The ions docs here: https://docs.datomic.com/cloud/ions/ions-reference.html frequently use the ion namespace alias in code examples, e.g. (ion/get-env) but I cannot seem to find the full namespace symbol to require that anywhere on that page or in the docs or the ion-starter repo. Am I missing where it says this? (I can probably figure it out but might be useful to have the full require code somewhere). (edit: I guess it's just datomic.ions but I don't see that mentioned anywhere)
