 All local datablocks across all assets of a production must have a unique name. To faciliate this, each asset is assigned a mnemonic that must remain unique within a given production. For example, a character named "Elder Sprite" might get the mnemonic "ES". The max length of this mnemonic is not limited, but the shorter the better. If a minor prop in the production is called "Electric Switch", it can not have the mnemonic "ES", because it's already taken. So, "ELSW" would be fine. 
 
+This mnemonic will be used in the names of datablocks, to make sure all names are unique, not just in a single file, but the whole production. This is useful/necessary because of the way Blender's Override system works, which relies on making local copies of linked object hierarchies, meaning all assets need to be able to exist in the same namespace without collisions.

 ## Asset Collections
 
 We use prefixes for the root collections of assets to help distinguish different types of assets in the Outliner of a complex shot file. The name of the asset itself should be lowercase.

 Note that there's no technical distinction between different types of assets. This is purely for organizational purposes and comfort.
 
-The immediate sub-collections of the root collection are strictly defined by our Asset Pipeline add-on, as being `{mnemonic}-{task_layer}`. Task Layers are the different data layers that make up an asset, such as Modeling, Rigging, and Shading. Beyond those two layers, any number of collections may be created according to the needs and wants of the person responsible for a given Task Layer. However, each sub-collection should still start with `{mnemonic}-{task_layer}-`.

 ## Asset Datablocks
-- All local datablocks (Mesh, Material, Action, etc.) of an asset must start with or at least include the asset's mnemonic, eg `ES-eye.L`. This is automated by the Asset Pipeline add-on.
+- All local datablocks of an asset (Object, Mesh, Material, Action, etc.) must include either the asset's mnemonic or full name (both is not necessary). Eg., `RIG-elder_sprite` or `GEO-ES-eye.L`. This is automated by the Asset Pipeline add-on.
 - Object Data and Shape Keys should be named the same as the containing Object. This is automated by the Asset Pipeline add-on.
-- Object names must not end with a `.00x` suffix. This is enforced by the Asset Pipeline add-on.

-    - In some cases it may be truly unreasonable to expect an artist to give every object in an asset a unique, manually typed in name, like when building a house out of a hundred wooden slab objects. In these cases, the Batch Rename Datablocks built-in add-on should be used to give groups of objects the same name, then in a subsequent step replace the `.` in the `.00x` suffixes with an `_` instead.
+    - When there's too many objects to manually name, like when building a house out of a hundred wooden plank objects, the **Batch Rename Datablocks** built-in add-on should be used to give groups of objects the same name. Then replace the `.` in the `.00x` suffixes with an `_` instead, so `GEO-HS-wooden_plank.023` becomes `GEO-HS-wooden_plank_023`.
-    - The purpose of this is so that, when there are >1 copies of this asset overridden in a file, every object in the same copy of the asset will have the same number suffix. This would not be the case if we didn't replace the `.` with an `_` before publishing the asset.
+    - The purpose of this is that when there are >1 copies of this asset overridden (and therefore local) in a file, every object in the same copy of the asset will have the same number suffix. The first copy will have no suffix. The second copy of the asset will have object names like `GEO-HS-wooden_plank_023.001`, which is fine. If we didn't do this step, this object would instead end up getting named `GEO-HS-wooden_plank.024`, which is not fine because now the suffix number has no correlation with which overridden copy of the asset this object belongs to.
-    - Without this step, debugging shot files with multiple copies of an asset becomes an absolute nightmare, and if you add the occasional deletion of copies into the mix, it could even confuse Blender's Library Override system and break shots.
