 # OBS Studio Cursor skin
-This script pack adds various cursors to be rendered inside OBS Studio.
-There are two main variations of scripts. The Python version uses common API's and requires installation of 3-rd party
-pip packages, this version is crossplatform. The Lua version uses shaders and is not crossplatform, currently Windows only.

 You are welcome to contribute. Help is needed.
 ## Developing
 There are roadmap items to choose, you are also free to suggest ideas to add and implement. There are forums and GitHub Issues check them out for suggestions or bug reports.
  [Forks](https://help.github.com/articles/fork-a-repo) are a great way to contribute to a repository.
-After forking a repository, you can send the original author a [pull request](https://help.github.com/articles/using-pull-requests)
+After forking a repository, you can send the original author a [pull request](https://help.github.com/articles/using-pull-requests) . Create a new file for each of your source/filter.
 ## Marketing 
 Write articles, reviews or tell your friends about it. The more users we have, the more people we have testing and the better we can become.
-## Design 
-Come up with some new good skins or interactive web skins, Lua shaders, and add them.
 ## Voting
-In order to improve this scripting functionality and integrate it into OBS Studio, you are encouraged to vote for this feature:
-https://ideas.obsproject.com/posts/71/option-to-highlight-mouse-cursor-and-mouse-clicks
-Currently the program lacks a way to get the position of the cursor in the texture(includes cursor wait, text, states) and is not available in the OBS Studio shader language.
