+# jest-changed-files
+
+A module used internally by Jest to check which files have changed since you last committed in git or hg.
+
+## Install
+
+```sh
+$ npm install --save jest-changed-files
+```
+
+## API
+
+### `getChangedFilesForRoots(roots: <Array<string>>, options: ?object): Promise<?object>`
+
+Get the list of files and repos that have changed since the last commit.
+
+#### Parameters
+
+roots: Array of string paths gathered from [jest roots](https://jestjs.io/docs/configuration#roots-arraystring).
+
+options: Object literal with keys
+
+- lastCommit: boolean
+- withAncestor: boolean
+
+### findRepos(roots: <Array<string>>): Promise<?object>
+
+Get a set of git and hg repositories.
+
+#### Parameters
+
+roots: Array of string paths gathered from [jest roots](https://jestjs.io/docs/configuration#roots-arraystring).
+
+## Usage
+
+```javascript
+import {getChangedFilesForRoots} from 'jest-changed-files';
+
+getChangedFilesForRoots(['/path/to/test'], {
+  lastCommit: true,
+  withAncestor: true,
+}).then(files => {
+  /*
+  {
+    repos: [],
+    changedFiles: []
+  }
+  */
+});
+```
+
+```javascript
+import {findRepos} from 'jest-changed-files';
+
+findRepos(['/path/to/test']).then(repos => {
+  /*
+  {
+    git: Set<Path>,
+    hg: Set<Path>
+  }
+  */
+});
+```
