+## Configure and Launch DBOS Properly
+
+Every DBOS application must create a context, register workflows and queues, then launch before running any workflows.
+
+**Incorrect (missing configuration or launch):**
+
+```go
+// No context or launch!
+func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
+	return input, nil
+}
+
+func main() {
+	// This will fail - DBOS is not initialized or launched
+	dbos.RegisterWorkflow(nil, myWorkflow) // panic: ctx cannot be nil
+}
+```
+
+**Correct (create context, register, launch):**
+
+```go
+func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
+	return input, nil
+}
+
+func main() {
+	ctx, err := dbos.NewDBOSContext(context.Background(), dbos.Config{
+		AppName:     "my-app",
+		DatabaseURL: os.Getenv("DBOS_SYSTEM_DATABASE_URL"),
+	})
+	if err != nil {
+		log.Fatal(err)
+	}
+	defer dbos.Shutdown(ctx, 30*time.Second)
+
+	dbos.RegisterWorkflow(ctx, myWorkflow)
+
+	if err := dbos.Launch(ctx); err != nil {
+		log.Fatal(err)
+	}
+
+	handle, err := dbos.RunWorkflow(ctx, myWorkflow, "hello")
+	if err != nil {
+		log.Fatal(err)
+	}
+	result, err := handle.GetResult()
+	fmt.Println(result) // "hello"
+}
+```
+
+Config fields:
+- `AppName` (required): Application identifier
+- `DatabaseURL` (required unless `SystemDBPool` is set): PostgreSQL connection string
+- `SystemDBPool`: Custom `*pgxpool.Pool` (takes precedence over `DatabaseURL`)
+- `DatabaseSchema`: Schema name (default: `"dbos"`)
+- `Logger`: Custom `*slog.Logger` (defaults to stdout)
+- `AdminServer`: Enable HTTP admin server (default: `false`)
+- `AdminServerPort`: Admin server port (default: `3001`)
+- `ApplicationVersion`: App version (auto-computed from binary hash if not set)
+- `ExecutorID`: Executor identifier (default: `"local"`)
+- `EnablePatching`: Enable code patching system (default: `false`)
