root directory of the project and it will run a server on port `5466`.
+
+You can add a property `swagger` to `package.json` with the following properties:
+
+- `file`: The path on which the file with the swagger data is located.
+- `port`: The port on which you want the server to run.
+
+The `package.json` will look like this with those properties.
+```json
+{
+	"name": "i-am-your-package🤖",
+	"scripts": {
+		"swagger": "swagger-ui-loader"
+    },
+    "swagger": {
+        "file": "./docs/swagger.yml",
+        "port": 8888,
+    },
+	"devDependencies": {
+		"swagger-ui-loader": "^0.1.0"
+	}
+}
+```
+
+If you run `npm run swagger` it will search for the `swagger.yml` inside the `docs` directory and the server will run on port `8888`.
