+### startFrom
+
+If you want numbering to start from some other value than `1`, you can specify a _numbering offset_, in one of the following ways:
+
+- Specifying desired offset in `hljs.lineNumbersBlock()` call, as in:
+
+```js
+hljs.lineNumbersBlock(myCodeBlock, {
+    startFrom: 10
+});
+```
+
+- Specifying the desired offset in `data-ln-start-from` attribute of `code` element, as in:
+
+```html
+<pre>
+    <code data-ln-start-from="10">
+    ...
+    </code>
+</pre>
+```
+
+In both cases numbering offset will be `10`, meaning that the numbering will start from `10`.
+
+## Skipping some blocks
+
+(Applies to `hljs.initLineNumbersOnLoad()` initialization only.)
+
+If you want to skip some of your `code` blocks (to leave them unnumbered), you can mark them with `.nohljsln` class.
