Trying to add a new key "key" and a value. 

I know about the YAML lib and looping, but I dont know how ot manipulate an array of hashes. 

What I currently have:

```ruby
#!/usr/bin/env ruby

require 'yaml'

yaml_string = File.read "./_data/tools.yml"
tools = YAML.load yaml_string

tools.map do |tool|
  tool.store("key", tool["name"].downcase)
end

File.open("./_data/tools.yml", "w") {|file| file.write(tools) }
```

You'll need to do something like this:

require 'yaml'

yaml_string = File.read "./tools.yaml"
tools = YAML.load yaml_string

tools.map do |tool|
  tool["key"] = "key"
end

See: https://repl.it/repls/WirelessJubilantDecimal

@itszaga.. I updated the gist and what I have works in that it adds the key and value. Like I mentioned in the tweet, its writing to the file with the hash, instead of yaml, so im trying to figure that one out.

Change your last line to File.open("./_data/tools.yml", "w") { |file| file.write(tools.to_yaml) }

@itszaga yooo that worked! Thank you so much!
