 Using this library will override default behavior and configuration of create-react-app, and therefore invalidate the guarentees that come with it. Use with discretion!
 
-## Docs
+## Available plugins
 
-### addBabelPlugin(plugin, config)
+### addBabelPlugin(plugin)
 
 Adds a babel plugin. Not sure what else to say here.
 
-### addDecoratorsLegacy(config)
+### addDecoratorsLegacy()
 
 Add decorators in legacy mode. Be sure to have `@babel/plugin-proposal-decorators` installed.
 
-### disableEsLint(config)
+### disableEsLint()
 
 Does what it says. You may need this along with `addDecoratorsLegacy` in order to get decorators and exports to parse together.
 
-### addWebpackAlias(alias, config)
+### addWebpackAlias(alias)
 
 Adds the provided alias info into webpack's alias section. Pass an object literal with as many entries as you'd like, and the whole object will be merged in.
 
-### addBundleVisualizer(config)
+### addBundleVisualizer()
 
 Adds the bundle visualizer plugin to your webpack config. Be sure to have `webpack-bundle-analyzer` installed.
 
-## MobX Users
+## Using the plugins
 
-If you want CRA 2 to work with MobX, this should get you going.
+To use these plugins, import the `override` function, and call it with whatever plugins you need. Each of these plugin invocations will return a new function, that `override` will call with the newly modified config object. This means that if you need to conditionally apply any of these plugins, just provide a lambda that receives the config object, and conditionally invoke a plugin as needed, being sure to call it twice.
+
+For example
 
 ```js
-const { addDecoratorsLegacy, disableEsLint } = require("customize-cra");
+const { override, addDecoratorsLegacy, disableEsLint, addBundleVisualizer, addWebpackAlias } = require("customize-cra");
+const path = require("path");
 
-module.exports = function override(config) {
-  addDecoratorsLegacy(config);
-  disableEsLint(config);
-
-  return config;
-};
+module.exports = override(
+  addDecoratorsLegacy(),
+  disableEsLint(),
+  config => (process.env.BUNDLE_VISUALIZE == 1 ? addBundleVisualizer()(config) : config),
+  addWebpackAlias({ ["ag-grid-react$"]: path.resolve(__dirname, "src/shared/agGridWrapper.js") })
+);
 ```
+
+## MobX Users
+
+If you want CRA 2 to work with MobX, use the `addDecoratorsLegacy` and `disableEsLint`.
