 `itd` is a daemon that uses my infinitime [library](https://go.arsenm.dev/infinitime) to interact with the [PineTime](https://www.pine64.org/pinetime/) running [InfiniTime](https://infinitime.io).

+### Transliteration
+
+Since the PineTime does not have enough space to store all unicode glyphs, it only stores the ASCII space and Cyrillic. Therefore, this daemon can transliterate unsupported characters into supported ones. Since some languages have different transliterations, the transliterators to be used must be specified in the config. Here are the available transliterators:
+
+- eASCII
+- Scandinavian
+- German
+- Hebrew
+- Greek
+- Russian
+- Ukranian
+- Arabic
+- Farsi
+- Polish
+- Lithuanian
+- Estonian
+- Icelandic
+- Czech
+- French
+- Armenian
+- Korean
+- Chinese
+- Romanian
+- Emoji
+
+Place the desired map names in an array as `notifs.translit.use`. They will be evaluated in order. You can also put custom transliterations in `notifs.translit.custom`. These take priority over any other maps. The `notifs.translit` config section should look like this:
+
+```toml
+[notifs.translit]
+    use = ["eASCII", "Russian", "Emoji"]
+    custom = [
+        "test", "replaced"
+    ]
+```

+
+In `cmd/itgui`, there is a gui frontend to the socket of `itd`. It uses the [fyne library](https://fyne.io/) for Go. It can be compiled by running:
