+`xcaddy` - Custom Caddy Builder
-====================
+===============================
 
-This package and associated CLI tool make it easy to perform custom builds of the [Caddy Web Server](https://github.com/caddyserver/caddy).
+This command line tool and associated Go package makes it easy to make custom builds of the [Caddy Web Server](https://github.com/caddyserver/caddy).
+
+It is used heavily by Caddy plugin developers as well as anyone who wishes to make custom `caddy` binaries (with or without plugins).
 
 Supports Caddy 2 and up.

 - Go modules enabled
 
 
+## Command usage
+
+The `xcaddy` command has two primary uses:
+
+- Compile custom `caddy` binaries
+- A replacement for `go run` while developing Caddy plugins
+
+Install the `xcaddy` command with:
+
+```bash
+$ go get -u github.com/caddyserver/xcaddy/cmd/xcaddy
+```
+
+
+### Custom builds
+
+Syntax:
+
+```
+$ xcaddy build <caddy_version>
+    [--output <file>]
+    [--with <module[@version]>...]
+```
+
+- `<caddy_version>` is the core Caddy version to build (required, for now).
+- `--output` changes the output file.
+- `--with` can be used multiple times to add plugins by specifying the Go module name and optionally its version, similar to `go get`.
+
+For example:
+
+```bash
+$ xcaddy build v2.0.0-rc.1 \
+    --with github.com/caddyserver/ntlm-transport@v0.1.0
+```
+
+### For plugin development
+
+If you run `xcaddy` from within the folder of the Caddy plugin you're working on without the `build` subcommand described above, it will build Caddy with your current module and run it, as if you manually plugged it in and ran `go run`.
+
+The binary will be built and run from the current directory, then cleaned up.
+
+The current working directory must be inside an initialized Go module.
+
+Syntax:
+
+```
+$ xcaddy <args...>
+```
+- `<args...>` are passed through to the `caddy` command.
+
+For example:
+
+```bash
+$ xcaddy list-modules
+$ xcaddy run
+$ xcaddy run --config caddy.json
+```
+
+
+

-## CLI usage
-
-The CLI can be used both to make custom builds of Caddy, but also as a replacement for `go run` while developing Caddy plugins.

-### Download

-go get -u github.com/caddyserver/xcaddy/cmd/xcaddy

-### For custom builds
-
-Syntax:

-xcaddy build <version>

-- `--version` is the core Caddy version to build (required, for now).
