### Fixing spurious errors in the IDE
When you open the project in the IDE, you might see red lines under valid code,
to fix this problem:
1. Delete the file `Interfaces.scala` in `src/main/scala/scalashop`
2. Open the file `package.scala` in `src/main/scala/scalashop`
3. In `package.scala`, copy-paste the content of https://gitlab.epfl.ch/lamp/cs206-2020/snippets/33/raw
**below** the line `import org.scalameter._`
4. Save the file, quit the IDE and run `launchIDE` again.
