**Welcome to the Drone codebase, we are thrilled to have you here!** 

## What is Drone?
Drone is a continuous delivery system built on container technology. Drone uses a simple YAML build file, to define and execute build pipelines inside Docker containers.

## Contributing

We encourage you to contribute to Drone! whether thats joining in on the community slack or discourse, or contributing pull requests / documentation changes or raising issues.

## Code of Conduct

Drone follows the [CNCF Code of Conduct](https://github.com/cncf/foundation/blob/master/code-of-conduct.md).

### Setup Documentation

This section of the [documentation](http://docs.drone.io/installation/) will help you install and configure the Drone Server and one or many Runners. A runner is a standalone daemon that polls the server for pending pipelines to execute.

### Usage Documentation

Our [documentation](http://docs.drone.io/getting-started/) can help you get started with the different types of pipelines/builds. There are different runners / plugins / extensions designed for different use cases to help make an efficient and simple build pipeline

### Plugin Index

Plugins are used in build steps to perform actions, eg send a message to slack or push a container to a registry. We have an extensive list of community plugins to customize your build pipeline, you can find those [here](http://plugins.drone.io/).

### Example `.drone.yml` build file. 

This build file contains a single pipeline (you can have multiple pipelines too) that builds a go application. The front end with npm. Publishes the docker container to a registry and announces the results to a slack room.

```YAML
name: default

kind: pipeline
type: docker

steps:
- name: backend
  image: golang
  commands:
    - go get
    - go build
    - go test

- name: frontend
  image: node:6
  commands:
    - npm install
    - npm test

- name: publish
  image: plugins/docker
  settings:
    repo: octocat/hello-world
    tags: [ 1, 1.1, latest ]
    registry: index.docker.io

- name: notify
  image: plugins/slack
  settings:
    channel: developers
    username: drone
```

## Building from source

We have two versions available: the [Enterprise Edition](https://github.com/drone/drone/blob/master/BUILDING) and the [Community Edition](https://github.com/drone/drone/blob/master/BUILDING_OSS)

## Release procedure

Run the changelog generator.

```BASH
docker run -it --rm -v "$(pwd)":/usr/local/src/your-app githubchangeloggenerator/github-changelog-generator -u drone -p drone -t <secret github token>
```

You can generate a token by logging into your GitHub account and going to Settings -> Personal access tokens.

Next we tag the PR's with the fixes or enhancements labels. If the PR does not fufil the requirements, do not add a label.

**Before moving on make sure to update the version file `version/version.go && version/version_test.go`.**

Run the changelog generator again with the future version according to semver.

```BASH
docker run -it --rm -v "$(pwd)":/usr/local/src/your-app githubchangeloggenerator/github-changelog-generator -u harness -p drone -t <secret token> --future-release v1.0.0
