+The CI/CD is currently handled by Github Actions.
+
+The tests are run as part of every PR and for every merge to main. The codebase is built against both Mac and Linux.

+The tlaplus codebase is very complex. There are over 600k lines of code, in over 2000 files, written over 20+ years. And yet as the best distributed systems modelling tool on the market today, maintaining and improving it is critical.
 
-This overview is meant to orient new programmers as well as reorient existing ones.
+TLA+ should be regarded as a piece of mission critical software, like a cryptography library. This means that it cannot accept any kind of change that could potentially break it. Especially because being open source software means that somebody will also need to spend time fixing it.

+This chapter is meant to orient new programmers that want to navigate the codebase and start contributing, as well as reorient existing ones.

 # TLA+ Wiki intro
-Welcome to TLA+ wiki. If you find errors, or have suggestions or feedback, please create a PR or an issue.
+Welcome to TLA+ wiki. This wiki was created in response to the [2024 TLA+ community survey](http://discuss.tlapl.us/pdfW4MH5_0fKx.pdf).
+More specifically, it aims to address the following feedbacks:
+
+1. **Difficulty Understanding Existing Codebase and Documentation**: Respondents note challenges in comprehending the existing codebase and documentation. The lack of clear structure and architecture documentation, as well as the complexity of the Java codebase, pose significant obstacles for newcomers.
+2. **Navigation and Documentation**: Navigating the various TLA+ resources and finding relevant documentation is identified as a challenge. Respondents note scattered and sometimes non-existent documentation, making it difficult to find the most relevant resources and assistance.
+3. **Documentation and Tooling**: There is a strong consensus on the need for improved documentation, particularly in the form of better organised and comprehensive resources. This includes better documentation for the entire project, better release cycles for all TLA+ tools, and centralised documentation on a website rather than PDFs.
+
+
+The takeaway also sums up the mission of this wiki well:
+
+> **Streamlining Documentation**: There's a clear demand for better-organised documentation and centralised resources with a more modern interface to cater to users' preferences for accessible and comprehensive guidance.
+
+
+This is a community-backed effort, so please if you find errors or suggestions/ideas/feedback, please create a PR or an issue.
+
+If you want to contribute, please check [Contributing](contributing.md) page with detailed step by step. The source of this website is hosted [here](https://github.com/FedericoPonzi/tlaplus-wiki/).
