+tweet: AI can write docs fast, but how do you trust the code examples? Combine Claude with Hype's build-time validation — every snippet is verified before publish.
 </details>
 
 AI assistants are transforming how we write code. But when it comes to technical documentation, there's a trust problem: AI can generate plausible-looking code examples that don't actually work. Hype solves this by validating everything at build time — making AI-generated content trustworthy through automated verification.

 Hype builds and serves your blog in a single binary. That makes it a natural fit for Docker — one container that builds your site from source and serves it, with no external web server required.

 </details>
 
 Every engineering team has internal documentation. Style guides, onboarding docs, architecture decision records, runbook procedures. And almost universally, that documentation is wrong. Not because someone wrote it badly, but because the code changed and nobody updated the docs.

 Hype is a content engine that makes Markdown dynamic. You can execute code, include files, and validate everything at build time. This guide walks you through installation and your first hype document.

 </details>
 
 Release notes are the first thing users read after updating. Bad release notes — outdated examples, broken migration commands, incorrect API signatures — erode trust and generate support tickets. Hype lets you build release notes where every code example compiles, every command runs, and every API reference reflects the actual release.

+tweet: Your README says one thing, your docs site says another. Write it once with Hype and generate both from a single source.
 </details>
 
 Every open source project has the same problem: documentation lives in too many places. Your README says one thing, your docs site says another, and the install instructions in your wiki are three versions behind. You end up maintaining the same content in multiple locations, and they inevitably drift apart.

 If you've ever written training materials for a programming course, you know the pain: code examples go stale, exercises drift out of sync with the slides, and updating one module means checking every other module that references it. Hype was built to solve exactly this problem.

+# X/Twitter API Setup
+
+## 1. Create an X Developer Account
+
+1. Go to https://developer.x.com and sign in with the @hype_markdown account
+2. Sign up for the **Free** tier (1,500 tweets/month, write-only)
+3. Create a new **Project** and **App**
+
+## 2. Configure App Permissions
+
+1. In your app settings, go to **User authentication settings**
+2. Set app permissions to **Read and Write**
+3. After changing permissions, **regenerate** your Access Token and Access Token Secret (old tokens won't have the new permissions)
+
+## 3. Generate Credentials
+
+From your app's **Keys and Tokens** page, you need 4 values:
+
+| Credential | Environment Variable |
+|-----------|---------------------|
+| API Key (Consumer Key) | `X_API_KEY` |
+| API Secret (Consumer Secret) | `X_API_SECRET` |
+| Access Token | `X_ACCESS_TOKEN` |
+| Access Token Secret | `X_ACCESS_TOKEN_SECRET` |
+
+## 4. Local Setup
+
+Copy the credentials into `.envrc` at the project root:
+
+```bash
+export X_API_KEY="your-api-key"
+export X_API_SECRET="your-api-secret"
+export X_ACCESS_TOKEN="your-access-token"
+export X_ACCESS_TOKEN_SECRET="your-access-token-secret"
+```
+
+Then activate with direnv:
+
+```bash
+direnv allow
+```
+
+Test with a dry run:
+
+```bash
+make tweet-dry SLUG=getting-started
+```
+
+## 5. CI Setup (GitHub Actions)
+
+Set the repository secrets using the `gh` CLI:
+
+```bash
+gh secret set X_API_KEY --body "your-api-key"
+gh secret set X_API_SECRET --body "your-api-secret"
+gh secret set X_ACCESS_TOKEN --body "your-access-token"
+gh secret set X_ACCESS_TOKEN_SECRET --body "your-access-token-secret"
+```
+
+Once set, the `tweet.yml` workflow will automatically tweet when blog posts with a `tweet` field are merged to main.
+
+## 6. Manual Tweeting
+
+To tweet an existing post manually:
+
+```bash
+make tweet SLUG=getting-started
+```
+
+To preview without posting:
+
+```bash
+make tweet-dry SLUG=getting-started
+```
+
+## Adding Tweets to Blog Posts
+
+Add a `tweet` field to the `<details>` frontmatter block in any blog post:
+
+```markdown
+<details>
+slug: my-article
+published: 03/16/2026
+author: Gopher Guides
+seo_description: Full SEO description here
+tags: tutorial, hype
+tweet: Short punchy text for X (max ~250 chars, URL is appended automatically)
+</details>
+```
+
+The script automatically appends the post URL, so keep the tweet text under ~250 characters.
