 ## Leveraging precomputed results
 
-Whether to allow for manual intervention for tough cases, or simply to reduce processing time, *NiBabies* can allow the use of certain pre-computed files during processing.
-Initial support is limited to the following files:
-- Anatomical mask in T1w space
-- Antomical segmentation (aseg) in T1w space
+Whether manual intervention is required, or you want to reduce processing time, *NiBabies* allow the use of certain pre-computed files during processing, which can skip part of the workflow.
+Support is limited to the following files:
+- Anatomical mask in T1w or T2w space
+- Antomical segmentation (aseg) in T1w or T2w space
 
 To use pre-computed results, one or more [BIDS Derivatives](https://bids-specification.readthedocs.io/en/stable/05-derivatives/01-introduction.html#bids-derivatives) directories must be passed in to *NiBabies* using the `--derivatives` flag.
 Derivative directories must include a [`dataset_description.json` and the required fields](https://bids-specification.readthedocs.io/en/stable/03-modality-agnostic-files.html#derived-dataset-and-pipeline-description).
-Additionally, files must include the `space-orig` key-value pair in the name.
+Additionally, files must include the `space-T1w` or `space-T2w` key-value pair in the filenames, and a matching sidecar JSON file with the `SpatialReference` field defined.
 
 A sample layout of a derivatives directory can be found below:

 ## Multi-atlas segmentation with joint label fusion
 
 By default, *NiBabies* will run [FSL FAST](https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FAST) for tissue segmentation, and Infant FreeSurfer for segmentation labels.

 1. If the `YY.MINOR` match the version you used, but the `MICRO` has changed, it is a bug-fix release.
 Check the [release notes](https://github.com/nipreps/nibabies/releases) - if the fixes do not pertain to your data, there is no need to upgrade.
