 ## Usage
 
-`dotnet run` to build and run this program. Pre-built binaries may be uploaded later.
+Go to [releases page](https://git.xeondev.com/YYHEggEgg/FireflySR.Tool.Proxy/releases) for the latest pre-built binary. It don't require any .NET versions.
+
+## Update
+
+### v2.0.0
+
+- Fixed the issue whereby the proxy has been closed by the user while the System Proxy Settings is still enabled, which may cause the user "can't access the network".  
+  Notice you may still need to change the setting if you meet a PC crash (or just start the Proxy software again and close it).
+- Updated the building .NET requirement to `8.0`; however, `PublishAot` is enabled, so the generated binaries won't require any .NET versions. You can generate AOT build by the following command:
+
+  ```sh
+  dotnet publish FireflySR.Tool.Proxy.csproj -r win-x64
+  ```
+
+  Notice a [Guardian](Guardian/Guardian.csproj) is introduced **only on Windows** and will be copied to the output directory only when the build is triggered on Windows.
+- Updated the `BlockUrls` list in `config.tmpl.json`.
