+## Compiler version
+
+If you're not sure what version you're using, run `print scalaVersion` from sbt
+(if you're running scalac manually, use `scalac -version` instead).
+
+## Minimized example
+
+<!--
+This code should be self-contained, reproducible (i.e. produces the expected error/warning message) and as small as possible.
+
+Ideally, we should be able to just copy this code in a file and run `scalac` (and maybe `scala`) to reproduce the issue.
+
+For a good example, see https://github.com/lampepfl/dotty/issues/18657
+-->
+
+```Scala
+printl("hello, world")
+```
+
+## Output Error/Warning message
+
+<!--
+Here, please provide the produced error/warning message that is confusing/unhelpful, etc.
+
+for example:
+-->
+
+```scala
+-- [E006] Not Found Error: ----------------
+1 |printl("hello, world")
+  |^^^^^^
+  |Not found: printl
+1 error found
