+# ieproxy
+
+Go package to detect the proxy settings on Windows platform.
+
+The settings are initially attempted to be read from the [`WinHttpGetIEProxyConfigForCurrentUser` DLL call](https://docs.microsoft.com/en-us/windows/desktop/api/winhttp/nf-winhttp-winhttpgetieproxyconfigforcurrentuser), but falls back to the registry (`CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings`) in the event the DLL call fails.
+
+For more information, take a look at the [documentation](https://godoc.org/github.com/mattn/go-ieproxy)
+
+## Methods
+
+You can either obtain a `net/http` compatible proxy function using `ieproxy.GetProxyFunc()`, set environment variables using `ieproxy.OverrideEnvWithStaticProxy()` (though no automatic configuration is available this way), or obtain the proxy settings via `ieproxy.GetConf()`.
+
+| Method                                 | Supported configuration options:              |
+|----------------------------------------|-----------------------------------------------|
+| `ieproxy.GetProxyFunc()`               | Static, Specified script, and fully automatic |
+| `ieproxy.OverrideEnvWithStaticProxy()` | Static                                        |
+| `ieproxy.GetConf()`                    | Depends on how you use it                     |
+
+## Examples
+
+### Using GetProxyFunc():
+
+```go
+func init() {
+	http.DefaultTransport.(*http.Transport).Proxy = ieproxy.GetProxyFunc()
+}
+```
+
+GetProxyFunc acts as a middleman between `net/http` and `mattn/go-ieproxy` in order to select the correct proxy configuration based off the details supplied in the config.
+
+### Using OverrideEnvWithStaticProxy():
+
+```go
+func init() {
+	ieproxy.OverrideEnvWithStaticProxy()
+	http.DefaultTransport.(*http.Transport).Proxy = http.ProxyFromEnvironment
+}
+```
+
+OverrideEnvWithStaticProxy overrides the relevant environment variables (`HTTP_PROXY`, `HTTPS_PROXY`, `NO_PROXY`) with the **static, manually configured** proxy details typically found in the registry.
+
+### Using GetConf():
+
+```go
+func main() {
+	conf := ieproxy.GetConf()
+	//Handle proxies how you want to.
+}
+```
