 ### Using IntelliJ
 
 You can use the built-in sbt shell in IntelliJ without any problems. However, the built-in "Build Project" command may not work. To fix the issue, go to Project Structure -> Project Settings -> Modules and follow these steps:
 
-- Mark `src/main/scala` and `src/main/scala-spark2` as "Sources" and `src/test/scala` and `src/test/scala-spark2` as "Tests" for the `spark2_4` module
-- Mark `src/main/scala` and `src/main/scala-spark3` as "Sources" and `src/test/scala` and `src/test/scala-spark3` as "Tests" for the `spark3_0` module
-- Remove the `root` and `hyperspace-sources` modules
+- Mark `src/main/scala` and `src/main/scala-spark2` as "Sources" and `src/test/scala` and `src/test/scala-spark2` as "Tests" for the `spark2_4` module.
+- Mark `src/main/scala` and `src/main/scala-spark3` as "Sources" and `src/test/scala` and `src/test/scala-spark3` as "Tests" for the `spark3_0` module.

 Additionally, you might have to run `sbt buildInfo` if you encounter an error like `object BuildInfo is not a member of package com.microsoft.hyperspace` for the first build.
