 LetsEncryptCentral can be used to apply certificates for non-webserver service endpoints, it also can be used as a centralized certificate management tool for requesting and renewing Let's Encrypt certificates.
 
 ## Usage
-This project is in early development, hence not ready for production usage. Use at your own risk.
+This tool currently only supports Windows operating systems, including server systems. You can set it as a regular task every 80 days in the Windows Task Scheduler to keep your certificates updated.
 
-1. Clone this project, run the `.\Build.bat` to compile;
-1. Run the **lec.exe** from the `release` output directory;
+1. Download the latest binaries from the [releases](https://github.com/jijiechen/LetsEncryptCentral/releases);
 1. Create a new registration profile if this is your first running;
-1. Apply a certificate using your registration profile (Currently, DnsPod dynamic DNS service and Azure DNS service are supported, more DNS service providers are on the way).

 Here are the sample commands:
 
 ```powershell
-cd release
-.\lec.exe reg --accept-tos --contact user@example.com --out-reg C:\Users\MyUserName\Desktop\reg.json --out-signer C:\Users\MyUserName\Desktop\signer.key
-.\lec.exe apply name.ciznx.com -out C:\Users\MyUserName\Desktop\cert.pfx --out-type pfx --reg C:\Users\MyUserName\Desktop\reg.json --signer C:\Users\MyUserName\Desktop\signer.key --dns DnsPod --dns-conf "token_id=1234;token=822321668afcefe;domain=example.com"

+## Development plan
+Possible plans are web API/UI and Linux compatibility. Push requests to these features are warmly welcome.

 ## Contributing and license
 Pull requests are welcome. The next step is to support more dynamic DNS providers, AWS Router and Google DNS services. The future plan is wrap the core as a web service to provide out-of-box centralized certificate manageability.
