 Caddy 2 Development Branch
 ===========================
 
-This is the development branch for Caddy 2. This code (version 2) is not yet production-ready, but is already being used in production, and we encourage you to deploy it today on sites that are not very visible or important so that it can obtain crucial experience in the field.

This code (version 2) is not yet feature-complete or production-ready, but is already being used in production, and we encourage you to deploy it today on sites that are not very visible or important so that it can obtain crucial experience in the field.
 
 Please file issues to propose new features and report bugs, and after the bug or feature has been discussed, submit a pull request! We need your help to build this web server into what you want it to be. (Caddy 2 issues and pull requests will usually receive priority over Caddy 1 issues and pull requests.)
 
-We are looking for maintainers to represent the community! Please become involved (issues, PRs, [our forum](https://caddy.community) etc.) and express interest if you are committed to being a collaborator on the Caddy project.

 - Centralized configuration. No more disparate use of environment variables, config files (potentially multiple!), CLI flags, etc.
 - REST API. Control Caddy with HTTP requests to an administration endpoint. Changes are applied immediately and efficiently.

 - No configuration files. Except optionally to bootstrap its configuration at startup. You can still use config files if you wish, and we expect that most people will.
 - Enterprise: Export the current Caddy configuration with an API GET request.
 - Silky-smooth graceful reloads. Update the configuration up to dozens of times per second with no dropped requests and very little memory cost. Our unique graceful reload technology is lighter and faster **and works on all platforms, including Windows**.

 - Using [XDG standards](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html#variables) instead of dumping all assets in `$HOME/.caddy`.
 - Caddy plugins are now called "Caddy modules" (although the terms "plugin" and "module" may be used interchangably). Caddy modules are a concept unrelated [Go modules](https://github.com/golang/go/wiki/Modules), except that Caddy modules may be implemented by Go modules. Caddy modules are centrally-registered, properly namespaced, and generically loaded & configured, as opposed to how scattered and unorganized Caddy 1-era plugins are.
 - Modules are easier to write, since they do not have to both deserialize their own configuration from a configuration DSL and provision themselves like plugins did. Modules are initialized pre-configured and have the ability to validate the configuration and perform provisioning steps if necessary.

 ### Does Caddy 2 have telemetry?
 
-No. There was not enough academic interest to continue supporting it. If telemetry does get added later, it will not be on by default or will be vastly reduced in its scope so that it simply helps the community gain an understanding of how widely Caddy is deployed (i.e. counts of servers running, number of requests/connections handled, etc, but no actual content; just counts).

+
+## Does Caddy 2 use HTTPS by default?
+
+Yes. HTTPS is automatic and enabled by default when possible, just like in Caddy 1. Basically, if your HTTP routes specify a `host` matcher with qualifying domain names, those names will be enabled for automatic HTTPS.
+
+## I'm getting HTTPS errors with Caddy 2. The certificates aren't valid?
+
+During development, Caddy 2 uses Let's Encrypt's staging endpoint to avoid rate limit issues, so the certificates are not trusted. You can force the production endpoint if you are confident that your setup is correct and will last a while. You can add a catch-all automation policy to your `tls` app that specifies the production CA endpoint:
+
+```json
+"tls": {
+	"automation": {
+		"policies": [
+			{
+				"management": {
+					"module": "acme",
+					"ca": "https://acme-v02.api.letsencrypt.org/directory"
+				}
+			}
+		]
+	}
+}
+```
+
+## Can we get some access controls on the admin endpoint?
+
+Yeah, that's coming.
