-This is the repository for Delta Lake Connectors. It includes
-- [Delta Standalone](https://docs.delta.io/latest/delta-standalone.html): a native library for reading and writing Delta Lake metadata.
-- Connectors to popular big-data engines (e.g., [Apache Hive](https://hive.apache.org/), [Presto](https://prestodb.io/), [Apache Flink](https://flink.apache.org/)) and to common reporting tools like [Microsoft Power BI](https://powerbi.microsoft.com/).

+## Delta Standalone
 
 Delta Standalone, formerly known as the Delta Standalone Reader (DSR), is a JVM library to read **and write** Delta tables. Unlike https://github.com/delta-io/delta, this project doesn't use Spark to read or write tables and it has only a few transitive dependencies. It can be used by any application that cannot use a Spark cluster.
 - To compile the project, run `build/sbt standalone/compile`

 ## Power BI connector
 The connector for [Microsoft Power BI](https://powerbi.microsoft.com/) is basically just a custom Power Query function that allows you to read a Delta table from any file-based [data source supported by Microsoft Power BI](https://docs.microsoft.com/en-us/power-bi/connect-data/desktop-data-sources). Details can be found in the dedicated [README.md](/powerbi/README.md).

-- Before local debugging of `standalone` tests in IntelliJ, run all `standalone` tests using SBT. This helps IntelliJ recognize the golden tables as class resources.
