+# 02 — Creating a repository
+
+🌍 **English** · [Türkçe](../../tr/02-create-repository/readme.md) · [Deutsch](../../de/02-create-repository/readme.md) · [Français](../../fr/02-create-repository/readme.md) · [Русский](../../ru/02-create-repository/readme.md)
+
+A repository is one project. Create one per project, not one per file.
+
+## Steps
+
+1. Press **+** at the top right → **New Repository**.
+2. **Owner** — yourself, or an organisation you belong to.
+3. **Repository name** — lowercase, no spaces: `network-lab`, `web-site`, `guide`.
+4. **Description** — one line explaining what it is. It appears in search results.
+5. **Visibility**
+   - *Public* — anyone who can reach the server can read it.
+   - *Private* — only you and the people you invite.
+6. **Initialize repository** — tick it. This creates the first commit with a `README.md`, so the repository is usable straight away.
+7. Press **Create Repository**.
+
+## Good names
+
+| Instead of | Prefer |
+|-----------|--------|
+| `Yeni Proje (son)` | `yeni-proje` |
+| `Ağ Ödevi 1` | `network-lab-01` |
+| `test test 2` | `packet-tracer-tests` |
+
+Spaces and brackets in names make links harder to share and can confuse relative paths inside documents. Lowercase letters, digits and hyphens are always safe.
+
+## After creation
+
+- **Settings → Collaborators** — give other people read or write access.
+- **Settings → Branches** — protect `main` so nobody commits to it directly.
+- **Add File** — start filling the repository (chapter 03).
+
+## Deleting a repository
+
+**Settings → Danger Zone → Delete this repository.** You must type the repository name to confirm. This cannot be undone — the history goes with it.
