           Today I'm excited to publicly share Astro: a new kind of static site builder that delivers lightning-fast performance with a modern developer experience. To design Astro, we borrowed the best parts of our favorite tools and then added a few innovations of our own, including:
 
           - **Bring Your Own Framework (BYOF):** Build your site using React, Svelte, Vue, Preact, web components, or just plain ol' HTML + JavaScript.
-          - **100% Static HTML, No JS:** Astro strips out JavaScript from your final build and renders every page to HTML by default.
-          - **On-Demand Components:** Astro hydrates interactive components when they enter the visible page. If the user never sees it, they never load it.
+          - **100% Static HTML, No JS:** Astro renders your entire page to static HTML, removing all JavaScript from your final build by default.
+          - **On-Demand Components:** Need some JS? Astro can automatically hydrate interactive components when they become visible on the page. If the user never sees it, they never load it.
           - **Fully-Featured:** Astro supports TypeScript, Scoped CSS, CSS Modules, Sass, Tailwind, Markdown, MDX, and any of your favorite npm packages.
           - **SEO Enabled:** Automatic sitemaps, RSS feeds, pagination and collections take the pain out of SEO and syndication.
