Don't skimp on documentation as it is crucial for technical users, poor documentation can lead to confusion among developers, increased support requests, and operational debt. Users are busy and expect clear instructions, error messages should explain how to solve the problem raised by the error, and documentation pages need to be optimized for SEO with relevant keywords, images, and alt text. Writing documentation first, while still excited about the project, can help you think through decisions, program to an interface, and write great documentation that users can figure out your product.
