 If you prefer to run Sparrow directly from source, it can be launched with
 
-`./gradlew run`
+`./sparrow`
 
 Java 14 must be installed.
 
 ## Configuration
 
-Sparrow stores it's configuration, log file and wallets in a location appropriate to the operating system:
+Sparrow has a number of command line options, for example to change it's home folder or use testnet:
+
+```
+./sparrow -h
+
+Usage: sparrow [options]
+  Options:
+    --dir, -d
+      Path to Sparrow home folder
+    --help, -h
+      Show usage
+    --network, -n
+      Network to use
+      Possible Values: [mainnet, testnet, regtest]
+```
+
+As a fallback, the network (mainnet, testnet or regtest) can also be set using an environment variable `SPARROW_NETWORK`. For example:
+
+`export SPARROW_NETWORK=testnet`
+
+Note that if you are connecting to an Electrum server when using testnet, that server will need to running on testnet configuration as well.
+
+When not explicitly configured using the command line argument above, Sparrow stores it's mainnet config file, log file and wallets in a home folder location appropriate to the operating system:

+Testnet and regtest configurations (along with their wallets) are stored in subfolders to allow easy switching between networks.
