 # AutoSSL
+
+AutoSSL is an open-source project built on top of acme.sh, designed to provide an SSL certificate distribution service. With AutoSSL, you can generate SSL certificates on one server and distribute them to other servers via HTTP. This project is inspired by the [vx.link](https://vx.link) SSL certificate service.
+
+## Features
+
+- **Centralized SSL Certificate Generation**: Generate SSL certificates on a single server.
+- **HTTP Distribution**: Distribute the generated certificates to other servers via HTTP.
+- **DNS Alias Mode**: Uses DNS alias mode for certificate generation. Please refer to the [acme.sh documentation](https://github.com/acmesh-official/acme.sh/wiki/DNS-alias-mode) for more details.
+
+## Getting Started
+
+### Prerequisites
+
+- Docker
+- Docker Compose
+
+### Installation
+
+Create a `docker-compose.yml` file with the following content:
+
+```yaml
+version: '3.7'
+services:

+      - ACME_EMAIL=example@gmail.com
+      - ACME_DNS=dns_cf
+      - ACME_ALIAS=alias.com
+      - CF_Zone_ID=xxxxxxxx
+      - CF_Token=xxxxxx
+
+volumes:
+  acme:
+  data:
+```
+
+Run the following command to start the service:
+```sh
