+History
+---
+
+From the beginning, AFRIM was written as a remake of [Clafrica IME](https://github.com/H-Theking/clafrica), and named *clafrica*.
+
+Then, we created an input method library with some improvements inspired from [RIME](https://github.com/rime). Later, it supports Amharic, Geez and other african phonetic input method. We renamed it to *Afrim Input Method Engine*.
+
+Inspired from [librime](https://github.com/rime/librime), we want AFRIM aka *Afrim Input Method Engine*, not only as an IME, but also as a tool/library to implement IME no matter the target language.
+
+For more details on the project name, confer the issue https://github.com/pythonbrad/afrim/issues/107.
