+## Submitting issues
+Before submitting your issue, make sure it has not been discussed earlier. You can search for existing tickets [here](https://github.com/Automattic/_s/search).
Here are some tips to consider and to help you write a great report:
* `_s` supports Internet Explorer 9 and greater, as well as the latest two versions of all other major browsers.
* `_s` is backwards compatible with the two versions prior to the current stable version of WordPress.
* `_s` uses HTML5 markup. In HTML5, it is common to use multiple `
` elements.
-* We decided to not include translations [[#50](https://github.com/Automattic/_s/pull/50)] beyond the exisiting `_s.pot` file, a RTL stylesheet [[#263](https://github.com/Automattic/_s/pull/263)], or editor styles [[#225](https://github.com/Automattic/_s/pull/225)], as they are likely to change during development of an `_s`-based theme.
