+
+1. Install [`cargo-leptos`](/~https://github.com/leptos-rs/cargo-leptos).
+
+    ```bash
+    cargo install --locked cargo-leptos
+    ```
+
+2. Build the `envman` example:
+
+    ```bash
+    # defined in .cargo/config.toml
+    cargo envman_build_debug
+    ```
+
+3. Copy artifacts to a temporary directory:
+
+    ```bash
+    demo_dir=/tmp/demo/envman
+    test -d "${demo_dir}" || mkdir -p "${demo_dir}"
+    cp ./target/debug/envman "${demo_dir}"
+    cp ./target/web/envman/pkg "${demo_dir}"
+    ```
+
+4. Switch to the demo directory:
+
+    ```bash
+    demo_dir=/tmp/demo/envman
+    cd "${demo_dir}"
+    ```
+
+5. Make sure you have AWS credentials set up in `~/.aws/credentials`.
+
+6. Run the appropriate `envman` commands:
+
+    1. Initialize a project:
+
+        ```bash
+        # initialize a project to download from `azriel91/web_app`
+        ./envman init \
+          --type development \
+          --flow deploy \
+          demo_1 azriel91/web_app 0.1.1
+        ```
+
+    2. Status / Goal / Diff:
+
+        ```bash
+        ./envman status
+        ./envman goal
+        ./envman diff
+        ```
+
+    3. Deploy / Clean
+
+        ```bash
+        ./envman deploy
+        ./envman deploy --format json
+        ./envman deploy --format none
+
+        ./envman clean
+        ./envman clean --format json
+        ./envman clean --format none
+        ```
+
+    4. You can also interrupt the deploy/clean process.
+
+7. Run the web interface:
+
+    ```bash
+    ./envman web
+    ```
