+# It expects the following environment variables to be set except where noted:
+#
+# STORAGE_PATH - The path where the node's data will be stored
+# NODE_CONFIG_PATH - The path to the node's configuration file
+# GENESIS_PATH (optional) - The path to the genesis block
+# GENESIS_BUCKET (optional) - The S3 bucket where the genesis block is stored.
+# GENESIS_ENV (optional) - The target environment. Used for fetching the genesis block from S3.
+# GENESIS_FUND (optional) - The fund name. Used for fetching the genesis block from S3.
+# GENESIS_VERSION (optional) - The genesis version. Used for fetching the genesis block from S3. If not set, the "default" version will be used.
+# BFT_PATH (optional) - The path to the BFT file. Only used by leader nodes.
+# LEADER (optional) - If set, the node will be configured as a leader node.
+# DEBUG_SLEEP (optional) - If set, the script will sleep for the specified number of seconds before starting the node.
