# Installation

## Install Go

[Go 1.19+](https://golang.org/doc/install) is required.

## Install the `panacead`

If you want to install the `panacead` binary to run your node or to communicate with other nodes, please clone the `panacea-core` project and build it.

```bash
# Make sure to checkout the correct branch.
git clone -b v2.0.7-2 https://github.com/medibloc/panacea-core
cd panacea-core
make install  # All binaries are installed in $GOPATH/bin
```

Verify that the `panacead` binary is installed successfully.

```bash
$ panacead version
2.0.6
```

## Import `panacea-core` as a Go dependency

If you want to develop Go applications by importing the `panacea-core`, you cannot run `go get github.com/medibloc/panacea-core/v2` directly due to [the design of Go Modules](https://github.com/golang/go/issues/30354) , which doesn't honor `replace` directives in the `go.mod` of the `panacea-core`.

As a workaround, please add `replace` directives in your `go.mod` as below.

```
module your.com/yours

go 1.19

replace (
	github.com/cosmos/cosmos-sdk => github.com/medibloc/cosmos-sdk v0.45.12-panacea.1
	github.com/gogo/protobuf => github.com/regen-network/protobuf v1.3.3-alpha.regen.1
	github.com/tendermint/tendermint => github.com/informalsystems/tendermint v0.34.24
	google.golang.org/grpc => google.golang.org/grpc v1.33.2
)
```

Then, you can `go get` the `panacea-core`.

```bash
go get github.com/medibloc/panacea-core/v2
```
