README
## 🚨 **ZGRAB 1.0 IS DEPRECATED**. Please use ZGrab 2.0: https://github.com/zmap/zgrab2.
### ZGrab 1.0: A Banner Grabber, in Go
[](https://travis-ci.org/zmap/zgrab)
[](https://goreportcard.com/report/github.com/zmap/zgrab)
## Building
You will need to have a valid `$GOPATH` set up, for more information about `$GOPATH`, see https://golang.org/doc/code.html.
Once you have a working `$GOPATH`, run:
```
go get github.com/zmap/zgrab
```
This will install zgrab under `$GOPATH/src/github.com/zmap/zgrab`
```
$ cd $GOPATH/src/github.com/zmap/zgrab
$ go build
```
