-## Launch / self-host with Docker or Podman

-Relibre ships multiple compose variants so you can choose your reverse proxy. All of them:
-- build an internal `web` container that serves the static files
-- expose a `proxy` on **localhost:8080** (HAProxy, Caddy, Apache httpd, or Nginx)
-
-**Files:**
-- `docker-compose.yml.haproxy`

+# Changelog
+
+### Migrating from v0.1.1 to v0.10.0
+
+1. `Webview.Open()` has been removed. Use other webview APIs to create a window, open a link and run main UI loop.
+2. `Webview.Debug()` and `webview.Debugf()` have been removed. Use your favorite logging library to debug webview apps.
+3. `Webview.Settings` struct has been removed. Title, URL and size are controlled via other API setters and can be updated at any time, not only when webview is created.
+4. `Webview.Loop()` has been removed. Use `Run()` instead.
+5. `WebView.Run()`, `WebView.Terminate()`, `WebView.SetTitle()`, `WebView.Dispatch()` stayed the same.
+6. `WebView.Exit()` has been renamed to `WebView.Destroy()`
+7. `WebView.SetColor()` and `WebView.SetFullScreen()` have been removed. Use `Window()` to get native window handle and probably write some Cgo code to adjust native window to your taste.
+8. `Webview.Dialog` has been removed. But it is likely to be brought back as a standalone module.
+9. `WebView.Eval()` remained the same.
+10. `WebView.InjectCSS()` has been removed. Use eval to inject style tag with CSS inside.
+11. `WebView.Bind()` kept the name, but changed the semantics. Only functions can be bound. Not the structs, like in Lorca.

+[![Go Report Card](https://goreportcard.com/badge/github.com/webview/webview_go)](https://goreportcard.com/report/github.com/webview/webview_go)
+
+Go language binding for the [webview library][webview].
+
+> [!NOTE]
+> Versions <= 0.1.1 are available in the [old repository][webview].
+
+### Getting Started
+
+See [Go package documentation][go-docs] for the Go API documentation, or simply read the source code.
+
+Start with creating a new directory structure for your project.
+
+```sh
+mkdir my-project && cd my-project
+```
+
+Create a new Go module.
+
+```sh
+go mod init example.com/app
+```
+
+Save one of the example programs into your project directory.
+
+```sh
+curl -sSLo main.go "https://raw.githubusercontent.com/webview/webview_go/master/examples/basic/main.go"
+```
+
+Install dependencies.
+
+```sh
+go get github.com/webview/webview_go
+```
+
+Build the example. On Windows, add `-ldflags="-H windowsgui"` to the command line.
+
+```sh
+go build
+```
+
+### Notes
+
+Calling `Eval()` or `Dispatch()` before `Run()` does not work because the webview instance has only been configured and not yet started.
