+
+[github-actions-shield]: https://github.com/rayokota/jsonata-cpp/actions/workflows/cmake-multi-platform.yml/badge.svg?branch=master
+
+C++ implementation of JSONata.
+
+This is a C++ port of the  [JSONata reference implementation](https://github.com/jsonata-js/jsonata), 
+and also borrows from the [Dashjoin Java port](https://github.com/dashjoin/jsonata-java).
+
+This implementation supports 100% of the language features of JSONata, using [nlohmann_json](https://github.com/nlohmann/json).
+The JSONata documentation can be found [here](https://jsonata.org).
+
+
+## Installation
+
+Installation uses CMake as follows:
+
+```
+include(FetchContent)
+
+FetchContent_Declare(
+    jsonata
+    URL https://github.com/rayokota/jsonata-cpp/archive/refs/tags/v0.1.0.zip
+    URL_HASH SHA256=3ee1798f28a29d36ebbb273853979926716a384e4d491a6bd408e1f6de51760d  # Optional
+)
+FetchContent_MakeAvailable(jsonata)
+
+# Use the library
+target_link_libraries(your_target jsonata::jsonata)
+```
+
+## Getting Started
+
+A very simple start:
+
+```
+#include <iostream>
+#include <jsonata/Jsonata.h>
+#include <nlohmann/json.hpp>
+
+int main() {
+    // Create the data equivalent to Python
+    auto data = nlohmann::ordered_json::parse(R"({
+        "example": [
+            {"value": 4}, 
+            {"value": 7}, 
+            {"value": 13}
+        ]
+    })");
+
+    // Create the JSONata expression
+    jsonata::Jsonata expr("$sum(example.value)");
+    
+    // Evaluate the expression with the data
+    auto result = expr.evaluate(data);
+    
+    // Print the result
+    std::cout << "Result: " << result << std::endl;
+    
+    return 0;
+}
+```
+
+## Running Tests
+
+This project uses the repository of the reference implementation as a submodule. This allows referencing the current version of the unit tests. To clone this repository, run:
+
+```
+git clone --recurse-submodules https://github.com/rayokota/jsonata-cpp
+```
+
+To build and run the unit tests:
+
+```
+cmake -DJSONATA_BUILD_TESTS=ON -S . -B build
+cmake --build build
+cd build && ctest
+```
