+converts from v8 coverage format to [istanbul's coverage format](https://github.com/gotwarlost/istanbul/blob/master/coverage.json.md).
+
+## Usage
+
+```js
+const v8toIstanbul = require('v8-to-istanbul')
+// the path to the original source-file is required, as its contents are
+// used during the conversion algorithm.
+const converter = v8toIstanbul('./path-to-instrumented-file.js')
+await converter.load() // this is required due to the async source-map dependency.
+// provide an array of coverage information in v8 format.
+converter.applyCoverage([
+  {
+    "functionName": "",
+    "ranges": [
+      {
+        "startOffset": 0,
+        "endOffset": 520,
+        "count": 1
+      }
+    ],
+    "isBlockCoverage": true
+  },
+  // ...
+])
+// output coverage information in a form that can
+// be consumed by Istanbul.
+console.info(JSON.stringify(converter.toIstanbul()))
+```
+
+## Ignoring Uncovered Lines
+
+Sometimes you might find yourself wanting to ignore uncovered lines
+in your application (for example, perhaps you run your tests in Linux, but
+there's code that only executes on Windows).
+
+To ignore lines, use the special comment `/* c8 ignore next */`.
+
+### ignoring the next line
+
+```js
+const myVariable = 99
+/* c8 ignore next */
+if (process.platform === 'win32') console.info('hello world')
+```
+
+### ignoring the next N lines
+
+```js
+const myVariable = 99
+/* c8 ignore next 3 */
+if (process.platform === 'win32') {
+  console.info('hello world')
+}
+```
+
+### ignoring the same line as the comment
+
+```js
+const myVariable = 99
+const os = process.platform === 'darwin' ? 'OSXy' /* c8 ignore next */ : 'Windowsy' 
+```
+
+## Testing
+
+To execute tests, simply run:
+
+```bash
+npm test
+```
