Combine water, salt, and aromatics (garlic, herbs, etc.) in a medium saucepan over high heat. Bring it to a boil. Cover and remove from heat then let it cool down completely.
Place chicken in a big enough plastic bag or bowl and pour cooled down brine over it.
Drain chicken and pat dry. Use in any recipe, but make sure the chicken gets only lightly salted once it is brined.
