+# MT4 Client Library
+
+A lightweight Go client library for interacting with a MetaTrader 4 (MT4) trading server over TCP.
+
+## Example Usage
+
+```go
+import "go.popov.link/metatrader4/mt4"
+
+client := mt4.NewClient("127.0.0.1", 443,
+    mt4.WithDialTimeout(3*time.Second),
+    mt4.WithAutoClose(true),
+)
+ctx := context.Background()
+params := map[string]string{
+    "login":    "55555",
+    "password": "_some_password_",
+}
+res, err := client.Execute(ctx, "WWAPUSER", params)
+```
+
+The `Execute` method sends a raw MT4 command. Parameters are encoded using base64 and Windows-1251.
+Use `WithAutoClose(false)` if you want to reuse the connection manually via `client.Close()`.
+
+## Options
+
+- `WithDialTimeout(d time.Duration)`: Sets the timeout for establishing a TCP connection. Default: 5s.
+- `WithReadTimeout(d time.Duration)`: Sets the maximum time to wait for a server response. Default: 5s.
+- `WithWriteTimeout(d time.Duration)`: Sets the maximum time to complete sending a request. Default: 5s.
+- `WithAutoClose(enabled bool)`: If `true`, closes the connection after each `Execute` (default). Use `false` to reuse the session manually via `client.Close()`.
+
+## Requirements
+
+- Go 1.24 or later
+- MetaTrader 4 server with TCP access
