+![ElastiCpp-Debug](https://github.com/bastianhjaeger/elasticpp/workflows/ElastiCpp-Debug/badge.svg?branch=master)
+
+Interface to manipulate elasticsearch by REST API from c++. 
+
+# Installation
+```bash
+git clone [email protected]:bastianhjaeger/elasticpp.git
+cd elasticpp
+mkdir build && cd build
+cmake -DCMAKE_BUILD_TYPE=Release ..
+make -j8
+sudo make install
+```
+
+# Usage
+
+## plain functions
+```c++
+#include <elasticpp/elasticpp.h>
+
+const bool singleCall = true;
+const bool verbose = true;
+
+const std::string sResponse 
+    = elastic_cpp("http://localhost:9200/test", "", "", PUT, singleCall, verbose);
+const json jResponse 
+    = elastic_cpp("http://localhost:9200/test", "", json(), PUT);
+```
+
+## class implementation
+```c++
+#include <elasticpp/ElastiCpp.h>
+
+const int verbose = 0;
+const int shards = 1;
+const int replicas = 1;
+const std::string url = "test_index";
+
+ElastiCpp ec("http://localhost:9200/", "user:password");
+
+bool success = ec.createIndex(url, shards, replicas, verbose);
+
+const json response = ec.getIndex(url, verbose);
+std::cout << "response: " << response.dump(3) << std::endl;
+
+success = ec.deleteIndex(url, verbose);
+
+// or any randon message/query
+const json response2 = ec.send("index_*/_search", R"({"query": {"match_all": {}}})");
+```
