[SixNines](https://www.sixnines.io) is a hosted service to validate
and prove availability of your web service and sites.
Read this blog post for more details:
[_SixNines.io, Your Website Availability Monitor_](http://www.yegor256.com/2017/04/25/sixnines.html).
The badge is available as:
```
https://www.sixnines.io/b/5fa8?style=flat&format=png
```
Here, the `style` parameter can be either `round` or `flat`.
The `format` parameter can be either `svg` (106x20) or `png` (424x80).
This is how you put it in your `README` (in Markdown):
```
[](https://www.sixnines.io/h/5fa8)
```
The badge you see above works exactly like that.

## How to contribute?
First, install
[Java 8+](https://java.com/en/download/),
[Maven 3.2+](https://maven.apache.org/),
[Ruby 2.3+](https://www.ruby-lang.org/en/documentation/installation/),
[Rubygems](https://rubygems.org/pages/download),
and
[Bundler](https://bundler.io/).
Then:
```bash
$ bundle update
$ bundle exec rake --quiet
```
The build has to be clean. If it's not, [submit an issue](https://github.com/zold-io/out/issues).
Then, make your changes, make sure the build is still clean,
and [submit a pull request](https://www.yegor256.com/2014/04/15/github-guidelines.html).
In order to run a single test:
```bash
$ bundle exec rake run
```
Then, in another terminal:
```bash
$ bundle exec ruby test/test_base.rb -n test_lists_flips
```
Then, if you want to test the UI, open `http://localhost:9292` in your browser,
and login, if necessary, by adding `?glogin=tester` to the URL.
