 To use this file browser, you need to have PHP installed on your server. You can download the PHP files and copy them to your server's directory. Then, you can access the file browser by opening the `index.php` file in your web browser.
 
+## Deploy by Docker
+
+This Dockerfile uses the official `php:7.4-apache` image as the base image, and installs the necessary PHP extensions and dependencies required to run the file browser. It then copies the contents of the current directory to the `/var/www/html/` directory in the container, which is where the Apache web server looks for files to serve.
+
+You can build a Docker image by running the `docker build` command in the same directory as the Dockerfile. For example, if you saved the Dockerfile in a directory called "my-app", you can build the Docker image by running:
+
+```
+cd my-app
+docker build -t my-app-image .
+```
+
+This will build a Docker image with the tag "my-app-image" using the Dockerfile in the current directory. You can then run a container using this image by running:
+
+When you build and run the container using this Dockerfile, the file browser should be accessible on port 80 of the container's IP address or hostname.
+
+```
+docker run -p 8080:80 my-app-image
+```
+This will start a container using the "my-app-image" image and map port 80 in the container to port 8080 on the host machine. You can then access the application in your web browser by navigating to **localhost:8080**.

 ## Usage
 
 The file browser displays the current directory path at the top of the page, and a table of files and folders with their types and sizes. You can navigate through your files and directories by clicking on the folder names. To create a new folder, enter a name in the input field and click the "Create" button. To upload a file, click the "Choose File" button and select a file from your computer, then click the "Upload" button. To rename or delete a file/folder, enter the new name (if renaming) or click the "Delete" button (if deleting), and then click the corresponding button.
