+The external full node must be configured for the support of Dojo. Edit the bitcoin.conf file of your external full node and check that the following lines are properly initialized.

+# Force bitcoind to index all the transactions

+
+# Check that bitcoind accepts connections from 127.0.0.1 (linux)
+# or from the IP address of the Docker Virtual Machine (MacOS, Windows)

+# Check that a port is defined for the RPC API (or 8332 will be used as default value)

+### Fast import of block headers in Dojo (optional) ###
+
+When Dojo is installed for the first time, the Tracker imports the block headers in the database.
 
-# Start the installation of your Dojo
+Follow these steps if you want to speed up this operation by preloading an archive of the block headers.
+
+```
+# Download the archive [https://samouraiwallet.com/static/share/2_blocks.sql.gz](https://samouraiwallet.com/static/share/2_blocks.sql.gz) to the "<dojo_dir>/db-scripts/" directory. Don't modify the name of the archive.
