 ### Explicit, manual configuration
 Maybe using the generated `hie.yaml` file does not suit you.
 E.g., it still does not work, or you want to fine-tune the configuration.
-We recommend to start from the `hie.yaml` file generated by `implicit-hie` (see previous section) and modify it to suit your needs.
 
-For that you need to know what *components* your project has, and the path associated with each one.
-So you will need some knowledge about
-[stack](https://docs.haskellstack.org/en/stable/build_command/#components) or [cabal](https://cabal.readthedocs.io/en/latest/cabal-commands.html?#cabal-v2-build) components.

-**For a full explanation of how to configure it manually, refer to the [hie-bios documentation](https://github.com/mpickering/hie-bios/blob/master/README.md).**
+In that case, refer to the [hie-bios explicit configuration documentation](https://github.com/haskell/hie-bios#explicit-configuration).
+Keep in mind that you can start from the `hie.yaml` file generated by `implicit-hie` (see previous section) and modify it to your liking.
 
 #### Examples of explicit `hie-yaml` configurations
 
+##### Basic Stack
+```yaml
+cradle:
+  stack:
+```
+
+##### Basic Cabal
+```yaml
+cradle:
+  cabal:
+```
+
 ##### Single Stack component
 
 ```yaml
