-## Tagged template literal
-
-Chalk can be used as a [tagged template literal](https://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
-
-```js
-import chalk from 'chalk';
-
-const miles = 18;
-const calculateFeet = miles => miles * 5280;
-
-console.log(chalk`
-	There are {bold 5280 feet} in a mile.
-	In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
-`);
-```
-
-Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
-
-Template styles are chained exactly like normal Chalk styles. The following three statements are equivalent:
-
-```js
-import chalk from 'chalk';
-
-console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
-console.log(chalk.bold.rgb(10, 100, 200)`Hello!`);
-console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
-```
-
-Note that function styles (`rgb()`, `hex()`, etc.) may not contain spaces between parameters.
-
-All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
