-Go Ethereum (as its name implies) is written in [Go](https://golang.org), and as such to build from source code you need to have a Go version as recent as possible. This guide does not go into details on how to install Go itself, for that please read the [Go installation instructions](https://golang.org/doc/install).
-
-Assuming you have Go installed, you can download our project via:
-
-```shell
-go get -d github.com/ethereum/go-ethereum
-```
-
-The above command will checkout the default version of Go Ethereum into your local `GOPATH` work space, but it will not build any executables for you. To do that you can either build one specifically:
-
-    go install github.com/ethereum/go-ethereum/cmd/geth
-
-Or you can also build the entire project and install `geth` along with all developer tools by running `go install ./...` in the repository root inside your `GOPATH` work space.
-
-### Building without a Go workflow
-
-If you do not want to set up Go work spaces on your machine, only build `geth` and forget about the build process, you can clone our repository directly into a folder of your choosing and invoke `make`, which will configure everything for a temporary build and clean up after itself:
-
-    git clone https://github.com/ethereum/go-ethereum.git
-    cd go-ethereum
-    make geth
-
-This will create a `geth` (or `geth.exe` on Windows) executable file in the `go-ethereum/build/bin` folder that you can move wherever you want to run from. The binary is standalone and doesn't require any additional files.

 These commands create a `geth` executable file in the `go-ethereum/build/bin` folder that you can move wherever you want to run from. The binary is standalone and doesn't require any additional files.
 
+Additionally you can compile all additional tools go-ethereum comes with by running `make all`. A list of all tools can be found [here](https://github.com/ethereum/go-ethereum/tree/master/cmd).

 If you want to build a stable release, the v1.9.21 release for example, you can use `git checkout v1.9.21` before running `make geth` to switch to a stable branch.
