+Delimit a rotated block of text; Kamite will de-rotate the resulting area

+
+The delimitation of a rotated block is made with three mouse clicks in
+determined spots, as shown in the following illustrations:

+![OCR rotated block reference](media/docs/rotated-ocr-reference.png)
+
+Clicks 1 and 2 must be made at the start and end of the initial edge of the text
+respectively. Click 3 can be anywhere along the closing edge (pictured as green
+above).
+
+> **Note**
+> The current implementation of rotated block OCR guesses the text orientation
+> based on the rotation. This means the feature will fail in unusual cases, such
+> as a block of horizontal text positioned vertically. The current assumption is
+> that those cases are extremely rare, but if you find use-cases where they are
+> not, please [create a GitHub Issue](https://github.com/fauu/Kamite/issues/new)
+> so that the assumption can be updated and the implementation reconsidered.
