 ## XAH
 XAH is the public, counterparty-free asset native to Xahau and functions primarily as network gas. Transactions submitted to the Xahau network must supply an appropriate amount of XAH, to be burnt by the network as a fee, in order to be successfully included in a validated ledger. In addition, XAH also acts as a bridge currency within the Xahau DEX. XAH is traded on the open-market and is available for anyone to access. Xahau was created in 2023 with a supply of 600 million units of XAH.

  * Steps required to add new features to the code:
  *
- * 1) In this file, increment `numFeatures` and add a uint256 declaration
- *    for the feature at the bottom
- * 2) Add a uint256 definition for the feature to the corresponding source
- *    file (Feature.cpp). Use `registerFeature` to create the feature with
- *    the feature's name, `Supported::no`, and `VoteBehavior::DefaultNo`. This
- *    should be the only place the feature's name appears in code as a string.
- * 3) Use the uint256 as the parameter to `view.rules.enabled()` to
- *    control flow into new code that this feature limits.
- * 4) If the feature development is COMPLETE, and the feature is ready to be
- *    SUPPORTED, change the `registerFeature` parameter to Supported::yes.
- * 5) When the feature is ready to be ENABLED, change the `registerFeature`
- *    parameter to `VoteBehavior::DefaultYes`.
- * In general, any newly supported amendments (`Supported::yes`) should have
- * a `VoteBehavior::DefaultNo` for at least one full release cycle. High
- * priority bug fixes can be an exception to this rule of thumb.
+ * 1) Add the appropriate XRPL_FEATURE or XRPL_FIX macro definition for the
+ *    feature to features.macro with the feature's name, `Supported::no`, and
+ *    `VoteBehavior::DefaultNo`.
+ *
+ * 2) Use the generated variable name as the parameter to `view.rules.enabled()`
+ *    to control flow into new code that this feature limits. (featureName or
+ *    fixName)
+ *
+ * 3) If the feature development is COMPLETE, and the feature is ready to be
+ *    SUPPORTED, change the macro parameter in features.macro to Supported::yes.
+ *
+ * 4) In general, any newly supported amendments (`Supported::yes`) should have
+ *    a `VoteBehavior::DefaultNo` indefinitely so that external governance can
+ *    make the decision on when to activate it. High priority bug fixes can be
+ *    an exception to this rule. In such cases, ensure the fix has been
+ *    clearly communicated to the community using appropriate channels,
+ *    then change the macro parameter in features.macro to
+ *    `VoteBehavior::DefaultYes`. The communication process is beyond
+ *    the scope of these instructions.
+ *
  *
  * When a feature has been enabled for several years, the conditional code
  * may be removed, and the feature "retired". To retire a feature:
- * 1) Remove the uint256 declaration from this file.
- * 2) MOVE the uint256 definition in Feature.cpp to the "retired features"
- *    section at the end of the file.
- * 3) CHANGE the name of the variable to start with "retired".
- * 4) CHANGE the parameters of the `registerFeature` call to `Supported::yes`
- *    and `VoteBehavior::DefaultNo`.
+ *
+ * 1) MOVE the macro definition in features.macro to the "retired features"
+ *    section at the end of the file, and change the macro to XRPL_RETIRE.
+ *
  * The feature must remain registered and supported indefinitely because it
