Avoid putting things in people's face before they've gotten to know you. You're not trying to be a food blog throwing pop-ups in people's faces about how they need to subscribe to your newsletter. You're trying to be a competitor to Electron.
Here's what their website tells me what they do:
> Build cross-platform desktop apps with JavaScript, HTML, and CSS
Ah! OK. I'm interested. And see how specific they are? Don't be vague. Don't say "web front-end," what do you mean? React? They then show me screenshots! Of what big companies built!
Then. They provide a Getting Started section. Not great, could be better. I want to see how it's used. But this is the bar. Be better than that bar.
Edit: Even Electron's site provides Getting Started at the end.
