 ## Find an address
-
+- `xpub`: the account extended public key
-Edit `find-address.js` and fill in these fields:
+- `address`: the address to search for
-
+- `start`: the starting index (default: 0)
-- `ACCOUNT_XPUB`: the account extended public key
+- `end`: the ending index (default: 0x7fffffff)
-- `SEARCH_ADDRESS`: the address to search for
 
 
 ```bash
-node find-address.js
+node find-address.js --xpub your-xpub-key --address address-to-search-for
 ```
 
 ## Generate addresses
+- `xpub`: the account extended public key
+- `number`: the number of addresses to generate (default: 1000)
+- `start`: the starting index (default: 0)
+- `change`: toggle to display change addresses (default: false)
 
-Edit `generate-address.js` and fill in these fields:
-
-- `ACCOUNT_XPUB`: the account extended public key
-- `START`: the starting index
-- `END`: the ending index
 
+Generate the first 1000 addresses.
 ```bash
-node generate-address.js
+node generate-address.js --xpub your-xpub-key --number 1000
 ```
+
+Generate addresses from 1000 to 1010 and display change addresses.
+```bash
+node generate-address.js --xpub your-xpub-key --number 10 --start 1000 --change
+```
+
 Probably best to save the output to a file.
 ```bash
-node generate-address.js > addresses.txt
+node generate-address.js --xpub your-xpub-key > addresses.txt
 ```
