+## Guidelines
+
+### Add a localized layout
+
+Localized layouts (a layout specific to a language) are generally accepted.
+See for example: 4333575 (Bulgarian), 88e2175 (Latvian), 133b6ec (German).
+
+This keyboard is intended for programmers. If your language uses the Latin script, make sure it is possible to type every letters on the QWERTY keyboard.
+This is generally done using dead-keys, for example: 0bf7ff5 (Latvian), 573c13f (Swedish).
+It is also possible to add some characters that are hidden in other languages, for example 93e84ba (ß), though the space is limited.
+
+### Add a programming layout
+
+A programming layout must contains every ASCII characters as well as every dead-keys.
+Currently, the only example is QWERTY.
+
+### Translations
+
+Translations are always welcome ! See for example: 1723288 (Latvian), baf867a (French).
+The app can be translated by writing `res/values-<language code>/strings.xml` (for example `values-fr`, `values-lv`), based on the default: `res/values/strings.xml` (English).
+
+The store description is found in `metadata/android/<locale>/`, `short_description.txt` and `full_description.txt`.
+The full description changes very infrequently (it was changed once in 6 years). But if it changes too much, outdated translation might be removed.
+
+Translating changelogs is not useful because they evolve too fast. Changelogs are generally written entirely just before a release, translating them would delay releases too much. Old changelogs are not shown to anyone currently.

+Diese App ist eine virtuelle Tastatur für Android. Hauptfunktionen sind das einfache Tippen eines jeden ASCII-Zeichens durch Wischgesten, Hilfstasten, Tottasten für Akzente, sowie das Vorhandensein spezieller Tasten (Tabulator, Esc, Pfeiltasten etc.). 
+
+Die Tastatur hat bis zu vier Extrazeichen in den Ecken jeder Taste. Diese Extrazeichen werden durch das Wischen mit dem Finger auf der Taste ausgewählt.
+
+Highlights mancher Funktionen:
+
+- Jedes Zeichen und jede spezielle Taste gibt es auch auf einer PC-Tastatur. Das ist perfekt für die Nutzung von Anwendungen wie Termux.
+
+- Dies schließt auch Tab, Esc und die Pfeil- und Funktionstasten sowie Strg und Alt mit ein!
+
+- Akzenttasten sind über Tottasten verfügbar. Nach Aktivieren des Akzents kan der akzentuierte Buchstabe getippt werden. 
+
+- Sehr schlank und schnell. Braucht 500x weniger Speicherplatz als Googles Tastatur und 15x weniger als die Standardtastatur. Keine Werbung, kein Tracking.
+
+- Verschiedene Layouts: QWERTY, QWERTZ, AZERTY. Themes: Weiß, Dunkel, OLED Schwarz. Und viele weitere Optionen.
+
+Wie jede andere virtuelle Tastatur muss diese Tastatur in den Systemeinstellungen aktiviert werden. Dazu Systemeinstellungen öffnen und wie folgt vorgehen: 
+System > Sprachen und Eingabe > Bildschirmtastatur > Bildschirmtastaturen verwalten.
