 # Sharing Files
 
-::: warning
-**Note:** This page is in construction 🚧
-:::
+IronCalc makes it easy to share your files with others. Follow these steps to share a sheet and understand how sharing works.
+
+## How to Share a File
+
+1. **Click the Share Button**:  
+   In the web app, click the **"Share"** button located in the top-right corner of the interface.
+
+2. **Copy the URL**:  
+   Upon clicking, the sharing URL will be automatically copied to your clipboard.
+
+3. **Share the URL**:  
+   Paste the URL into a message, email, or browser to share it or open the sheet.
+
+## How Sharing Works
+
+- **Snapshot of the Original Sheet**:  
+   When the URL is used to open the sheet, it displays the version of the sheet that was visible when the **"Share"** button was clicked. Please note that **any changes made to the original sheet after sharing will not be reflected in the shared version**.
+
+- **Changes in the Shared Version**:  
+  Any modifications made in the shared sheet (even if it’s an existing sheet) will **not** overwrite or affect the original sheet.
+
+## Managing Sheets
+
+All your created sheets can be accessed from the **"File"** section in the top-left corner of the window. From here, you can:
+
+- View all existing sheets.
+- Delete sheets as needed.
+
+This helps you keep your files organized and makes sharing simple and straightforward.
