## What you'll do

In this guide you will set up a clean, reproducible **CS50x** workflow from the official documentation, verify your local configuration, and run a minimal working check so you can build with confidence.

## Prerequisites

- Access to the official documentation at [CS50x (https://cs50.harvard.edu/x/)](https://cs50.harvard.edu/x/).
- A terminal and a modern code editor such as [VS Code](/r/vscode/) or [Neovim](/r/neovim/).
- Basic familiarity with command-line navigation and version control with [Git](/r/git/).

## Step-by-step setup

1. **Verify the official source and release channel.** Open [CS50x Official Course Portal](https://cs50.harvard.edu/x/) and confirm you are reading the current stable release notes rather than outdated third-party blog posts.

2. **Initialize a minimal workspace.** Create a dedicated directory for testing CS50x in isolation before integrating it into a larger repository:

```sh title="terminal.sh"
mkdir -p ~/projects/cs50-starter
cd ~/projects/cs50-starter
git init
```

> **Tip:** Keep a small `README.md` in your starter folder recording the exact version and flags you used so future projects can copy a known-good baseline.

3. **Configure strict defaults early.** Create your baseline configuration file and commit it before adding optional plugins or third-party dependencies:

```json title="config.json"
{
  "resource": "cs50",
  "type": "course",
  "strict": true,
  "verified": "2026-10-28"
}
```

4. **Run a smoke check.** Execute the minimal build, query, or verification step described in [CS50x Official Course Portal](https://cs50.harvard.edu/x/) and confirm zero warnings in your terminal output.

> **Note:** If you are self-taught and feel shaky on pointers, memory, or how higher-level languages work under the hood, do the CS50 problem sets—do not just watch the videos.

## Common mistakes

> **Common mistake:** **Copy-pasting unpinned snippets from older tutorials.** Always check the version selector in [CS50x Official Course Portal](https://cs50.harvard.edu/x/) first. Major releases frequently simplify configuration and deprecate legacy flags.

> **Warning:** Avoid installing five companion libraries or extensions on day one. Run CS50x with its built-in defaults for a full day before adding abstractions.

## Next steps

- Bookmark [CS50x Official Course Portal](https://cs50.harvard.edu/x/) for daily API lookups.
- Return to the [CS50x resource page](/r/cs50/) to watch the curated explainers or explore paired tools.
