+
+This repo is a port of Wanikani's JS implementation located [here](https://github.com/WaniKani/WanaKana).
+
+No errors are returned by any of the exported functions or methods; this is to keep the behavior the same as the original implementation, but there is an argument to be made to change this.
+
+## Improvements
+If anyone would like to make a PR to improve this repository, here are a few suggestions regarding what could be done:
+[] Improve tree caching -- currently only one tree can be stored in the cache and it is not modifiable
+[] Add a wasm compilation target and add support for binding and unbinding an element similar to what the original implementation is capable of
+[] Move the tree generation logic into a `generate` package. Running `go generate` should generate source code with the `go:embed` directive along with all of the key/value pairs to store in the tree. This makes it more transparent as to what each tree contains by default rather than having to decipher how it is being generated.
+
+## Usage
+Here is an example of how this package can be used:
+``` go
+package main
+
+import (
+	"fmt"
+
+	"github.com/deelawn/wanakana"
+	"github.com/deelawn/wanakana/config"
+)
+
+func main() {
+
+	romaji := "okonomiyakinikuman"
+	options := config.Options{
+		IMEMode: config.ToKanaMethodKatakana,
+	}
+
+	kana := wanakana.ToKana(romaji, options, nil)
+
+	fmt.Println(kana)
+}
+
+```
+
+This produces `オコノミヤキニクマン`
