 - Each LWC should reside in its own folder under `force-app/main/default/lwc/`.
-- The folder name should match the component name (e.g., `myComponent` for `myComponent`).
+- The folder name should match the component name (e.g., `myComponent` folder for the `myComponent` component).

 ### 8. Performance Optimization
 
 #### Conditional Rendering
+Prefer `lwc:if`, `lwc:elseif` and `lwc:else` for conditional rendering (API v58.0+). Legacy `if:true` / `if:false` are still supported but should be avoided in new components.
+
 ```html
 <!-- Use template directives for conditional rendering -->
-<template if:true={isLoading}>
+<template lwc:if={isLoading}>
     <lightning-spinner alternative-text="Loading..."></lightning-spinner>
 </template>
-
