 You can enable an experimental feature by:
 
-1. Using the `--x-{feature}` flag. This is intended for one-off invocations of
-   Task to test out experimental features. You can also disable a feature by
-   specifying a falsy value such as `--x-{feature}=false`.
-1. Using the `TASK_X_{FEATURE}=1` environment variable. This is intended for
-   permanently enabling experimental features in your environment.
+1. Using the relevant environment variable in front of a task command. For
+   example, `TASK_X_{FEATURE}=1 task {my-task}`. This is intended for one-off
+   invocations of Task to test out experimental features.
+1. Using the relevant environment variable in your "dotfiles" (e.g. `.bashrc`,
+   `.zshrc` etc.). This is intended for permanently enabling experimental
+   features in your environment.
+1. Creating a `.env` file in the same directory as your root Taskfile that
+   contains the relevant environment variables. e.g.
 
-Flags will always override environment variables.
+```shell
+# .env
