## Requirements
There are no dependencies except an external time series data store. For dashboards and user accounts Grafana can use an embedded
database (sqlite3) or you can use an external SQL data base like MySQL or Postgres.

## Installation
Head to [grafana.org](http://docs.grafana.org/installation/) and [download](http://grafana.org/download/)
the latest release.

If you have any problems please read the [troubleshooting guide](http://docs.grafana.org/installation/troubleshooting/).

## Documentation & Support
Be sure to read the [getting started guide](http://docs.grafana.org/guides/gettingstarted/) and the other feature guides.

## Run from master
If you want to build a package yourself, 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 1.7
- NodeJS v4+

### Get Code

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

Since imports of dependencies use the absolute path github.com/grafana/grafana within the $GOPATH,
you will need to put your version of the code in $GOPATH/src/github.com/grafana/grafana to be able
to develop and build grafana on a cloned repository. To do so, you can clone your forked repository
directly to $GOPATH/src/github.com/grafana or you can create a symbolic link from your version
of the code to $GOPATH/src/github.com/grafana/grafana. The last options makes it possible to change
easily the grafana repository you want to build.
```bash
go get github.com/*your_account*/grafana
mkdir $GOPATH/src/github.com/grafana
ln -s  $GOPATH/src/github.com/*your_account*/grafana $GOPATH/src/github.com/grafana/grafana
```

### Building the backend
```bash
cd $GOPATH/src/github.com/grafana/grafana
go run build.go setup
go run build.go build
```

### Building frontend assets

To build less to css for the frontend you will need a recent version of of **node (v4+)**,
npm (v2.5.0) and grunt (v0.4.5). Run the following:

```bash
npm install
npm run build
```

To build the frontend assets only on changes:

```bash
sudo npm install -g grunt-cli # to do only once to install grunt command line interface
grunt watch
```

### Recompile backend on source change
To rebuild on source change.
```bash
go get github.com/Unknwon/bra
bra run
```

### Running
```bash
./bin/grafana-server
```

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
