-## Local build
+## General Information
 
-Install dependencies:
+This documentation website is made using [Material for MkDocs](https://squidfunk.github.io/mkdocs-material/). The website structure can be found in [`mkdocs.yml`](mkdocs.yml). Build dependencies are managed with [Poetry](https://python-poetry.org/).
+
+## Local Build
+
+First you should install Poetry for dependency management. We recommend using [pipx](https://pipx.pypa.io/) or [uv](https://docs.astral.sh/uv/) to install Poetry in a dedicated virtual environment. For example, you can install Poetry by running:
 
 ```shell
+# Option 1: install via pipx
 pipx install poetry
+
+# Option 2: install via uv
+uv tool install poetry
+```
+
+After Poetry is installed, navigate to the project directory (i.e., ndn-101) and run the command below to install the required build dependencies:
+
+```shell
 poetry install
 ```
 
-Live preview:
+To start a live preview on your machine, you can run:
 
 ```shell
 poetry run mkdocs serve
 ```
+
+After running this command, the MkDocs development server should start on your local machine (default port number is 8000).
+
+To build static web pages, use this command:
+
+```shell
+poetry run mkdocs build
+```
