 ### Metals
 
 When using Metals, the `-bootstrapped` projects are not exported by default.
 Normally this is fine, but if you're working on certain modules like `scaladoc`
 you'll actually want these modules exported. In order to achieve this you'll
-first want to ensure you're using `sbt` as your build server instead of the
-default Bloop. You can achieve this with the `Metals: Switch Build Server`
-command and then choosing sbt. Once you do this, you'll want to find and change
-the following under `commonBootstrappedSettings` which is found in the
-[`Build.scala`](https://github.com/lampepfl/dotty/blob/main/project/Build.scala)
-file.

 ### IntelliJ
 
 In IntelliJ IDEA, we recommend importing the dotty codebase through BSP, then
