+You can set a custom HSD launch command by setting the `hsd-command` key.  
+The default launch is the same as this
+```yaml
+HSD-command: {default-dir} --agent=FireWallet --index-tx --index-address --api-key {key} --prefix {Bob}
+```
+The `{default-dir}` will be replaced with the HSD directory `%appdata%\FireWallet\hsd\`.  
+The `{key}` will be replaced with the API key from the node.txt file.  
+The `{Bob}` will be replaced with the Bob wallet HSD data directory `%appdata%\Bob\hsd_data\` this is used to sync FireWallet with Bob's accounts and also stops you needing to sync the chain twice.
