## Run from master
If you want to build a package your self, or contribute. Here is a guide for how to do that. You can always find
the latest master builds [here](http://grafana.org/download/builds)

### Dependencies

- Go 1.4
- NodeJS

### Get Code

```
go get github.com/grafana/grafana
```

### Building the backend
```
cd $GOPATH/src/github.com/grafana/grafana
go run build.go setup            (only needed once to install godep)
godep restore                    (will pull down all golang lib dependecies in your current GOPATH)
go build .
```

### Building frontend assets

To build less to css for the frontend you will need a recent version of of node (v0.12.0),
npm (v2.5.0) and grunt (v0.4.5). Run the following:

```
npm install
npm install -g grunt-cli
grunt
```

### Recompile backend on source change
To rebuild on source change (requires that you executed godep restore)
```
go get github.com/Unknwon/bra
bra run
```

### Running
```
./grafana
```

Open grafana in your browser (default http://localhost:3000) and login with admin user (default user/pass = admin/admin).

### Dev config

Create a custom.ini in the conf directory to override default configuration options.
You only need to add the options you want to override. Config files are applied in the order of:

1. grafana.ini
2. dev.ini (if found)
3. custom.ini
