-(`<url>` argument), and the other one is by passing thread in three components:
-`<imageboard>` is a name of website (e.g. 4chan), `<board>` is a name of a board
- (e.g. wg), and `<thread>` is a number of a thread on that board.
+`<url>` -- URL of a thread.
+
+`<imageboard> <board> <thread>` -- imageboard name, board name and thread ID
+separately. E.g. `4chan b 1100500`.
