-# cppurl
 
-C++ libcurl framework
\ No newline at end of file
+# Rest client library, using libcurl
+
+A small framework for simple client-side REST API requests for C++. It uses libcurl. It got its name from a play on the words curl and cpp.
+
+## Features
+
+- Object oriented
+- Adjustable headers
+- Configurable user agent
+- Adjustable timeout
+- Native C++ containers: map, string
+- QA object
+- Curl and HTTP code status
+- It is possible to turn off certificate validation
+- A configurable version of the HTTP protocol
+
+## Installation
+
+Just download the latest release and unzip it into your project. You can turn it on with:
+
+```
+#include "cppurl/lib/cppurl.hpp"
+using namespace marcelb;
+```
+
+## Usage
+
+```c++
+// init, and sets
+Curl rest;
+string header_value = "3849f438uf9uedu8ejweoijwejd09230";
+rest.header("API", header_value).timeout(700)
+    .httpv(HTTP2).sslverifyoff();
+// execute and print
+cout << rest.get("https://reqres.in/api/users/2") << endl << 
+    "Curl status " << rest.curlStatus << endl << 
+    "HTTP status " << rest.httpStatus << endl;
+
+for (auto header : rest.responseHeader) {
+    cout << header.first << " " << header.second << endl;
+}
+
