+# IPFS Integration
+
+Lotus supports making deals with data stored in IPFS, without having to re-import it into lotus.
+
+To enable this integration, open up `~/.lotus/config.toml` (Or if you manually set `LOTUS_PATH`, look under that directory) and look for the Client field, and set `UseIpfs` to `true`.
+
+```toml
+[Client]
+UseIpfs = true
+```
+
+After restarting the lotus daemon, you should be able to make deals with data in your IPFS node:
+
+```sh
+$ ipfs add -r SomeData
+QmSomeData
+$ ./lotus client deal QmSomeData t01000 0.0000000001 80000
+```
