- You need to install the Ledger Monero app and configure your system. Instructions can be found [here](https://github.com/LedgerHQ/blue-app-monero/blob/master/doc/user/bolos-app-monero.pdf) (sections 3.1.1 and 3.2.1 in particular). In addition, make sure to set the network to `Mainnet`
- We'd strongly advise to test the full process first. That is, send a small amount to the wallet and subsequently restore it (using aforementioned guide) to verify that you can recover the wallet. Note that, upon recreating / restoring the wallet, you ought to append the `--restore-height` flag (with a block height before the height of your first transaction to the wallet) to the command in step 3 (Windows), step 5 (Mac OS X), or step 3 (Linux). More information about the restore height and how to approximate it can be found [here](https://monero.stackexchange.com/questions/7581/what-is-the-relevance-of-the-restore-height).
- If desired, you can manually tweak the `--subaddress-lookahead` value. The first value is the number of accounts and the second value is the number of subaddresses per account. Thus, if you, for instance, want to pregenerate 5 accounts with 100 subaddresses each, use `--subaddress-lookahead 5:100`. Bear in mind that, the more subaddresses you pregenerate, the longer it takes for the Ledger to create your wallet.
You only have to use the `--generate-from-device` flag once (i.e. upon wallet creation). Thereafter, you'd basically use it similar to how you normally use the CLI. That is:
