+npm-package-json-lint exports two main objects: `CLIEngine` and `NpmPackageJsonLint`.
+
+## NpmPackageJsonLint()
+
+Creates an instance of NpmPackageJsonLint
+
+`NpmPackageJsonLint` has one public method, `lint`. `lint` takes a package.json object in object form and a config object as parameters.
+
+### .lint(packageJsonData, configObj)
+
+Runs configured rules against the provided package.json object.
+
+#### packageJsonData
+
+Type: `Object`
+
+A package.json file in object form.
+
+#### configObj
+
+Type: `Object`
+
+A valid configuration object.
+
+#### Example
+
+The following example demostrates how to use `lint`.
+
+```js
+const {NpmPackageJsonLint} = require('npm-package-json-lint');
+
+const npmPackageJsonLint = new NpmPackageJsonLint();
+const results = npmPackageJsonLint.lint(packageJsonDataAsObject, configObject);
+```
+
+#### Return
+
+`lint` returns an object with an array of `LintIssue`s. Please see `LintIssue` section for more detail.
+
+```js
+{
+  issues: [
+    {
+      lintId: 'require-name',
+      severity: 'error',
+      node: 'name',
+      lintMessage: 'name is required'
+    }
+  ]
+}
+```
+
+### .version
+
+Calling `.version` on an instance of `NpmPackageJsonLint` will return the version number of npm-package-json-lint that the linter is associated with.
+
+#### Example
+
+```js
+const {NpmPackageJsonLint} = require('npm-package-json-lint');
+
+const npmPackageJsonLint = new NpmPackageJsonLint();
+
+npmPackageJsonLint.version;
+// => '3.0.0'
+```
+
+## CLIEngine(options)
+
+Creates an instance of CLIEngine
+
+### options
+
+Type: `Object`
+
+CLIEngine configuration object
+
+* `configFile`      {String}  Name of module/file to use.
+* `cwd`             {String}  The current working diretory for all file operations.
+* `useConfigFiles`  {Boolean} False disables use of .npmpackagejsonlintrc.json files and npmpackagejsonlint.config.js files.
+* `rules`            {Object} An object of rules to use.
+
+### Example
+
+The following example demostrates how to initialize a `CLIEngine`.
+
+```js
+const {CLIEngine} = require('npm-package-json-lint');
+
+const cliEngineOptions = {
+  configFile: '',
+  cwd: process.cwd(),
+  useConfigFiles: true,
+  rules: {}
+};
+
+const cliEngine = new CLIEngine(cliEngineOptions);
+```
+
+### .executeOnPackageJsonFiles(patterns)
+
+Runs npm-package-json-lint against the array a patterns.
+
+#### patterns
+
+Type: `Array`
+
+An array of glob patterns
+
+#### Example
+
+The following example demostrates how to use `executeOnPackageJsonFiles`.
+
+```js
+const {CLIEngine} = require('npm-package-json-lint');
+
+const cliEngineOptions = {
+  configFile: '',
+  cwd: process.cwd(),
+  useConfigFiles: true,
+  rules: {}
+};
+const patterns = ['.'];
+
+const cliEngine = new CLIEngine(cliEngineOptions);
+const results = cliEngine.executeOnPackageJsonFiles(patterns);
+```
+
+#### Return
+
+`executeOnPackageJsonFiles` returns an object with an array of results.
+
+```js
+{
+  results: [
+    {
+      filePath: './package.json',
+      issues: [
+        {
+          lintId: 'require-name',
+          severity: 'error',
+          node: 'name',
+          lintMessage: 'name is required'
+        }
+      ],
+      errorCount: 1,
+      warningCount: 0
+    }
+  ],
+  errorCount: 1,
+  warningCount: 0
+}
+```
+
+### .version
+
+Calling `.version` on an instance of `CLIEngine` will return the version number of npm-package-json-lint that the CLIEngine is associated with.
+
+#### Example
+
+```js
+const {CLIEngine} = require('npm-package-json-lint');
+
+const cliEngineOptions = {
+  configFile: '',
+  cwd: process.cwd(),
+  useConfigFiles: true,
+  rules: {}
+};
+
+const cliEngine = new CLIEngine(cliEngineOptions);
+
+cliEngine.version;
+// => '3.0.0'
+```
