-# NOSTR Core Library - Automatic Versioning System
-
-## Overview
-
-The NOSTR Core Library now features an automatic version increment system that automatically increments the patch version (e.g., v0.2.0 → v0.2.1) with each build. This ensures consistent versioning and traceability across builds.
-
-## How It Works
-
-### Version Format
-The library uses semantic versioning with the format: `vMAJOR.MINOR.PATCH`
-
- **MAJOR**: Incremented for breaking changes (manual)
- **MINOR**: Incremented for new features (manual)  
- **PATCH**: Incremented automatically with each build
-
-### Automatic Increment Process
-
-1. **Version Detection**: The build system scans all git tags matching `v*.*.*` pattern
-2. **Highest Version**: Uses `sort -V` to find the numerically highest version (not chronologically latest)
-3. **Patch Increment**: Increments the patch number by 1
-4. **Git Tag Creation**: Creates a new git tag for the incremented version
-5. **File Generation**: Generates `nostr_core/version.h` and `nostr_core/version.c` with build metadata
-
-### Generated Files
-
-The system automatically generates two files during each build:
-
-#### `nostr_core/version.h`
-```c
-#define VERSION_MAJOR 0
-#define VERSION_MINOR 2  
-#define VERSION_PATCH 1
-#define VERSION_STRING "0.2.1"
-#define VERSION_TAG "v0.2.1"
-
-#define BUILD_DATE "2025-08-09"
-#define BUILD_TIME "10:42:45"
-#define BUILD_TIMESTAMP "2025-08-09 10:42:45"
-
-#define GIT_HASH "ca6b475"
-#define GIT_BRANCH "master"
-
-// API functions
-const char* nostr_core_get_version(void);
-const char* nostr_core_get_version_full(void);
-const char* nostr_core_get_build_info(void);
-```
-
-#### `nostr_core/version.c`
-Contains the implementation of the version API functions.
-
-## Usage
-
-### Building with Auto-Versioning
-
-All major build targets automatically increment the version:
-
-```bash
-# Build static library (increments version)
-./build.sh lib
-
-# Build shared library (increments version)
-./build.sh shared
-
-# Build all libraries (increments version)
-./build.sh all
-
-# Build examples (increments version)
-./build.sh examples
-
-# Install to system (increments version)
-./build.sh install
-```
-
-### Non-Versioned Builds
-
-Some targets do not increment versions:
-
-```bash
-# Clean build artifacts (no version increment)
-./build.sh clean
-
-# Run tests (no version increment)
-./build.sh test
-```
-
-### Using Version Information in Code
-
-```c
-#include "version.h"
-
-// Get version string
-printf("Version: %s\n", nostr_core_get_version());
-
-// Get full version with timestamp and commit
-printf("Full: %s\n", nostr_core_get_version_full());
-
-// Get detailed build information  
-printf("Build: %s\n", nostr_core_get_build_info());
-
-// Use version macros
-#if VERSION_MAJOR >= 1
-    // Use new API
-#else
-    // Use legacy API
-#endif
-```
-
-### Testing Version System
-
-A version test example is provided:
-
-```bash
-# Build and run version test
-gcc -I. -Inostr_core examples/version_test.c -o examples/version_test ./libnostr_core.a ./secp256k1/.libs/libsecp256k1.a -lm
-./examples/version_test
-```
-
-## Version History Tracking
-
-### View All Versions
-```bash
-# List all version tags
-git tag --list
-
-# View version history
-git log --oneline --decorate --graph
-```
-
-### Current Version
-```bash
-# Check current version
-cat VERSION
-
-# Or check the latest git tag
-git describe --tags --abbrev=0
-```
-
-## Manual Version Management
-
-### Major/Minor Version Bumps
-
-For major or minor version changes, manually create the appropriate tag:
-
-```bash
-# For a minor version bump (new features)
-git tag v0.3.0
-
-# For a major version bump (breaking changes)  
-git tag v1.0.0
-```
-
-The next build will automatically increment from the new base version.
-
-### Resetting Version
-
-To reset or fix version numbering:
-
-```bash
-# Delete incorrect tags (if needed)
-git tag -d v0.2.1
-git push origin --delete v0.2.1
-
-# Create correct base version
-git tag v0.2.0
-
-# Next build will create v0.2.1
-```
-
-## Integration Notes
-
-### Makefile Integration
- The `version.c` file is automatically included in `LIB_SOURCES`
- Version files are compiled and linked with the library
- Clean targets remove generated version object files
-
-### Git Integration
- Version files (`version.h`, `version.c`) are excluded from git via `.gitignore`
- Only version tags and the `VERSION` file are tracked
- Build system works in any git repository with version tags
-
-### Build System Integration
- Version increment is integrated directly into `build.sh`
- No separate scripts or external dependencies required
- Self-contained and portable across systems
-
-## Example Output
-
-When building, you'll see output like:
-
-```
-[INFO] Incrementing version...
-[INFO] Current version: v0.2.0
-[INFO] New version: v0.2.1
-[SUCCESS] Created new version tag: v0.2.1
-[SUCCESS] Generated version.h and version.c
-[SUCCESS] Updated VERSION file to 0.2.1
-```
-
-## Troubleshooting
-
-### Version Not Incrementing
- Ensure you're in a git repository
- Check that git tags exist with `git tag --list`
- Verify tag format matches `v*.*.*` pattern
-
-### Tag Already Exists
-If a tag already exists, the build will continue with the existing version:
-
-```
-[WARNING] Tag v0.2.1 already exists - using existing version
-```
-
-### Missing Git Information
-If git is not available, version files will show "unknown" for git hash and branch.
-
-## Benefits
-
-1. **Automatic Traceability**: Every build has a unique version
-2. **Build Metadata**: Includes timestamp, git commit, and branch information  
-3. **API Integration**: Version information accessible via C API
-4. **Zero Maintenance**: No manual version file editing required
-5. **Git Integration**: Automatic git tag creation for version history

-# NOSTR Core Integration Example
-
-This directory contains a complete example showing how to integrate the NOSTR Core library into your own projects.
-
-## What This Example Demonstrates
-
- **Library Initialization**: Proper setup and cleanup of the NOSTR library
- **Identity Management**: Key generation, bech32 encoding, and format detection
- **Event Creation**: Creating and signing different types of NOSTR events
- **Input Handling**: Processing various input formats (mnemonic, hex, bech32)
- **Utility Functions**: Using helper functions for hex conversion and error handling
- **CMake Integration**: How to integrate the library in your CMake-based project
-
-## Building and Running
-
-### Method 1: Using CMake
-
-```bash
-# Create build directory
-mkdir build && cd build
-
-# Configure with CMake
-cmake ..
-
-# Build
-make
-
-# Run the example
-./my_nostr_app
-```
-
-### Method 2: Manual Compilation
-
-```bash
-# Compile directly (assuming you're in the c_nostr root directory)
-gcc -I. examples/integration_example/main.c nostr_core.c nostr_crypto.c cjson/cJSON.c -lm -o integration_example
-
-# Run
-./integration_example
-```
-
-## Expected Output
-
-The example will demonstrate:
-
-1. **Identity Management Demo**
-   - Generate a new keypair
-   - Display keys in hex and bech32 format
-
-2. **Event Creation Demo**
-   - Create a text note event
-   - Create a profile event
-   - Display the JSON for both events
-
-3. **Input Handling Demo**
-   - Process different input formats
-   - Show format detection and decoding
-
-4. **Utility Functions Demo**
-   - Hex conversion round-trip
-   - Error message display
-
-## Integration Patterns
-
-### Pattern 1: CMake Find Package
-
-If NOSTR Core is installed system-wide:
-
-```cmake
-find_package(nostr_core REQUIRED)
-target_link_libraries(your_app nostr_core::static)
-```
-
-### Pattern 2: CMake Subdirectory
-
-If NOSTR Core is a subdirectory of your project:
-
-```cmake
-add_subdirectory(nostr_core)
-target_link_libraries(your_app nostr_core_static)
-```
-
-### Pattern 3: pkg-config
-
-If using pkg-config:
-
-```cmake
-find_package(PkgConfig REQUIRED)
-pkg_check_modules(NOSTR_CORE REQUIRED nostr_core)
-target_include_directories(your_app PRIVATE ${NOSTR_CORE_INCLUDE_DIRS})
-target_link_libraries(your_app ${NOSTR_CORE_LIBRARIES})
-```
-
-### Pattern 4: Direct Source Integration
-
-Copy the essential files to your project:
-
-```bash
-cp nostr_core.{c,h} nostr_crypto.{c,h} your_project/src/
-cp -r cjson/ your_project/src/
-```
-
-Then compile them with your project sources.
-
-## Code Structure
-
-### main.c Structure
-
-The example is organized into clear demonstration functions:
-
- `demo_identity_management()` - Key generation and encoding
- `demo_event_creation()` - Creating different event types
- `demo_input_handling()` - Processing various input formats
- `demo_utilities()` - Using utility functions
-
-Each function demonstrates specific aspects of the library while maintaining proper error handling and resource cleanup.
-
-### Key Integration Points
-
-1. **Initialization**
-   ```c
-   int ret = nostr_init();
-   if (ret != NOSTR_SUCCESS) {
-       // Handle error
-   }
-   ```
-
-2. **Resource Cleanup**
-   ```c
-   // Always clean up JSON objects
-   cJSON_Delete(event);
-   
-   // Clean up library on exit
-   nostr_cleanup();
-   ```
-
-3. **Error Handling**
-   ```c
-   if (ret != NOSTR_SUCCESS) {
-       printf("Error: %s\n", nostr_strerror(ret));
-       return ret;
-   }
-   ```
-
-## Customization
-
-You can modify this example for your specific needs:
-
- Change the `app_config_t` structure to match your application's configuration
- Add additional event types or custom event creation logic
- Integrate with your existing error handling and logging systems
- Add networking functionality using the WebSocket layer
-
-## Dependencies
-
-This example requires:
- C99 compiler (gcc, clang)
- CMake 3.12+ (for CMake build)
- NOSTR Core library and its dependencies
-
-## Testing
-
-You can test different input formats by passing them as command line arguments:
-
-```bash
-# Test with mnemonic
-./my_nostr_app "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about"
-
-# Test with hex private key
-./my_nostr_app "0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef"
-
-# Test with bech32 nsec
-./my_nostr_app "nsec1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
-```
-
-## Next Steps
-
-After studying this example, you can:
-
-1. Integrate the patterns into your own application
-2. Explore the WebSocket functionality for relay communication
-3. Add support for additional NOSTR event types
-4. Implement your own identity persistence layer
-5. Add networking and relay management features
-
