## Automated development builds
The following builds are build automatically by our build servers after each push to the [develop ](https://github.com/ethereum/go-ethereum/tree/develop ) branch.
* [Docker ](https://registry.hub.docker.com/u/ethereum/client-go/ )
* [OS X ](http://build.ethdev.com/builds/OSX%20Go%20develop%20branch/Mist-OSX-latest.dmg )
* Ubuntu
[trusty ](https://build.ethdev.com/builds/Linux%20Go%20develop%20deb%20i386-trusty/latest/ ) |
[utopic ](https://build.ethdev.com/builds/Linux%20Go%20develop%20deb%20i386-utopic/latest/ )
* [Windows 64-bit ](https://build.ethdev.com/builds/Windows%20Go%20develop%20branch/Geth-Win64-latest.zip )

## Building the source
For prerequisites and detailed build instructions please read the
[Installation Instructions ](https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum )
on the wiki.
Building geth requires two external dependencies, Go and GMP.
You can install them using your favourite package manager.
Once the dependencies are installed, run
make geth
## Executables
Go Ethereum comes with several wrappers/executables found in
[the `cmd` directory ](https://github.com/ethereum/go-ethereum/tree/develop/cmd ):
Command | |
----------|---------|
`geth` | Ethereum CLI (ethereum command line interface client) |
`bootnode` | runs a bootstrap node for the Discovery Protocol |
`ethtest` | test tool which runs with the [tests ](https://github.com/ethereum/tests ) suite: `/path/to/test.json > ethtest --test BlockTests --stdin` .
`evm` | is a generic Ethereum Virtual Machine: `evm -code 60ff60ff -gas 10000 -price 0 -dump` . See `-h` for a detailed description. |
`disasm` | disassembles EVM code: `echo "6001" | disasm` |
`rlpdump` | prints RLP structures |
## Command line options
`geth` can be configured via command line options, environment variables and config files.
To get the options available:
geth help
For further details on options, see the [wiki ](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options )
