 ### 安裝

-1. 設置 DNS 記錄，例如：
+1. 抓取Docker鏡像
+
+    ```shell
+    docker pull ghcr.io/yusing/go-proxy:latest
+    ```
+
+2. 建立新的目錄，並切換到該目錄，並執行
+   
+   ```shell
+    docker run --rm -v .:/setup ghcr.io/yusing/go-proxy /app/go-proxy setup
+    ```
+
+3. 設置 DNS 記錄，例如：

    - A 記錄: `*.y.z` -> `10.0.10.1`
    - AAAA 記錄: `*.y.z` -> `::ffff:a00:a01`

-2. 安裝 `go-proxy` [參見這裡](docs/docker.md)
+4. 配置 `docker-socket-proxy` 其他 Docker 節點（如有） (參見 [範例](docs/docker_socket_proxy.md)) 然後加到 `config.yml` 中

-3. 配置 `go-proxy`
+5. 大功告成，你可以做一些額外的配置
    - 使用文本編輯器 (推薦 Visual Studio Code [參見 VSCode 使用 schema](#vscode-中使用-json-schema))
-    - 或通過 `http://gp.y.z` 使用網頁配置編輯器
+    - 或通過 `http://localhost:3000` 使用網頁配置編輯器
+    - 詳情請參閱 [docker.md](docs/docker.md)

-# Adding provider support

-## Cloudflare
-
-```yaml
-autocert:
-    provider: cloudflare
-    options:
-        auth_token:
-```
-
-`auth_token` your zone API token
-
-Follow [this guide](https://cloudkul.com/blog/automcatic-renew-and-generate-ssl-on-your-website-using-lego-client/) to create a new token with `Zone.DNS` read and edit permissions
-
-## CloudDNS
-
-```yaml
-autocert:
-    provider: clouddns
-    options:
-        client_id:
-        email:
-        password:
-```
-
-## DuckDNS
-
-```yaml
-autocert:
-    provider: duckdns
-    options:
-        token:
-```
-
-Tested by [earvingad](https://github.com/earvingad)
-
-## OVHCloud
-
-```yaml
-autocert:
-    provider: ovh
-    options:
-        api_endpoint:
-        application_key:
-        application_secret:

-        oauth2_config:
-            client_id:
-            client_secret:
-```
-
-_Note, `application_key` and `oauth2_config` **CANNOT** be used together_
-
-   `api_endpoint`: Endpoint URL, or one of
-    -   `ovh-eu`,
-    -   `ovh-ca`,
-    -   `ovh-us`,
-    -   `kimsufi-eu`,
-    -   `kimsufi-ca`,

-
-## Additional setup
-
-1.  Enable HTTPs _(optional)_
-
-    Mount a folder to store obtained certs or to load existing cert
-
-    ```yaml
-    services:
-      go-proxy:
-        ...
-        volumes:
-          - ./certs:/app/certs
-    ```
-
-    To use **autocert**, complete that section in `config.yml`, e.g.
-
-    ```yaml
-    autocert:
-        email: john.doe@x.y.z # ACME Email
-        domains: # a list of domains for cert registration
-            - x.y.z
-        provider: cloudflare
-        options:
-            - auth_token: c1234565789-abcdefghijklmnopqrst # your zone API token
-    ```
-
-    To use **existing certificate**, set path for cert and key in `config.yml`, e.g.
-
-    ```yaml
-    autocert:
-        provider: local
-        cert_path: /app/certs/cert.crt
-        key_path: /app/certs/priv.key
-    ```
-
-2.  Modify `compose.yml` to fit your needs
-
-3.  Run `docker compose up -d` to start the container
-
-4.  Navigate to Web panel `http://gp.yourdomain.com` or use **Visual Studio Code (provides schema check)** to edit proxy config

-## Troubleshooting
-
-   Container not showing up in proxies list
-
-    Please check that either `ports` or label `proxy.<alias>.port` is declared, e.g.
-
-    ```yaml
-    services:
-      nginx-1: # Option 1
-        ...
-        ports:
-          - 80
-      nginx-2: # Option 2
-        ...
-        container_name: nginx-2
-        network_mode: host
-        labels:
-          proxy.nginx-2.port: 80
-    ```
-
-   Firewall issues
-
-    If you are using `ufw` with vpn that drop all inbound traffic except vpn, run below:
-
-    `sudo ufw allow from 172.16.0.0/16 to 100.64.0.0/10`
-
-    Explaination:
-
-    Docker network is usually `172.16.0.0/16`
-
-    Tailscale is used as an example, `100.64.0.0/10` will be the CIDR
-
-    You can also list CIDRs of all docker bridge networks by:
-
-    `docker network inspect $(docker network ls | awk '$3 == "bridge" { print $1}') | jq -r '.[] | .Name + " " + .IPAM.Config[0].Subnet' -`
