 This package supports unicode characters including wide characters.
 
+Concurrency
+
+Many functions in this package are not thread-safe. For many applications, this
+may not be an issue: If your code makes changes in response to key events, it
+will execute in the main goroutine and thus will not cause any race conditions.
+
+If you access your primitives from other goroutines, however, you will need to
+synchronize execution. The easiest way to do this is to call
+Application.QueueUpdate() or Application.QueueUpdateDraw() (see the function
+documentation for details):
+
+  go func() {
+    app.QueueUpdateDraw(func() {
+      table.SetCellSimple(0, 0, "Foo bar")
+    })
+  }()
+
+One exception to this is the io.Writer interface implemented by TextView. You
+can safely write to a TextView from any goroutine. See the TextView
+documentation for details.
