+# Permission System Documentation
+
+This document outlines the permission system implemented in the Inventory Manager application.
+
+## Permission Structure
+
+Permissions follow this naming convention:
+
+- Page access: `access:{page_name}`
+- Actions: `{action}:{resource}`
+
+Examples:
+- `access:products` - Can access the Products page
+- `create:products` - Can create new products
+- `edit:users` - Can edit user accounts
+
+## Permission Components
+
+### PermissionGuard
+
+The core component that conditionally renders content based on permissions.
+
+```tsx
+<PermissionGuard 
+  permission="create:products"
+  fallback={<p>No permission</p>}
+>
+  <button>Create Product</button>
+</PermissionGuard>
+```
+
+Options:
+- `permission`: Single permission code
+- `anyPermissions`: Array of permissions (ANY match grants access)
+- `allPermissions`: Array of permissions (ALL required)
+- `adminOnly`: For admin-only sections
+- `page`: Page name (checks `access:{page}` permission)
+- `fallback`: Content to show if permission check fails
+
+### PermissionProtectedRoute
+
+Protects entire pages based on page access permissions.
+
+```tsx
+<Route path="/products" element={
+  <PermissionProtectedRoute page="products">
+    <Products />
+  </PermissionProtectedRoute>
+} />
+```
+
+### ProtectedSection
+
+Protects sections within a page based on action permissions.
+
+```tsx
+<ProtectedSection page="products" action="create">
+  <button>Add Product</button>
+</ProtectedSection>
+```
+
+### PermissionButton
+
+Button that automatically handles permissions.
+
+```tsx
+<PermissionButton 
+  page="products" 
+  action="create"
+  onClick={handleCreateProduct}
+>
+  Add Product
+</PermissionButton>
+```
+
+### SettingsSection
+
+Specific component for settings with built-in permission checks.
+
+```tsx
+<SettingsSection
+  title="System Settings"
+  description="Configure global settings"
+  permission="edit:system_settings"
+>
+  {/* Settings content */}
+</SettingsSection>
+```
+
+## Permission Hooks
+
+### usePermissions
+
+Core hook for checking any permission.
+
+```tsx
+const { hasPermission, hasPageAccess, isAdmin } = usePermissions();
+if (hasPermission('delete:products')) {
+  // Can delete products
+}
+```
+
+### usePagePermission
+
+Specialized hook for page-level permissions.
+
+```tsx
+const { canView, canCreate, canEdit, canDelete } = usePagePermission('products');
+if (canEdit()) {
+  // Can edit products
+}
+```
+
+## Database Schema
+
+Permissions are stored in the database:
+- `permissions` table: Stores all available permissions
+- `user_permissions` junction table: Maps permissions to users
+
+Admin users automatically have all permissions.
+
+## Common Permission Codes
+
+| Code | Description |
+|------|-------------|
+| `access:dashboard` | Access to Dashboard page |
+| `access:products` | Access to Products page |
+| `create:products` | Create new products |
+| `edit:products` | Edit existing products |
+| `delete:products` | Delete products |
+| `view:users` | View user accounts |
+| `edit:users` | Edit user accounts |
+| `manage:permissions` | Assign permissions to users |
+
+## Implementation Examples
+
+### Page Protection
+
+In `App.tsx`:
+```tsx
+<Route path="/products" element={
+  <PermissionProtectedRoute page="products">
+    <Products />
+  </PermissionProtectedRoute>
+} />
+```
+
+### Component Level Protection
+
+```tsx
+const { canEdit } = usePagePermission('products');
+
+function handleEdit() {
+  if (!canEdit()) {
+    toast.error("You don't have permission");
+    return;
+  }
+  // Edit logic
+}
+```
+
+### UI Element Protection
+
+```tsx
+<PermissionButton 
+  page="products" 
+  action="delete"
+  onClick={handleDelete}
+>
+  Delete
+</PermissionButton>
+```

+# Permission System Documentation
+
+This document outlines the simplified permission system implemented in the Inventory Manager application.
+
+## Permission Structure
+
+Permissions follow this naming convention:
+
+- Page access: `access:{page_name}`
+- Actions: `{action}:{resource}`
+
+Examples:
+- `access:products` - Can access the Products page
+- `create:products` - Can create new products
+- `edit:users` - Can edit user accounts
+
+## Permission Component
+
+### Protected
+
+The core component that conditionally renders content based on permissions.
+
+```tsx
+<Protected 
+  permission="create:products"
+  fallback={<p>No permission</p>}
+>
+  <button>Create Product</button>
+</Protected>
+```
+
+Options:
+- `permission`: Single permission code (e.g., "create:products")
+- `page`: Page name (checks `access:{page}` permission)
+- `resource` + `action`: Resource and action (checks `{action}:{resource}` permission)
+- `adminOnly`: For admin-only sections
+- `fallback`: Content to show if permission check fails
+
+### RequireAuth
+
+Used for basic authentication checks (is user logged in?).
+
+```tsx
+<Route element={
+  <RequireAuth>
+    <MainLayout />
+  </RequireAuth>
+}>
+  {/* Protected routes */}
+</Route>
+```
+
+## Common Permission Codes
+
+| Code | Description |
+|------|-------------|
+| `access:dashboard` | Access to Dashboard page |
+| `access:products` | Access to Products page |
+| `create:products` | Create new products |
+| `edit:products` | Edit existing products |
+| `delete:products` | Delete products |
+| `view:users` | View user accounts |
+| `edit:users` | Edit user accounts |
+| `manage:permissions` | Assign permissions to users |
+
+## Implementation Examples
+
+### Page Protection
+
+In `App.tsx`:
+```tsx
+<Route path="/products" element={
+  <Protected page="products" fallback={<Navigate to="/" />}>
+    <Products />
+  </Protected>
+} />
+```
+
+### Component Level Protection
+
+```tsx
+<Protected permission="edit:products">
+  <form>
+    {/* Form fields */}
+    <button type="submit">Save Changes</button>
+  </form>
+</Protected>
+```
+
+### Button Protection
+
+```tsx
+<Button 
+  onClick={handleDelete}
+  disabled={!hasPermission('delete:products')}
+>
+  Delete
+</Button>
+
+// With Protected component
+<Protected permission="delete:products" fallback={null}>
+  <Button onClick={handleDelete}>Delete</Button>
+</Protected>
+```
