 ### Troubleshooting
+
 If you have previously installed IPFS before and you are running into
 problems getting a newer version to work, try deleting (or backing up somewhere
 else) your IPFS config directory (~/.ipfs by default) and rerunning `ipfs init`.
 This will reinitialize the config file to its defaults and clear out the local
 datastore of any bad entries.
