+ntext = { git = "https://github.com/uttarayan21/ntext" }
+```
+
+Example program
+
+```rust
+extern crate ntext;
+use ntext::to_text;
+fn main() {
+    println!("{}",to_text(12345));
+}
+```
+
+which should output  
+`twelvethousandthreehundredfortyfive`
+
+I will probably add formatting the text later
