 ## Functionality
@@ -20,13 +21,13 @@ Skyforge takes a user provided regex pattern, performs a walk on a `./spec` dir,
 For each "device" matched, skyforge then maps to all consituent files:
 
 - Layer - from the `common.yaml` file in parent dir and maps the region
-- Zonal - from the first group of chars in filename up to a `-` which is expected to be region and zone
+- Zonal - from the first group of chars in filename up to a `-`
-- Regional - from the `<region>/common/<network>.yaml` of containing folder where network matches the layer info
+- Regional - from value of `common.fabric` field in `Layer` file
-- Partitional - from either layer (common.yaml) or regional yaml
+- Partitional - from value of `regional.partition` field in `Regional` file
 
 Once all files are found, a compiled specifcation is built.
  This spec is then passed to Tera as context.
- Tera then loads the template files for that layer and renders the configuration files.
