+# minipp
+
+A lightweight, header-only C++14 parser and writer for the mini config format.
+
+## Description
+minipp provides a convenient way to parse and write configuration files in the "mini" format. This format is characterized by its human-readable structure and nested sections, making it ideal for application configurations.
+
+## Features
+
+- **Parsing**: Extract values from existing mini configuration files.
+  - Supports strings, integers, floats, booleans, arrays, and nested sections.
+
+- **Writing**: Generate new mini configuration files.
+  - Create complex structures with nested sections and various data types.
+
+- **Single Header**: minipp is a single-header library, meaning you only need to include one file.
+
+## Usage
+
+To use minipp in your project:
+
+```cpp
+#define MINIPP_IMPLEMENTATION
+#include "minipp.hpp"
+```
+
+Then, you can use `minipp::MiniPPFile` to parse and write mini files throughout your code.
+
+### Example Usage
+
+```cpp
+#define MINIPP_IMPLEMENTATION
+#include "minipp.hpp"
+
+using namespace minipp;
+
+int main()
+{
+  // Make room for a result variable. 
+  EResult result;
+
+  MiniPPFile file;
+  result = file.Parse("test.mini");
+  auto& root = file.GetRoot();
+
+  MiniPPFile::Section* gameSection = nullptr;
+  result = root.GetSubSection("game", &gameSection);
+  MiniPPFile::Values::StringValue* nameValue = nullptr;
+  result = gameSection->GetValue("name", &nameValue);
+  MiniPPFile::Values::IntValue* yearValue = nullptr;
+  result = gameSection->GetValue("year", &yearValue);
+
+  // Get a sub-section (section of a section (stated in the MINI file with "[game.window]")
+  MiniPPFile::Section* windowSection = nullptr;
+  result = gameSection->GetSubSection("window", &windowSection);
+
+  MiniPPFile::Section* windowPlatformSection = nullptr;
+  // Get a sub-section by using the dot operator
+  result = gameSection->GetSubSection("window.platform", &windowPlatformSection);
+
+  MiniPPFile::Values::ArrayValue* pointsValue = nullptr;
+  // Retrieve an array by using the relative value path (the game section is a child of the root section)
+  result = root.GetValue("game.window.platform.targets", &pointsValue);
+
+  // Modify the "targets" array by adding a new value
+  pointsValue->GetValues().push_back(std::make_unique<MiniPPFile::Values::StringValue>("haiku"));
+
+  // Serialize the config
+  result = file.Write("test_out.mini");
+
+  return 0;
+}
+```
+
+## Getting Started
+
+1. **Include minipp**: Add the following line to your file:
+
+   ```cpp
+   #define MINIPP_IMPLEMENTATION
+   #include "minipp.hpp"
+   ```
+   Note, that you must define MINIPP_IMPLEMENTATION exactly once in your project!
+
+2. **Create a `MiniPPFile` object**:
+
+   ```cpp
+   MiniPPFile file;
+   EResult result = file.Parse("your-file.mini");
+   ```
+
+3. **Parse and access values**:
+
+   ```cpp
+    // Access sections
+    MiniPPFile::Section* gameSection = nullptr;
+    EResult result = root.GetSubSection("game", &gameSection);
+
+    // Access values
+    MiniPPFile::Values::StringValue* nameValue = nullptr;
+    result = gameSection->GetValue("name", &nameValue);
+
+    // Navigate nested sections
+
+    MiniPPFile::Section* windowSection = nullptr;
+    result = gameSection->GetSubSection("window", &windowSection);
+
+    // .. OR ..
+
+    MiniPPFile::Section* windowSection = nullptr;
+    result = root->GetSubSection("game.window", &windowSection);
+
+   ```
+   Note, that the root node cannot have values!
+   
+   Also, arrays are contained in an ArrayValue (container of multiple different Values (may also include other arrays))
+
+   ```cpp
+    // Handle arrays
+    MiniPPFile::Values::ArrayValue* pointsValue = nullptr;
+    result = root.GetValue("game.window.platform.points", &pointsValue);
+
+    // Modify the array values (or read them)
+    pointsValue->GetValues().push_back(std::make_unique<MiniPPFile::Values::StringValue>("haiku"));
+
+   ```
+5. **Write new files**:
+
+   ```cpp
+    result = file.Write("new-file.mini");
+   ```
+
+## Example
+
+An example mini file is contained in this [repository](test.mini). The full mini file format specilization can be found [here](https://github.com/ToyB-Chan/mini-file-format).
+
+## Installation
+
+1. Copy the contents of "minipp.hpp" to a new file in your project.
+2. #Include "minipp.hpp" after defining MINIPP_IMPLEMENTATION in one single cpp file.
+3. #Include "minipp.hpp" in any other desired files without the IMPLEMENTATION define!
