+## Support of testnet ##
+
+By default, Dojo is installed for running on Bitcoin mainnet.
+
+The following steps allow to install an instance of Dojo running on Bitcoin testnet.
+
+```
+# Edit the common config template file
+nano ./conf/docker-common.conf.tpl
+
+#
+# Set the value of COMMON_BTC_NETWORK to "testnet"
+#
+# Save and exit nano
+#
+```
+
+Note: This option must be set before the first installation of Dojo and mustn't be changed after this first installation.
+
+Known limitation: A single instance of Dojo can be run per machine (a same machine can't host both a mainnet and a testnet instance of Dojo).
