-### Import Map / deno.json Support
+### deno.json Support
 
-To use an import map or deno.json file with `"imports"` and/or `"scopes"`, add
-an `importMap` entry to your build object:
+Starting in dnt 0.42, the deno.json is auto-discovered. A config file can be
+explicitly specified by the `configFile` key:
 
 ```ts
 await build({
   // ...etc...
-  importMap: "deno.json",
+  configFile: import.meta.resolve("../deno.json"),
 });
 ```
 
-Note there is no support for the deno.json `importMap` key. Either embed that in
-your deno.json or specify the import map in this property directly. Also note
-that the deno.json is not auto-discovered—you must explicitly specify it.
