@@ -80,6 +80,7 @@ The drone configuration was wired up as follows:
 * Generated a SSH key and put the public key part in `~/.ssh/authorize_keys`
 * Added that public key part as a "deploy key" in the abra repo (so we can do `ssh://` git remote pulls)
 * Added the private key part as a Drone secret which is available in build so that the build can SSH over to the server to run commands. That was done like so: `drone secret add --repository coop-cloud/abra --name abra_int_private_key --data @id_ed25519`
+* In order to specify a cron timing, you need to create it with the Drone CLI: `drone cron add "coop-cloud/abra" "integration" @daily --branch main`
 
 Please ask `@decentral1se` or on the Matrix channels for SSH access to the machine.
