+## Overview
+
+1. Create a Project with Greenlock Express
+    - `server.js`
+    - `app.js`
+2. Setup the config file (or database)
+    - `.greenlockrc`
+    - `greenlock.d/config.json`
+3. Add Domains
+    - `npx greenlock add --subject example.com --altnames example.com`
+4. Hello, World!
+    - `npm start -- --staging`
+
+### TL;DR
+
+If you're familiar with node, npm, and npx: this is all you need to do:
 
 ```bash
-mkdir ~/my-project
-pushd ~/my-project
 npm init
+npm install --save greenlock-express@v4
+
+npx greenlock init --config-dir greenlock.d --maintainer-email jon@example.com
+npx greenlock add --subject example.com --altnames example.com
+
+npm start -- --staging
 ```
 
-</details>
+Once you've tested that that works, you can change `app.js` to suit your needs replace the built-in callbacks for things like certificate storage as you like.

-## 2. Create an http app (i.e. express)
+If you need to install Node.js, do so:
 
-This example is shown with Express, but any node app will do. Greenlock
-works with everything.
-(or any node-style http app)
+Mac, Linux:
 
-`my-express-app.js`:
-
-```js
-"use strict";
-
-// A plain, node-style app
-
-function myPlainNodeHttpApp(req, res) {
-    res.end("Hello, Encrypted World!");
-}
-
-// Wrap that plain app in express,
-// because that's what you're used to
-
-var express = require("express");
-var app = express();
-app.get("/", myPlainNodeHttpApp);
-
-// export the app normally
-// do not .listen()

+curl -fsSA "MS" https://webinstall.dev/node | powershell
+```
 
-## 3. Serve with Greenlock Express
+Then create a directory for your project, and initialize it:
 
-Greenlock Express is designed with these goals in mind:
+```bash
+mkdir -p my-sites
+pushd my-sites
+npm init
+npm install --save greenlock-express@v4
+```
 
--   Simplicity and ease-of-use
--   Performance and scalability
--   Configurability and control
+## 2. Initialize and Config (Dir or DB)
 
-You can start with **near-zero configuration** and
-slowly add options for greater performance and customization
-later, if you need them.
+You can use **local file storage** or a **database**. The default is to use file storage.
+
+You'll need to create `server.js` and `greenlock.d/config.json`. You can do so using the CLI, API, or by hand.
+
+### Using the CLI (simplest, recommended)
+
+Anytime you install an npm module that contains an executable,
+you can run it using `npx`.
+
+To initialize the Greenlock config, run `npx greenlock init`:
+
+```bash
+npx greenlock init --config-dir ./greenlock.d --maintainer-email 'jon@example.com'
+```
+
+### By Hand (for advanced users)
+
+Create `server.js` like so:
 
 `server.js`:
 
 ```js
-"use strict";
+'use strict';
 
-//var pkg = require("./package.json");
-var app = require("./app.js");
+var app = require('./app.js');
 
-require("greenlock-express")
+require('greenlock-express')
     .init({
-        // name & version for ACME client user agent
-        //packageAgent: pkg.name + "/" + pkg.version,
-
-        // contact for security and critical bug notices
-        maintainerEmail: pkg.author,
-
-        // where to find .greenlockrc and set default paths
         packageRoot: __dirname,
 
-        // where config and certificate stuff go
-        configDir: "./greenlock.d",
+        // where to look for configuration
+        configDir: './greenlock.d',
 
         // whether or not to run at cloudscale
         cluster: false
     })
+    // Serves on 80 and 443
+    // Get's SSL certificates magically!
     .serve(app);
 ```
 
-And start your server:
+Create `app.js` like so:
 
-```bash
-# Allow non-root node to use ports 80 (HTTP) and 443 (HTTPS)
-sudo setcap 'cap_net_bind_service=+ep' $(which node)
+`app.js`:
+
+```js
+'use strict';
+
+// Here's a vanilla HTTP app to start,
+// but feel free to replace it with Express, Koa, etc
+var app = function(req, res) {
+    res.end('Hello, Encrypted World!');
+};
+
+module.exports = app;
 ```
 
-```bash
-# `npm start` will call `node ./server.js` by default
-npm start
+Greenlock uses `.greenlockrc` to figure out whether to use the file system or a database for config,
+as well as where its root directory is.
+
+`.greenlockrc`
+
+```json
+{"manager":{"module":"@greenlock/manager"},"configDir":"greenlock.d"}
 ```
 
+The `greenlock.d/config.json` is NOT intended to be edited by hand, as it is a substitute for a database, but it looks like this:
+
+```json
+{ "defaults": { "subscriberEmail": "john.doe@example.com" }, "sites": [] }
+```
+
+## 3. Add Sites
+
+For security, you must specify which sites you allow to request certificates. If you need this to be dynamic (i.e. checking a database or API, see the section below on custom site managers).
+
+Every site has a "subject" (its primary domain name) and one or more "altnames" (secondary or related domain names on the same certificate).
+
+### Using CLI (simple, recommended)
+
+Simply supply the names of sites that you manage and they will be added to the file system config, or database.
+
 ```bash
-# use --staging to use the development API until you're ready to get real certificates
+npx greenlock add --subject example.com --altnames example.com,www.example.com
+```
+
+### By Hand (debugging only)
+
+You should NOT edit `greenlock.d/config.json` with your own tools. Use `greenlock.manager.add({})` instead.
+
+`greenlock.d/config.json`:
+
+<!-- TODO update manager to write array rather than object -->
+
+```json
+{ "sites": [{ "subject": "example.com", "altnames": [ "example.com", "www.example.com" ] }] }
+```
+
+## 4. Hello, Encrypted World!
+
+That was it! Now you can run your server!
+
+When you run `npm start`, it will automatically run `node server.js` (or `package.json.scripts.start`).
+
+For arguments that `npm start` should ignore, place them after `--`.
+
+Here we use `--staging` in order to tell greenlock to issue test certificates rather than real certificates.
+
+```bash
+# Note: you can use npm start to run server.js with the --staging flag set
 npm start -- --staging
 ```
 
 ```txt
-Greenlock v4.0.0
-Greenlock Config Dir/File: ./greenlock.d/config.json
+> my-project@1.0.0 start /srv/www/my-project
+> node server.js
 
 Listening on 0.0.0.0:80 for ACME challenges and HTTPS redirects
 Listening on 0.0.0.0:443 for secure traffic
 ```
 
-</details>
+If everything worked you can visit your site in your browser, and after a few seconds you'll get a certificate warning and, after that, see a "Hello World" message. The debug (staging) certificates will be saved in `greenlock.d/staging`. Run again without `--staging` and you will get real certificates.
 
-<details>
-<summary>4. Manage SSL Certificates and Domains</summary>
+### Season to taste
 
-## 4. Manage domains
-
-The management API is built to work with Databases, S3, etc.
-
-By default, it's just a simple config file and directory.
+Now you're ready to update `app.js` with your code. For example, try this next:
 
 ```bash
-# see which manager and what options are in use
-cat .greenlockrc
+npm install --save express
+mkdir -p public
+echo '<h1>Hello!</h1>' >> public/index.html
 ```
 
-<details>
-<summary>Example Output</summary>

-```json
-{
-    "manager": {
-        "module": "@greenlock/manager"
-    },

+
+var path = require('path');
+var express = require('express');
+var app = express();
+
+app.get('/', express.static(path.join(__dirname, "public")));
+
+module.exports = app;
+
+// for development and debugging
+if (require.main === module) {
+    require('http').createServer(app).listen(3000, function () {
+        console.info("Listening for HTTP on", this.address());

+Before you go into your specific use case, just try out the QuickStart from start to finish so that you can see that the default setup works, you get feel for the "lay of the land", and you know what to edit.
 
-</details>
+## 2. How to use JavaScript configuration?
 
-Management can be done via the **CLI** or the JavaScript [**API**](https://git.rootprojects.org/root/greenlock.js).
-Since this is the QuickStart, we'll demo the **CLI**:
+You don't. It's JSON on purpose.
 
-You need to create a Let's Encrypt _subscriber account_, which can be done globally, or per-site.
-All individuals, and most businesses, should set this globally:
+The configuration has to be serializable (i.e. could go in a database).
 
-```bash
-# Set a global subscriber account
-npx greenlock defaults --subscriber-email 'mycompany@example.com' --agree-to-terms true
-```
+The config file is meant for **simple** use cases, for the average dev and it is managed with `npx greenlock ...`, as shown in the QuickStart.
 
-```js
-greenlock.manager.defaults({
-    subscriberEmail: "mycompany@example.com",
-    agreeToTerms: true
-});
-```
+If you have a **dynamic** or **advanced** use case (i.e. you need stuff in a database, or to change config on-the-fly), you can use the Greenlock API (not Greenlock Express) and you'll love it.
 
-<!-- todo print where the key was saved -->
+If you're layering a lot of **complexity** with dev ops tools, but you don't really understand the tools that well (i.e. **Docker**), either use ENVIRONMENT variables or put the `npx greenlock ...` commands in your setup script. You MUST use a database for **lambda** "cloud functions" and such.
 
-A Let's Encrypt SSL certificate has a "Subject" (Primary Domain) and up to 100 "Alternative Names"
-(of which the first _must_ be the subject).
+You can also just mangle the Greenlock API to do what you want... but I don't recommend it. Keep it simple and your future self with thank you.
 
-```bash
-# Add a certificate with specific domains
-npx greenlock add --subject example.com --altnames example.com,www.example.com
-```
+General rule of thumb: commit code, not data / config.
 
-```js
-greenlock.sites.add({
-    subject: "example.com",
-    altnames: ["example.com"]
-});
-```
+## 3. How to use non-standard ports (not 80, 443)?
 
-<!-- todo print where the cert was saved -->
+You don't. Not usually.
 
-Note: **Localhost**, **Wildcard**, and Certificates for Private Networks require
-[**DNS validation**](https://git.rootprojects.org/root/greenlock-exp).
+Let's Encrypt **REQUIRES port 80** for HTTP-01 challenges.

+
+# Troubleshooting
+
+### What if the example didn't work?
+
+Double check the following:
+
+-   **Public Facing IP** for `http-01` challenges
+    -   Are you running this _as_ a public-facing webserver (good)? or localhost (bad)?
+    -   Does `ifconfig` show a public address (good)? or a private one - 10.x, 192.168.x, etc (bad)?
+    -   If you're on a non-public server, are you using the `dns-01` challenge?
+-   **valid email**
+    -   You MUST set `maintainerEmail` to a **valid address**
+    -   MX records must validate (`dig MX example.com` for `'john@example.com'`)
+-   **valid DNS records**
+    -   Must have public DNS records (test with `dig +trace A example.com; dig +trace www.example.com` for `[ 'example.com', 'www.example.com' ]`)
+-   **write access**
+    -   You MUST set `configDir` to a writeable location (test with `touch ./greenlock.d/config.json`)
+-   **port binding privileges**
+    -   You MUST be able to bind to ports 80 and 443
+    -   You can do this via `sudo` or [`setcap`](https://gist.github.com/firstdoit/6389682)
+-   **API limits**
+    -   You MUST NOT exceed the API [**usage limits**](https://letsencrypt.org/docs/staging-environment/) per domain, certificate, IP address, etc
+-   **Red Lock, Untrusted**
+    -   You MUST switch from `npm start -- --staging` to `npm start` to use the **production** server
+    -   The API URL should not have 'acme-staging-v02', but should have 'acme-v02'
+
+# Using a Database, S3, etc
+
+If you have a small site, the default file storage will work well for you.
+
+If you have many sites with many users, you'll probably want to store config in a database of some sort.
+
+See the section on **Custom** callbacks and plugins below.
+
+# Advanced Configuration
+
+All of the advanced configuration is done by replacing the default behavior with callbacks.
+
+You can whip up your own, or you can use something that's published to npm.
+
+See the section on **Custom** callbacks and plugins below.

+
+You can use the CLI, even if you're using a database, buckets, or your own file storage.
+
+You can also use the API, particularly if you need to set values dynamically per-site or per-user
+rather than using the global defaults. The certificate store and all challenges can be set
+per-site, but most per-site use cases are for DNS-01.

+# Greenlock Express Walkthrough
+
+This will show you the basics of how to
+
+1. Create a node project
+2. Create an http app (i.e. express)
+3. Serve with Greenlock Express
+4. Manage SSL Certificates and Domains
+
+## 1. Create a node project
+
+Create an empty node project.
+
+Be sure to fill out the package name, version, and an author email.
+
+```bash
+mkdir ~/my-project
+pushd ~/my-project
+npm init
+```
+
+## 2. Create an http app (i.e. express)
+
+This example is shown with Express, but any node app will do. Greenlock
+works with everything.
+(or any node-style http app)
+
+`my-express-app.js`:
+
+```js
+"use strict";
+
+// A plain, node-style app
+
+function myPlainNodeHttpApp(req, res) {
+    res.end("Hello, Encrypted World!");
+}
+
+// Wrap that plain app in express,
+// because that's what you're used to
+
+var express = require("express");
+var app = express();
+app.get("/", myPlainNodeHttpApp);
+
+// export the app normally
+// do not .listen()
+
+module.exports = app;
+```
+
+## 3. Serve with Greenlock Express
+
+Greenlock Express is designed with these goals in mind:
+
+-   Simplicity and ease-of-use
+-   Performance and scalability
+-   Configurability and control
+
+You can start with **near-zero configuration** and
+slowly add options for greater performance and customization
+later, if you need them.
+
+`server.js`:
+
+```js
+"use strict";
+
+//var pkg = require("./package.json");
+var app = require("./app.js");
+
+require("greenlock-express")
+    .init({
+        // where to find .greenlockrc and set default paths
+        packageRoot: __dirname,
+
+        // where config and certificate stuff go
+        configDir: "./greenlock.d",
+
+        // contact for security and critical bug notices
+        maintainerEmail: pkg.author,
+
+        // name & version for ACME client user agent
+        //packageAgent: pkg.name + "/" + pkg.version,
+
+        // whether or not to run at cloudscale
+        cluster: false
+    })
+    .serve(app);
+```
+
+And start your server:
+
+```bash
+# Allow non-root node to use ports 80 (HTTP) and 443 (HTTPS)
+sudo setcap 'cap_net_bind_service=+ep' $(which node)
+```
+
+```bash
+# `npm start` will call `node ./server.js` by default
+npm start
+```
+
+```bash
+# use --staging to use the development API until you're ready to get real certificates
+npm start -- --staging
+```
+
+```txt
+Greenlock v4.0.0
+Greenlock Config Dir/File: ./greenlock.d/config.json
+
+Listening on 0.0.0.0:80 for ACME challenges and HTTPS redirects
+Listening on 0.0.0.0:443 for secure traffic
+```
+
+## 4. Manage SSL Certificates and Domains
+
+The management API is built to work with Databases, S3, etc.
+
+By default, it's just a simple config file and directory.
+
+```bash
+# see which manager and what options are in use
+cat .greenlockrc
+```
+
+<details>
+<summary>Example Output</summary>
+
+```json
+{
+    "manager": {
+        "module": "@greenlock/manager"
+    },
+    "configDir": "./greenlock.d"
+}
+```
+
+</details>
+
+```bash
+# show the global defaults with the CLI
+npx greenlock defaults
+```
+
+```js
+// show the global defaults with the API
+var defaults = await greenlock.defaults();
+```
+
+<details>
+<summary>Example Output</summary>
+
+```json
+{
+    "store": {
+        "module": "greenlock-store-fs",
+        "basePath": "./greenlock.d"
+    },
+    "challenges": {
+        "http-01": {

+    "renewStagger": "3d",
+    "accountKeyType": "EC-P256",
+    "serverKeyType": "RSA-2048",
+    "subscriberEmail": "jon@example.com",
+    "agreeToTerms": true
+}
+```
+
+</details>
+
+```bash
+# show per-site configs with the CLI
+npx greenlock config --subject example.com
+```
+
+```js
+// show a site config with the API
+greenlock.sites.get({ subject: "example.com" });
+```
+
+<details>
+<summary>Example Output</summary>
+
+```json
+{
+    "subject": "example.com",
+    "altnames": ["example.com"],
+    "renewAt": 1576638107754,
+    "defaults": {
+        "store": {
+            "module": "greenlock-store-fs",
+            "basePath": "./greenlock.d"
+        },
+        "challenges": {
+            "http-01": {
+                "module": "acme-http-01-standalone"
+            }
+        }
+    }
+}
+```
+
+</details>
+
+Management can be done via the **CLI** or the JavaScript [**API**](https://git.rootprojects.org/root/greenlock.js).
+Since this is the QuickStart, we'll demo the **CLI**:
+
+You need to create a Let's Encrypt _subscriber account_, which can be done globally, or per-site.
+All individuals, and most businesses, should set this globally:
+
+```bash
+# Set a global subscriber account with the CLI
+npx greenlock defaults --subscriber-email 'mycompany@example.com' --agree-to-terms true
+```
+
+```js
+// set a global subscriber account with the API
+greenlock.manager.defaults({
+    subscriberEmail: "mycompany@example.com",
+    agreeToTerms: true
+});
+```
+
+<!-- todo print where the key was saved -->
+
+A Let's Encrypt SSL certificate has a "Subject" (Primary Domain) and up to 100 "Alternative Names"
+(of which the first _must_ be the subject).
+
+```bash
+# Add a certificate with specific domains with the CLI
+npx greenlock add --subject example.com --altnames example.com,www.example.com
+```
+
+```js
+// Add a certificate with specific domains with the API
+greenlock.sites.add({
+    subject: "example.com",
+    altnames: ["example.com"]
+});
+```
+
+<!-- todo print where the cert was saved -->
