> **WARNING** the 0.4 branch is very unstable. We only recommend running this branch if you plan to dig into the codebase, troubleshoot issues and contribute (please do!). We will notify the broader community once this branch is more stable.

Drone is a Continuous Integration platform built on container technology. Every build is executed inside an ephemeral Docker container, giving developers complete control over their build environment with guaranteed isolation.

### Goals

Drone's prime directive is to help teams [ship code like GitHub](https://github.com/blog/1241-deploying-at-github#always-be-shipping). Drone is easy to install, setup and maintain and offers a powerful container-based plugin system. Drone aspires to be an industry-wide replacement for Jenkins.

### Documentation

Drone documentation is organized into several categories:

* [Setup Guide](http://readme.drone.io/docs/setup/)
* [Build Guide](http://readme.drone.io/docs/build/)
* [Plugin Guide](http://readme.drone.io/docs/plugin/)
* [API Reference](http://readme.drone.io/docs/api/)

### Community, Help

Contributions, questions, and comments are welcomed and encouraged. Drone developers hang out in the [drone/drone](https://gitter.im/drone/drone) room on gitter. We ask that you please post your questions to [gitter](https://gitter.im/drone/drone) before creating an issue.

### Cloning, Building, Running

If you are new to Go, make sure you [install](http://golang.org/doc/install) Go 1.5+ and [setup](http://golang.org/doc/code.html) your workspace (ie `$GOPATH`). Go programs use directory structure for package imports, therefore, it is very important you clone this project to the specified directory in your Go path:

```
git clone git://github.com/drone/drone.git $GOPATH/src/github.com/drone/drone
cd $GOPATH/src/github.com/drone/drone
```

Pleasure ensure your local environment has the following dependencies installed. We provide scripts in the `./contrib` folder as a convenience that can be used to install:

* libsqlite3
* sassc

Commands to build from source:

```sh
export GO15VENDOREXPERIMENT=1

make deps    # Download required dependencies
make gen     # Generate code
make build   # Build the binary
```

Commands for development:

```sh
make gen_static     # Generate static content
make gen_template   # Generate templates from amber files
make gen_migrations # Generate embedded database migrations
make vet            # Execute go vet command
make fmt            # Execute go fmt command
```

Commands to start drone:

```sh
drone
drone --debug # Debug mode enables more verbose logging
```

If you are seeing slow compile times please install the following:

```sh
go install github.com/drone/drone/Godeps/_workspace/src/github.com/mattn/go-sqlite3
```
