-## Plugin templates
+## Creating a new plugin or extension
 
-There are two plugin template directories inside the `/packages` directory that you can use as a reference when creating a directory for your plugin contribution. 
-Both templates are compatible with jsPsych v7+.
+After cloning this repository, run `npm install` and then `npm run new`. 
+This will prompt you through the process of creating a new plugin or extension. 
+The tool will create a new directory in the `/packages` directory with the appropriate files and names. 
 
-Regardless of which template you use, you can get started by creating a copy of the template folder in `/packages` and renaming it according to your plugin/extension name. 
-You may also want to read the jsPsych documentation on [plugin development](https://www.jspsych.org/latest/developers/plugin-development/) to understand how to work with the `index.ts`file (in `plugin-template-ts`) and `index.js` file (in `plugin-template`).
-In your plugin/extension folder, be sure that you also:
-* Edit the `package.json` file
-* Add a readme.md file to your plugin/extension directory, based on the [readme template](readme-template.md)

 This template uses TypeScript source files that are complied into JavaScript using Node.js and npm.
 This is the format used for plugins in the main jsPsych repo.
-To use this template, you should edit the `src/index.ts` file, keeping the overall structure but changing the details as appropriate (plugin name, parameters, trial method, etc.).

 You can then use the `npm run build` command to compile your `index.ts` code into JavaScript files, which will appear in a `/dist` directory.
-This format also allows you to add a Jest test file (optional), which you can create based on the `src/index.spec.ts` template file.

-### `plugin-template`

 This template allows you to put your plugin's JavaScript code directly into a JavaScript template file, rather than using TypeScript and Node.js/npm. 
 To use this template, you should keep the overall structure of the `index.js` file, but change the details as appropriate for your plugin (plugin name, parameters, etc.).
