Dandandan opened a new issue #71: URL: https://github.com/apache/arrow-datafusion/issues/71
**Describe the bug** The `README.md` files in the root and in the `datafusion` directory are (mostly) copies of each other. There are small differences between the two, e.g. added functionality that is not included. **Expected outcome ** Most of the documentation of datafusion could be in the root. Details about technical design and contributing could move to the `datafusion/README.md` file. -- This is an automated message from the Apache Git Service.
