 # zecpaperwallet
-Zcash Sapling Paper Wallet Generator
+zecpaperwallet is a Zcash Sapling paper wallet generator that can run completely offline. You can run it on an air-gapped computer to generate your shielded z-addresses, which will allow you to keep your keys completely offline. 
+
+# Compiling
+zecpaperwallet-cli is built with rust. To compile from source, you [install Rust](https://www.rust-lang.org/tools/install). Basically, you need to just:
+`curl https://sh.rustup.rs -sSf | sh`
+
+```
+git clone https://github.com/adityapk00/zecpaperwallet.git
+cd zecpaperwallet/cli
+cargo build --release
+```
+# Generating wallets
+To generate a zcash paper wallet, simply run
+`./target/release/zecpaperwallet`
+
+You'll be asked to type some random characters that will add entropy to the random number generator. 
+
+## Saving as PDFs
+To generate a zcash paper wallet and save it as a PDF, run
+`./target/release/zecpaperwallet -z 3 --format pdf zecpaper-output.pdf`
+
+This will generate 3 shielded z-addresses and their corresponding private keys, and save them in a PDF file called `zecpaper-output.pdf`
