-## Which challenges does the project address?
+> **Note**: Tuttle is currently in development. The current version is a prototype, not quite ready for production use. However, we are happy to receive feedback from testers.
+
+## Mission Statement
 
 The working world is changing, the trend is towards freelancing: software developers, designers and journalists appreciate the freedom and creative possibilities of solo self-employment. More and more professionals are choosing it for themselves. It allows them to specialize and gain experience with many projects and clients.
 
 With freelancing, there are many side activities: Marketing, client communication, legal and financial planning - although the latter probably appeals to few solo self-employed people. But what if software could make financial planning in freelancing almost as easy as being an employee? Our tool minimizes risks and makes the financial part of the job easy. Freelancing becomes more efficient, less risky, and therefore more beginner-friendly.
 
-## How are you tackling the problem?
-
 With Tuttle, we are developing a financial planning tool that is tailored to the needs of solo freelancers. We automate and give freelancers more time to do the work they love.
 The application provides analysis and forecasting functions on income, expenses, disposable income, uncertainty management or explainability of the forecast and convinces with portability, among other things.
 
-We develop the solution as a desktop application. Sensitive financial data is processed locally on the end device without central data collection. For data analysis, we rely on open source tools from the Python ecosystem.

-## What is the product vision?
-
-Desktop apps are great - let's have more of them. We are consciously developing a desktop app with local data storage, not a web app, since your business data is none of our business.
