+This is the benchmark of [LLM4Decompile](https://github.com/albertan017/LLM4Decompile) project.
+
+## About
+* **Decompile-Bench** is the first open-source dataset comprising two million binary-source function pairs condensed from 100 million collected function pairs, i.e., 450GB of binaries compiled from permissively licensed GitHub projects.
+* **C and C++ Support:** These datasets include both **C** and **C++** source code, whereas earlier models (LLM4Decompile-V1.5, V2) and the HumanEval-Decompile dataset were limited to C only.
+
+## Columns
+It contains the following columns:
+```
+{
+"name":"demangled name for the function",
+"code":"source code",
+"asm":"assembly",
+"file":"source code path"
+}
+```
+
+## Meta data
+* [raw data](https://huggingface.co/datasets/LLM4Binary/decompile-bench-raw) contains 100M raw fuctions that decompile-bench is condensed from.
+* The [binaries](https://huggingface.co/datasets/LLM4Binary/decompile-bench-bins) for the decompile-bench is also released, with debugging information helpful for tracing types and names.
