-# Roadmap
-Getting to all the 523 tests Puppeteer has, will be a long and fun journey. So, this will be the roadmap for Puppeteer Sharp 1.0:
-
-## 0.1 First Minimum Viable Product
-The first 0.1 will include:
-* Browser download
-* Basic browser operations: create a browser, a page and navigate a page.
-* Take screenshots.
-* Print to PDF.
-
-## 0.2 Repository cleanup
-This version won't include a new version. It will be about improving the repository:
-
-* Setup CI.
-* Create basic documentation (Readme, contributing, code of conduct).
-
-## 0.3 Puppeteer
-It will implement all [Puppeteer related tests](https://github.com/GoogleChrome/puppeteer/blob/master/test/test.js#L108).
-
-## 0.4 Page
-It will implement all Page tests except the ones testing the evaluate method.
-As this will be quite a big version, I think we will publish many 0.3.X versions before 0.4.
-
-## 0.5 Frames
-It will implement all Frame tests.
-
-## 0.6 Simple interactions
-It will implement all tests related to setting values to inputs and clicking on elements.
-
-## 0.7 Page Improvements
-It will implement all missing Page tests.
-
-## 0.8 Element Handle and JS Handle
-It will implement all tests releated to Element handles and JS handles.
-
-## 0.X Intermediate versions
-At this point, We will have implemented most features, except the ones which are javascript related.
-I believe there will be many versions between 0.6 and 1.0.
-
-## 1.0 Puppeteer the world!
-The 1.0 version will have all (or most) Puppeteer features implemented. I don't know if we'll be able to cover 100% of Puppeteer features, due to differences between both technologies, but we'll do our best.
