# Getting Started

## Build Requirements

* **CMake** >= 4.0
* A C99-compatible compiler

## Installation

### CMake (Recommended)

Use CMake's `FetchContent` to automatically download the pre-built library from [GitHub Releases](https://github.com/tashigg/tashi-vertex-c/releases):

```cmake
include(FetchContent)

set(TASHI_VERTEX_VERSION "0.12.0")
set(TASHI_VERTEX_URL "https://github.com/tashigg/tashi-vertex-c/releases/download/v${TASHI_VERTEX_VERSION}/tashi-vertex-${TASHI_VERTEX_VERSION}.zip")

FetchContent_Declare(
    TASHI_VERTEX
    URL ${TASHI_VERTEX_URL}
    DOWNLOAD_EXTRACT_TIMESTAMP TRUE
)

FetchContent_MakeAvailable(TASHI_VERTEX)

# Create an imported library target
add_library(TASHI_VERTEX SHARED IMPORTED GLOBAL)

set(TASHI_VERTEX_LIB_DIR "${tashi_vertex_SOURCE_DIR}/lib")

if(WIN32)
    set_target_properties(TASHI_VERTEX PROPERTIES IMPORTED_LOCATION "${TASHI_VERTEX_LIB_DIR}/tashi-vertex.dll")
elseif(APPLE)
    set_target_properties(TASHI_VERTEX PROPERTIES IMPORTED_LOCATION "${TASHI_VERTEX_LIB_DIR}/libtashi-vertex.dylib")
else()
    set_target_properties(TASHI_VERTEX PROPERTIES IMPORTED_LOCATION "${TASHI_VERTEX_LIB_DIR}/libtashi-vertex.so")
endif()
```

Then link against it in your target:

```cmake
target_include_directories(my_app PRIVATE "${tashi_vertex_SOURCE_DIR}/include")
target_link_libraries(my_app PRIVATE TASHI_VERTEX)
```

### Manual

Download the latest `.zip` release from [GitHub Releases](https://github.com/tashigg/tashi-vertex-c/releases) and extract it. The archive contains `include/` and `lib/` directories that you can integrate into your build system of choice.

## Quick Start

Generate a keypair for your node:

```c
#include <stdio.h>
#include <tashi-vertex/tashi-vertex.h>

int main() {
  TVKeySecret secret;
  tv_key_secret_generate(&secret);

  TVKeyPublic public;
  tv_key_secret_to_public(&secret, &public);

  // encode to Base58 for display
  uint8_t der[TV_KEY_SECRET_DER_LENGTH];
  tv_key_secret_to_der(&secret, der, TV_KEY_SECRET_DER_LENGTH);

  char b58[tv_base58_encode_length(TV_KEY_SECRET_DER_LENGTH) + 1];
  size_t b58_len = sizeof(b58);
  tv_base58_encode(der, TV_KEY_SECRET_DER_LENGTH, b58, &b58_len);
  b58[b58_len] = '\0';

  printf("Secret: %s\n", b58);

  return 0;
}
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.tashi.network/developers/developers/vertex-c/getting-started.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
