I originally added the 2nd example as the firstw as for the old way that Circle CI did things (v1). It seems the other example has now been updated: [https://github.com/nim-lang/Nim/wiki/BuildServices/_compare/cc4ad91c2478b5fef2e0d88ad7cc48ba8e298f55...d18466d165a66983617344489308e4304ae31c42](https://github.com/nim-lang/Nim/wiki/BuildServices/_compare/cc4ad91c2478b5fef2e0d88ad7cc48ba8e298f55...d18466d165a66983617344489308e4304ae31c42) The 2 examples that exist at the moment are very similar, though the second builds on Alpine Linux and on Ubuntu.
