-See folder `script` for the script for generating + template
+This tool extracts and formats the help text for each of the Zcash RPC calls. The output of this script is hosted at [zcash-rpc.github.io](https://zcash-rpc.github.io). 
+
+See the `script` directory for the `zcash.go` script that generates the output and template.
+
+### How to use
+
+Ensure that you have Go installed and a working and running `zcashd` instance and that the `zcash-cli` executable is available in `/usr/bin/zcash-cli` (or update the path to your zcash-cli executable in `zcash.go`). From the `script` directory simply run `go run zcash.go` and the documentation will be produced for all Zcash RPC calls and styled according to the template in `template.html`.
