-I use this script with windows set up like this in code-server.
+---

+**This is a very simple wrapper for curl that I use with VSCode (code-server) to make HTTP requests - like Postman but super simple.**
+
+VSCode is not required to run this script, I use it as a GUI.
 
 # Files
 This script uses separate files for various request options. Create these files in the same directory as `curl.sh`.
 
 ## `params.txt`
-URL search parameters.
+URL search parameters. (Leading "?" is optional)
+```
+foo=bar&hello=world
+```
 
-## `paylaod.json`
+## `payload.json`
 JSON request body that will be sent with all requests (except `GET`).
+```json
+{
+    "request_body_parameter": "request_body_value"
+}
+```
 
-## `key.txt`
-[HTTP Authentication Bearer Token](https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication)
+## `headers.json`
+Key-value JSON object of optional request headers.
+```json
+{
+    "X-Header-Name": "Header value"
+}
+```
 
 ## `disable_peer_validation`
 Optional empty file that when present will disable SSL peer validation - for self-signed certificates etc.
