 ## Quick Start
 
+### Route 1 (recommended): use theme as Hugo module
+
+1. Install prerequisites [git](https://git-scm.com/downloads) and [go](https://go.dev/dl/) (>= 1.12)
+2. Turn your Hugo Project into a Hugo module: `hugo mod init github.com/me/my-project`
+3. Declare the `Anatole` module as a dependency of your site: `hugo mod get github.com/lxndrblz/anatole`
+4. Add the following lines at the end of your `config.toml`:
+
+```
+[module]
+  # uncomment line below for temporary local development of module
+  # replacements = "github.com/lxndrblz/anatole -> ../../anatole"
+  [[module.imports]]
+    path = "github.com/lxndrblz/anatole"
+    disable = false
+```
+### Route 2 (traditional): install theme as Git submodule
+
 1. Add the repository into your Hugo Project repository as a submodule: `git submodule add https://github.com/lxndrblz/anatole.git themes/anatole`.
-2. Configure your `config.toml`. Feel free to copy the demo `config.toml` and some content from the exampleSite.
-3. Build your site with `hugo serve` and admire the result at `http://localhost:1313/`.
