 # tokenizers-cpp
 
-Cross platform universal tokenizer binding to HF and sentencepiece
+This project provides a cross-platform C++ tokenizer binding library that can be universally deployed.
+It wraps and binds the [HuggingFace tokenizers library](https://github.com/huggingface/tokenizers)
+and [sentencepiece](https://github.com/google/sentencepiece) and provides a minimum common interface in C++.
+
+The main goal of the project is to enable tokenizer deployment for language model applications
+to native platforms with minimum dependencies and remove some of the barriers of
+cross-language bindings. This project is developed in part with and
+used in [MLC LLM](https://github.com/mlc-ai/mlc-llm). We have tested the following platforms:
+
+- iOS
+- Android
+- Windows
+- Linux
+- Web browser
+
+## Getting Started
+
+The easiest way is to add this project as a submodule and then
+include it via `add_sub_directory` in your CMake project.
+You also need to turn on `c++17` support.
+
+- First, you need to make sure you have rust installed.
+- If you are cross-compiling make sure you install the necessary target in rust.
+  For example, run `rustup target add aarch64-apple-ios` to install iOS target.
+- You can then link the libary
+
+See [example](example) folder for an example CMake project.
+
+### Example Code
+
+```c++
+// - dist/tokenizer.json
+void HuggingFaceTokenizerExample() {
+  // Read blob from file.
+  auto blob = LoadBytesFromFile("dist/tokenizer.json");
+  // Note: all the current factory APIs takes in-memory blob as input.
+  // This gives some flexibility on how these blobs can be read.
+  auto tok = Tokenizer::FromBlobJSON(blob);
+  std::string prompt = "What is the capital of Canada?";
+  // call Encode to turn prompt into token ids
+  std::vector<int> ids = tok->Encode(prompt);
+  // call Decode to turn ids into string
+  std::string decoded_prompt = tok->Decode(ids);
+}
+
+void SentencePieceTokenizerExample() {
+  // Read blob from file.
+  auto blob = LoadBytesFromFile("dist/tokenizer.model");
+  // Note: all the current factory APIs takes in-memory blob as input.
+  // This gives some flexibility on how these blobs can be read.
+  auto tok = Tokenizer::FromBlobSentencePiece(blob);
+  std::string prompt = "What is the capital of Canada?";
+  // call Encode to turn prompt into token ids
+  std::vector<int> ids = tok->Encode(prompt);
+  // call Decode to turn ids into string
+  std::string decoded_prompt = tok->Decode(ids);
+}
+```
+
+### Extra Details
+
+Currently, the project generates three static libraries
+- `libtokenizers_c.a`: the c binding to tokenizers rust library
+- `libsentencepice.a`: sentencepiece static library
+- `libtokenizers_cpp.a`: the cpp binding implementation
+
+If you are using an IDE, you can likely first use cmake to generate
+these libraries and add them to your development environment.
+If you are using cmake, `target_link_libraries(yourlib tokenizers_cpp)`
+will automatically links in the other two libraries.
+You can also checkout [MLC LLM](https://github.com/mlc-ai/mlc-llm)
+for as an example of complete LLM chat application integrations.
+
+## Javascript Support
+
+We use emscripten to expose tokenizer-cpp to wasm and javascript.
+Checkout [web](web) for more details.
+
+## Acknowledgements
+
+This project is only possible thanks to the shoulders open-source ecosystems that we stand on.
+This project is based on sentencepiece and tokenizers library.
