+# Breakpoint Utility
+
+The `breakpoint` utility allows you to create a Signal that evaluates to `true` if the current viewport matches the specified breakpoints.
+
+## Usage
+
+### Example
+
+```typescript
+import { Component } from '@angular/core';
+import { breakpoint, Breakpoint } from 'ui-layout';
+
+@Component({
+  selector: 'app-breakpoint-demo',
+  template: `
+    <div *uiBreakpoint="'tablet'">This content is visible only on tablet viewports.</div>
+  `,
+  imports: [BreakpointDirective],
+})
+export class BreakpointDemoComponent {
+  isTablet = breakpoint(Breakpoint.Tablet);
+}
+```
+
+### Breakpoints Table
+
+| Breakpoint   | CSS Media Query Selector                      |
+| ------------ | --------------------------------------------- |
+| `tablet`     | `(max-width: 1279px)`                         |
+| `desktop`    | `(min-width: 1280px) and (max-width: 1439px)` |
+| `desktop-l`  | `(min-width: 1440px) and (max-width: 1919px)` |
+| `desktop-xl` | `(min-width: 1920px)`                         |

+# ui-layout
+
+This library provides utilities and directives for responsive design in Angular applications.
+
+## Features
+
+- **Breakpoint Utility**: A function to detect viewport breakpoints using Angular's `BreakpointObserver`.
+- **Breakpoint Directive**: A structural directive to conditionally render templates based on viewport breakpoints.
+
+## Installation
+
+Ensure you have Angular and its dependencies installed. Then, include this library in your Angular project.
+
+## Usage
+
+### Breakpoint Utility
+
+The `breakpoint` function allows you to create a Signal that evaluates to `true` if the current viewport matches the specified breakpoints.
+
+```typescript
+import { breakpoint, Breakpoint } from 'ui-layout';
+
+const isTablet = breakpoint(Breakpoint.Tablet);
+```
+
+### Breakpoint Directive
+
+The `uiBreakpoint` directive conditionally includes a template based on the viewport's breakpoint.
+
+```html
+<ng-container *uiBreakpoint="'tablet'">
+  This content is visible only on tablet viewports.
+</ng-container>
+```
+
+## Breakpoints Table
+
+| Breakpoint   | CSS Media Query Selector                      |
+| ------------ | --------------------------------------------- |
+| `tablet`     | `(max-width: 1279px)`                         |
+| `desktop`    | `(min-width: 1280px) and (max-width: 1439px)` |
+| `dekstop-l`  | `(min-width: 1440px) and (max-width: 1919px)` |
+| `dekstop-xl` | `(min-width: 1920px)`                         |
+
+## Running Unit Tests
+
+Run `nx test ui-layout` to execute the unit tests.
