+# Vanilla JS Browser Wallet
 A bare-bones bitcoin wallet for the base layer implemented in vanilla javascript
+
+# Purpose
+This wallet is intended for use by JS hackers who want to add a basic bitcoin wallet to their website or chrome extension. You can copy the code from here and use it elsewhere.
+
+# Limitations
+
+The fee estimator needs some work. I wrote a spec sheet that has me create a variable that incorporates the dust limit plus some extra data depending on how many inputs a transaction has and at some point I got that variable mixed up with the dust limit itself. I need to fix that because right now this mistake causes the transaction builder to set the transaction fee higher than what you selected.
+
+When you start the wallet it is also kinda slow to display your balance and your first unused address. I use blockstream.info as a chain backend and it queries them every five seconds for a bunch of addresses -- at least 20 change addresses and 20 receive addresses (because I set a gap limit of 20) -- and when you start the wallet it won't show your balance until it's done with these queries. So be a little patient. Maybe I should add some sort of progress indicator.
