 This document provides guidelines on versioning in SDMX, including the following:
 
-* Documenting "how-to" version SDMX artefacts following "semantic versioning;"
-* Documenting best practices for wildcarding dependencies;
-* Documenting best practices around extensions; and
-* Documenting best practices for implementing semantic versioning in an existing SDMX environment.
+- Documenting "how-to" version SDMX artefacts following "semantic versioning;"
+- Documenting best practices for wildcarding dependencies;
+- Documenting best practices around extensions; and
+- Documenting best practices for implementing semantic versioning in an existing SDMX environment.
 
 This document is broken down into the following sections:
 
-* [Versioning in SDMX](Versioning%20in%20SDMX.md), which outlines how artefacts can be versioned in SDMX, what semantic versioning is, and how semantic versioning complements the SDMX standard. This document also provides recommendations on [Implementing semantic versioning in an existing SDMX enviroment](Versioning%20in%20SDMX.md#implementing-semantic-versioning-in-an-existing-sdmx-enviroment).
-* [General Recommendations for Maintainable Artefacts](./General%20Recommendations%20for%20Maintainable%20Artefacts.md),  which details actions applicable to any maintainable artefact and how those actions impact versioning.
-* [Artefact Specific Recommendations](./Artefact%20Specific%20Recommendations/),  which detail how each action made to a maintainable artefact can impact it's version and what wildcarding
-considerations should be considered within that artefact.

 ## Conventions Used in These Guidelines
 
 ### Minimum Version Changes
 
 In this document, when we recommend a minimum version change, it means the following:
 
-| Minimum Version Change | Action |
-|:----------------------:|--------|
-| Major                  | Increment the first digit in the version number |
-| Minor                  | Increment the first or second digit in the version number |
-| Patch                  | Increment the first or second or third digit in the version number |
+| Minimum Version Change | Action                                                             |
+| :--------------------: | ------------------------------------------------------------------ |
+|         Major          | Increment the first digit in the version number                    |
+|         Minor          | Increment the first or second digit in the version number          |
+|         Patch          | Increment the first or second or third digit in the version number |
 
 ### Wildcarding References
 
 When referring to wildcarding, the following conventions are used:
 
-| Level | Format | Meaning |
-|:-----:|--------|---------|
-| Patch | X.Y.Z+ | This matches the *latest available stable semantic* version of an artefact in form of **`x.y.z`** where `x.y.z` >= `X.Y.Z`. |
-| Minor | X.Y+.Z | This matches the *latest available stable semantic* version of an artefact in form of **`X.y.z`** where `y.z` >= `Y.Z`. |
-| Major | X+.Y.Z | This matches the *latest available stable semantic* version of an artefact in form of **`X.Y.z`** where `z` >= `Z`. |
+| Level | Meaning | Format                                                                                                                      |
+| :---: | ------- | --------------------------------------------------------------------------------------------------------------------------- |
+| Patch | X.Y.Z+  | This matches the _latest available stable semantic_ version of an artefact in form of **`x.y.z`** where `x.y.z` >= `X.Y.Z`. |
+| Minor | X.Y+.Z  | This matches the _latest available stable semantic_ version of an artefact in form of **`X.y.z`** where `y.z` >= `Y.Z`.     |
+| Major | X+.Y.Z  | This matches the _latest available stable semantic_ version of an artefact in form of **`X.Y.z`** where `z` >= `Z`.         |
 
 ### Wildcard Reference Icons
 
 The following icons are used to indicate recommendations for wildcard references:
 
-| Icon | Meaning |
-|:----:|---------------|
-| 🟢 | There are no concerns with having a wildcard reference at this level. |
-| ⚠️ | Take care in having a wildcard reference at this level; specific concerns will be noted. |
-| 🟥 | Do not have a wildcard reference at this level. |
