+## 1. 📖 Overview
+
+[🤗 MIGRATION-BENCH](https://huggingface.co/collections/AmazonScience/migrationbench-68125452fc21a4564b92b6c3)
+is a large-scale code migration benchmark dataset at the **repository** level,
+across multiple programming languages.
+
+- Current and initial release includes `java 8` repositories with the `maven` build system, as of May 2025.
+
+
+## 2. Datasets
+
+There are three datasets in [🤗 MIGRATION-BENCH](https://huggingface.co/collections/AmazonScience/migrationbench-68125452fc21a4564b92b6c3):
+- All repositories included in the datasets are available on GitHub, under the `MIT` or `Apache-2.0` license.
+
+| Index | Dataset                                       | Size  | Notes                                                                                               |
+|-------|-----------------------------------------------|-------|-----------------------------------------------------------------------------------------------------|
+| 1     | [🤗 `AmazonScience/migration-bench-java-full`](https://huggingface.co/datasets/AmazonScience/migration-bench-java-full)         | 5,102 | Each repo has a test directory or at least one test case                              |
+| 2     | [🤗 `AmazonScience/migration-bench-java-selected`](https://huggingface.co/datasets/AmazonScience/migration-bench-java-selected) |   300 | A **subset** of [🤗 `migration-bench-java-full`](https://huggingface.co/datasets/AmazonScience/migration-bench-java-full)                                          |
+| 3     | [🤗 `AmazonScience/migration-bench-java-utg`](https://huggingface.co/datasets/AmazonScience/migration-bench-java-selected)      | 4,814 | The unit test generation (utg) dataset, **disjoint** with [🤗 `migration-bench-java-full`](https://huggingface.co/datasets/AmazonScience/migration-bench-java-full)|
+
+
+## 3. Metadata
+
+Metadata is provided in the `csv` file for each dataset:
+
+1. `repo (str)`: The original repo URL without the `https://github.com/` prefix
+1. `base_commit (str)`: Base commit id
+    - At this commit with `java 8` and `maven`, the repository is able to (1) compile and (2) pass existing unit tests and integration tests if any
+    - It is the starting point for code migration from `java 8`
+1. `num_java_files (int)`: Number of `*.java` files in the repository at `base_commit`, similarly for all other `num_*` columns
+1. `num_loc (int)`: Lines of code for the repository
+1. `num_pom_xml (int)`: Number of modules (`pom.xml` files) in the repository
+1. `num_src_test_java_files (int)`: Number of `*.java` files in the dedicated `src/test/` directory
+1. `num_test_cases (int)`: Number of test cases, based on running the `mvn -f test .` command in the root directory
+    - Non negative values indicate number of test cases is parsed correctly from the output
+    - Negative values means it's unable to parse the output: `[INFO] Results:` (`-2`) or `[INFO] Tests run:` (`-1`) regex is missing
+1. `license (str)`: The license of the repository, either `MIT` or `Apache2.0` for the whole dataset
+
+### 3.1 Parsing Java Test Cases
+
+Here is a sample `maven -f test .` command output to get valid `num_test_cases`:
+
+```
+...
+[INFO] Results:
+[INFO]
+[INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0
+...
+```
