+# Postman Collection
 
-The [Postman](https://www.postman.com/) [collection](./collection.postman.json) is generated using [Portman](https://www.npmjs.com/package/@apideck/portman) tool from the [OpenApi Spec](../openapi/open_api_spec.yaml).
+You can find the latest Postman collection [here][postman-collection].
+For getting started quickly, you can also

-Steps to generate the new collection.
+## Auto-Generating the Postman Collection
 
-* Install portman [ [refer to github](https://github.com/apideck-libraries/portman) ]
+The [Postman collection][postman-collection] is generated using
+[`portman`][portman] tool from the [OpenAPI specification][openapi-spec].
+If you'd like to generate the collection from the OpenAPI specification, you can
+follow the below steps:
 
-    ```bash
+1. Install `portman`, refer to the instructions on
-    # Global install
+   [the repository][portman-repository]:
-    $ npm install -g @apideck/portman
-    ```
 
-* From the base directory, run
+   ```shell
+   npm install -g @apideck/portman
+   ```
 
-    ```bash
+2. From the root of the project directory, run the following command to generate
-    portman --cliOptionsFile postman/portman-cli.json
+   the Postman collection.
-    ```
+
+   ```shell
+   portman --cliOptionsFile postman/portman-cli.json
