+# google-handwriting-api-elm
+
+[![built with nix](https://builtwithnix.org/badge.svg)](https://builtwithnix.org)
+
+This is a proof of concept to figure out how the google translate API works.
+It consists of a canvas which will send its data to google in order to recognize japanese letters.
+
+There are toggles which lets you filter out hiragana, katakana, etc.
+
+## Running
+
+If you have elm (and make) already installed, you can run `make` and check the target directory for outputs.
+
+However, it's preferably built with `nix build`
