+
+## Intentions and Future Directions
+
+This repo is an intention and a notebook to study Kanji characters, that is, similar to what WaniKani intends to do.
+
+However, I am by no means intend to limit myself to Kanji taught by WaniKani, nor the readings or the associated vocabularies. Though, I am not particularly interested in learning Kanji specifically right now.
+
+I also consider stepping into fonts' territory, if I deem that necessary; for example, if [Han unification](https://en.wikipedia.org/wiki/Han_unification#Examples_of_language-dependent_glyphs) changes Kanji to an unexceptable Chinese variant.
+
+- Another case is, if the textbook form (of the Kanji) is sufficiently different from other common forms.
+- I will create a full website, if necessary to render "fonts".
+
+It is also possible that I will add Chinese contents (Hanzi) in the future.
