 The components are:
 1. **Model**: A descriptive name for the model type or architecture.
-2. **Version (Optional)**: Denotes the model version number, starting at `v1` if not specified, formatted as `v<Major>.<Minor>`.
-    - Best practice to include model version number only if model has multiple versions and assume the unversioned model to be the first version and/or check the model card.
+2. **Version**: (Optional) Denotes the model version number, formatted as `v<Major>.<Minor>`
+    - If model is missing a version number then assume `v0.0` (Prerelease)
 3. **ExpertsCount**: Indicates the number of experts found in a Mixture of Experts based model.
 4. **Parameters**: Indicates the number of parameters and their scale, represented as `<count><scale-prefix>`:
     - `T`: Trillion parameters.

+#### Parsing Above Naming Convention
+
+To correctly parse a well formed naming convention based gguf filename, it is recommended to read from right to left using `-` as the delimiter. This strategy allow for the most flexibility in model name to include dashes if they so choose, while at the same time allowing for version string to be optional. This approach also gives some future proofing to extend the format if needed in the future.

+For example:
+
+  * `mixtral-v0.1-8x7B-Q2_K.gguf`:
+    - Model Name: Mixtral
+    - Version Number: v0.1
+    - Expert Count: 8
+    - Parameter Count: 7B
+    - Quantization: Q2_K
+
+  * `Hermes-2-Pro-Llama-3-8B-F16.gguf`:
+    - Model Name: Hermes 2 Pro Llama
+    - Version Number: v0.0 (`<Version>-` missing)
+    - Expert Count: 0 (`<ExpertsCount>x` missing)
+    - Parameter Count: 8B
+    - Quantization: F16
