This guide will explain how to install the `gaiad` and `gaiacli` entrypoints onto your system. With these installed on a server, you can participate in the latest testnet as either a [Full Node ](./join-testnet.md#run-a-full-node ) or a [Validator ](./validators/validator-setup.md ).

Install `go` by following the [official docs ](https://golang.org/doc/install ). Remember to set your `$GOPATH` , `$GOBIN` , and `$PATH` environment variables, for example:
```bash
mkdir -p $HOME/go/bin
echo "export GOPATH=$HOME/go" >> ~/.bash_profile
echo "export GOBIN=$GOPATH/bin" >> ~/.bash_profile
echo "export PATH=$PATH:$GOBIN" >> ~/.bash_profile
```

Next, let's install the latest version of Gaia. Here we'll use the `master` branch, which contains the latest stable release.
If necessary, make sure you `git checkout` the correct
2018-08-08 09:26:31 -07:00
[released version ](https://github.com/cosmos/cosmos-sdk/releases ).
2018-07-12 13:58:12 -07:00
```bash
mkdir -p $GOPATH/src/github.com/cosmos
cd $GOPATH/src/github.com/cosmos
git clone https://github.com/cosmos/cosmos-sdk
2018-08-08 09:26:31 -07:00
cd cosmos-sdk & & git checkout master
2018-07-12 13:58:12 -07:00
make get_tools & & make get_vendor_deps & & make install
```
2018-11-14 11:44:17 -08:00
> *NOTE*: If you have issues at this step, please check that you have the latest stable version of GO installed.
2018-07-12 13:58:12 -07:00
That will install the `gaiad` and `gaiacli` binaries. Verify that everything is OK:
```bash
$ gaiad version
$ gaiacli version
```

Now you can [join the public testnet ](./join-testnet.md ) or [create you own private testnet ](./private-testnet.md )
