 This project provides [a C library rwkv.h](rwkv.h) and [a convinient Python wrapper](rwkv%2Frwkv_cpp_model.py) for it.
 
-**TODO**:
+**TODO (contributions welcome!)**:
 
-1. Measure performance and perplexity of different model sizes and data types
-2. Write a good `README.md` (motivation, benchmarks, perplexity) and publish links to this repo
-3. Create pull request to main `ggml` repo with all improvements made here
+1. Measure latency and perplexity of different model sizes (169M to 14B) and data types (FP32, FP16, Q4_0, Q4_1)
+2. Test on Linux (including Colab) and MacOS
+3. Make required memory calculation more robust (see #4)

 ```commandline
 git clone https://github.com/saharNooby/rwkv.cpp.git
 cd rwkv.cpp

+
+### 2. Get the rwkv.cpp library
+
+#### Option 2.1. Download a pre-compiled library
+
+##### Windows
+
+Check out [Releases](https://github.com/saharNooby/rwkv.cpp/releases), download appropriate ZIP for your CPU, extract `rwkv.dll` file into `bin\Release\` directory inside the repository directory.
+
+To check whether your CPU supports AVX2 or AVX-512, [use CPU-Z](https://www.cpuid.com/softwares/cpu-z.html).
+
+#### Option 2.2. Build the library yourself
+
+##### Windows
+
+**Requirements**: [CMake](https://cmake.org/download/), MSVC compiler.
+
+```commandline
 cmake -DBUILD_SHARED_LIBS=ON .
 cmake --build . --config Release
 ```
 
 If everything went OK, `bin\Release\rwkv.dll` file should appear.
