 #### Download and Compile IPFS
 
-go-ipfs differs from the vanilla `go get` flow: it uses
-[gx](https://github.com/whyrusleeping/gx)/[gx-go](https://github.com/whyrusleeping/gx-go)
-for dependency management.
-
-First download `go-ipfs` without installing:
-
 ```
 $ go get -u -d github.com/ipfs/go-ipfs
 
 $ cd $GOPATH/src/github.com/ipfs/go-ipfs
-```
-
-Then install `go-ipfs` and its dependencies, including `gx` and `gx-go`:
-
-```
 $ make install
 ```
 
 #### Building on less common systems
 
 If your operating system isn't officially supported, but you still want to try
 building ipfs anyways (it should work fine in most cases), you can do the
-following:
+following instead of `make install`:
 
-- Install gx: `go get -u github.com/whyrusleeping/gx`
-- Install gx-go: `go get -u github.com/whyrusleeping/gx-go`
-- Fetch ipfs source: `go get -d github.com/ipfs/go-ipfs 2> /dev/null`
-- Enter source directory: `cd $GOPATH/src/github.com/ipfs/go-ipfs`
-- Install deps: `gx install`
-- Install ipfs: `go install ./cmd/ipfs`
+```
+$ make install_unsupported
+```
