-#### Updating using ipfs-update
 IPFS has an updating tool that can be accessed through `ipfs update`. The tool is
 not installed alongside IPFS in order to keep that logic independent of the main
 codebase. To install `ipfs update`, [download it here](https://ipfs.io/ipns/dist.ipfs.io/#ipfs-update).
 
 #### Downloading IPFS builds using IPFS
+
 List the available versions of go-ipfs:
+
 ```
 $ ipfs cat /ipns/dist.ipfs.io/go-ipfs/versions
 ```
 
 Then, to view available builds for a version from the previous command ($VERSION):
+
 ```
 $ ipfs ls /ipns/dist.ipfs.io/go-ipfs/$VERSION
 ```
 
 To download a given build of a version:
+
 ```
 $ ipfs get /ipns/dist.ipfs.io/go-ipfs/$VERSION/go-ipfs_$VERSION_darwin-386.tar.gz # darwin 32-bit build

+Description: Dotted means "likely going away". The "Legacy" parts are thin wrappers around some commands to translate between the new system and the old system. The grayed-out parts on the "daemon" diagram are there to show that the code is all the same, it's just that we turn some pieces on and some pieces off depending on whether we're running on the client or the server.
