I'm working with languages in R​ails, and I wonder what the best practice is when capitalizing a word.

en.yml:

```
hello: "hello"

```

application.html.erb:

```
<%= link_to t(:hello).capitalize, hello_path %> (with capitalization)
<%= link_to t(:hello), hello_path %> (without capitalization)

```

or

en.yml:

```
Hello: "Hello"
hello: "hello"

```

application.html.erb:

```
<%= link_to t(:Hello), hello_path %> (with capitalization)
<%= link_to t(:hello), hello_path %> (without capitalization)

```
