 A [BIP173](https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki)/[BIP350](https://github.com/bitcoin/bips/blob/master/bip-0350.mediawiki) compatible Bech32/Bech32m encoding/decoding library.
 
 ## Example
+### Sync
 ``` javascript
-let { bech32, bech32m } = require('bech32')
+const { bech32, bech32m } = require('bech32')
 
-bech32.decode('abcdef1qpzry9x8gf2tvdw0s3jn54khce6mua7lmqqqxw')
+try {
+  bech32.decode('abcdef1qpzry9x8gf2tvdw0s3jn54khce6mua7lmqqqxw')
+  // => {
+  // 	 prefix: 'abcdef',
+  // 	 words: [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31]
+  // }
+  bech32m.decode('abcdef1l7aum6echk45nj3s0wdvt2fg8x9yrzpqzd3ryx')
+  // => {
+  // 	 prefix: 'abcdef',
+  // 	 words: [31,30,29,28,27,26,25,24,23,22,21,20,19,18,17,16,15,14,13,12,11,10,9,8,7,6,5,4,3,2,1,0]
+  // }
+  
+  // toWords etc. are available on both bech32 and bech32m objects
+  const words = bech32.toWords(Buffer.from('foobar', 'utf8'))
+  bech32.encode('foo', words)
+  // => 'foo1vehk7cnpwgry9h96'
+  bech32m.encode('foo', words)
+  // => 'foo1vehk7cnpwgkc4mqc'
+} catch (err) {
+  console.error(err)
+}
+```
+
+### Async
+``` javascript
+const { bech32, bech32m } = require('bech32')
+
+await bech32.decodeAsync('abcdef1qpzry9x8gf2tvdw0s3jn54khce6mua7lmqqqxw')
 // => {
 // 	 prefix: 'abcdef',
 // 	 words: [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31]

 // }
 
 // toWords etc. are available on both bech32 and bech32m objects
-let words = bech32.toWords(Buffer.from('foobar', 'utf8'))

 ### Advanced
 BIP173 enforces a limitation of 90 characters,  if extend the `LIMIT` parameter beyond this,  be aware that the [effectiveness of checksum decreases as the length increases](https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki#checksum-design).
