For further, detailed, build instruction please see the [Wiki](https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum(Go)) As of POC-8, go-ethereum uses [Godep](https://github.com/tools/godep) to manage dependencies. Assuming you have [your environment all set up](https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum(Go)), switch to the go-ethereum repository root folder, and build/install the executable you need:
Mist (GUI):
```
godep go build -v ./cmd/mist
```
Ethereum (CLI):
```
godep go build -v ./cmd/ethereum
```
Instead of `build`, you can use `install` which will also install the resulting binary.
For prerequisites and detailed build instructions please see the [Wiki](https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum(Go))
If you intend to develop on go-ethereum, check the [Developers' Guide](https://github.com/ethereum/go-ethereum/wiki/Developers'-Guide)

General command line options Command line options
============================ ============================
Both `mist` and `ethereum` can be configured via command line options, environment variables and config files.
To get the options available:
``` ```
== Shared between ethereum and Mist == ethereum -help
= Settings
-id Set the custom identifier of the client (shows up on other clients)
-port Port on which the server will accept incomming connections
-upnp Enable UPnP
-maxpeer Desired amount of peers
-rpc Start JSON RPC
-dir Data directory used to store configs and databases
= Utility
-h This
-import Import a private key
-genaddr Generates a new address and private key (destructive action)
-dump Dump a specific state of a block to stdout given the -number or -hash
-difftool Supress all output and prints VM output to stdout
-diff vm=only vm output, all=all output including state storage
Ethereum only
ethereum [options] [filename]
-js Start the JavaScript REPL
filename Load the given file and interpret as JavaScript
-m Start mining blocks
== Mist only ==
-asset_path absolute path to GUI assets directory
``` ```
For further details on options, see the [wiki](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options)

For dependency management, we use [godep](https://github.com/tools/godep). After installing with `go get github.com/tools/godep`, run `godep restore` to ensure that changes to other repositories do not break the build. To update a dependency version (for example, to include a new upstream fix), run `go get -u <foo/bar>` then `godep update <foo/...>`. To track a new dependency, add it to the project as normal than run `godep save ./...`. Changes to the Godeps folder should be manually verified then commited.

this all up and streamlines your work flow.
Coding standards
================
Sources should be formatted according to the [Go Formatting
Style](http://golang.org/doc/effective_go.html#formatting).
Unless structs fields are supposed to be directly accesible, provide
Getters and hide the fields through Go's exporting facility.
When you comment put meaningful comments. Describe in detail what you
want to achieve.
*wrong*
```go
// Check if the value at x is greater than y
if x > y {
// It's greater!
}
```
Everyone reading the source probably know what you wanted to achieve
with above code. Those are **not** meaningful comments.
While the project isn't 100% tested I want you to write tests non the
less. I haven't got time to evaluate everyone's code in detail so I
expect you to write tests for me so I don't have to test your code
manually. (If you want to contribute by just writing tests that's fine
too!)
