 ### Usage
 
-Create a new Application using Angular CLI and import the SearchLibModule and add it to the imports array of the module. Also create a new service that implements the ISearchService interface exported by the search library. This service will be used by the exported component to make API calls whenever needed.

+### Required Global Styles
+
+The search component uses Angular CDK overlays for the dropdown, which require global styles to function properly.
+
+### Styling and Theming
+
+The search component uses CSS custom properties (CSS variables) for theming, allowing you to customize colors without modifying the library code. You can override these variables in your application's global styles or in a component-specific stylesheet.
+
+#### Available CSS Variables
+
+````scss
+sourceloop-search {
+  --search-background: #f7f7f7; /* Background of the search container */
+  --search-input-background: #f1f3f4; /* Background of the input field */
+  --search-input-text-color: #6b6b6b; /* Text color in the input field */
+  --search-border-hover: #a53159; /* Border color on hover */
+  --search-border-focus: #90003b; /* Border color when focused */
+  --search-dropdown-background: #90003b; /* Background of the category dropdown (on hover/focus) */
+  --search-dropdown-text-color: #ffffff; /* Text color in the category dropdown (on hover/focus) */
+  --search-highlight-bg: #fee8e8; /* Background color for highlighted suggestions */
+  --search-heading-color: #9c9c9c; /* Color of category headings */
+  --search-text-color: #333; /* General text color */
+  --search-icon-color: #33333380; /* Color of icons */
+}
+
+####Example: Custom Theming To customize the search component, add the following
+    to your `component.scss` ```scss 
+
+// Customize component colors
+
+:host ::ng-deep sourceloop-search {
+  --search-border-hover: #5c26f1 !important;
+  --search-border-focus: #5c26f1 !important;
+  --search-dropdown-background: #5c26f2 !important;
+}
+````
+
+This allows you to match the search component's appearance with your application's design system.
