-:::note The Smart Rollup installer does not support the DAL
-As of today, the Smart Rollup installer does not support the DAL as a
-data availability solution. This means we will need to rely on the reveal
-channel to initialize our Smart Rollup correctly (which is not ideal for a
-decentralized file archive).
+:::note

+Currently, you cannot send the full kernel data over the data availability layer, so this tutorial relies on the reveal data channel to install the kernel as usual.
