 First of all, you must have a docker environment, if not you should [install docker](https://docs.docker.com/engine/install/) first. After completion, use the following command to start *AllTube*.
 
-```
-# add `-e TITLE=...` option can specify the website title
-shell> docker run -dit -p 24488:80 --name alltube dnomd343/alltube
+```bash
+docker run -d --restart always --name alltube -p 24488:80 dnomd343/alltube
 ```
 
-If necessary, you can use the following command to build the image yourself.
+After the command is run, *Alltube* will work on `tcp/24488`, of course, this port can be arbitrary. We can also specify the working options of *Alltube* through environment variables, the following are built-in options.
 
-```
-shell> docker build -t alltube https://github.com/dnomd343/alltube_docker.git
++ `TITLE=...` ：Specify the website title.
+
++ `REMUX=ON` ：Merge best audio and best video.
+
++ `STREAM=ON` ：Allow stream videos through server.
+
++ `CONVERT=ON` ：Enabled audio conversion.
+
+Here is an example:
+
+```bash
+docker run -d --restart always --name alltube \
+  --env TITLE="My Alltube Site" \
+  --env CONVERT=ON \
+  --env STREAM=ON \
+  --env REMUX=ON \
+  -p 24488:80 dnomd343/alltube
 ```
 
 Next, configure your web server reverse proxy to `localhost:24488`, let's take *Nginx* as an example here.
 
-```
+```nginx
 server {
     listen 80;
-    server_name video.343.re; # your domain
+    server_name video.343.re;  # your domain
     return 301 https://$server_name$request_uri;
 }
 
 server {
     listen 443 ssl http2;
-    server_name video.343.re; # your domain
-    ssl_certificate /etc/ssl/certs/343.re/fullchain.pem; # TLS certificate of your domain
-    ssl_certificate_key /etc/ssl/certs/343.re/privkey.pem; # TLS private key of your domain
+    server_name video.343.re;  # your domain
+    ssl_certificate /etc/ssl/certs/343.re/fullchain.pem;  # TLS certificate of your domain
+    ssl_certificate_key /etc/ssl/certs/343.re/privkey.pem;  # TLS private key of your domain
     location / {
-        proxy_set_header Host $http_host;
         proxy_pass http://127.0.0.1:24488;
+        proxy_set_header Host $http_host;
+        proxy_set_header X-Forwarded-Proto $scheme;
     }
 }
 ```
 
-Finally, use the `nginx -s reload` command to take effect, visit your domain name and enjoy it !

+If necessary, you can use the following command to build the image yourself.
+
+```bash
+docker build -t alltube https://github.com/dnomd343/alltube-docker.git
+```
+
+Due to the stagnation of the [youtube-dl](https://github.com/ytdl-org/youtube-dl) update, currently we use the [yt-dlp](https://github.com/yt-dlp/yt-dlp) project, you can manually change `YTDLP` in the Dockerfile to specify the latest version.
+
+If you don't need the conversion function, you can remove the installation of `ffmpeg`, which will reduce the image size to a certain extent.
+
+In addition, the project supports multi-stage builds, using the `buildx` command will speed up the build process.
