In addition to posting a “minimal working example”, remember to post the _actual_ code instead of an _image_ of the code, since one cannot cut and paste from an image. Rember to put the code inside backticks (see here: [PSA: how to quote code with backticks](https://discourse.julialang.org/t/psa-how-to-quote-code-with-backticks/7530))
