+First, write a short **problem statement**, which _clearly_ and _briefly_ describes the problem you want to solve independently from any specific solution. It doesn't need to be long or formal, but it's difficult to consider a solution in absence of a clear understanding of the problem.

 Next, write a short **solution proposal**. How can the problem (or set of problems) you have stated above be addressed? What are the pros and cons of your approach? Again, keep it brief and informal. This isn't a specification, but rather a starting point for a conversation.

 Zed is made up of several smaller crates - let's go over those you're most likely to interact with:

- [gpui](/crates/gpui) is a GPU-accelerated UI framework which provides all of the building blocks for Zed. **We recommend familiarizing yourself with the root level GPUI documentation**
- [editor](/crates/editor) contains the core `Editor` type that drives both the code editor and all various input fields within Zed. It also handles a display layer for LSP features such as Inlay Hints or code completions.
- [project](/crates/project) manages files and navigation within the filetree. It is also Zed's side of communication with LSP.
- [workspace](/crates/workspace) handles local state serialization and groups projects together.
- [vim](/crates/vim) is a thin implementation of Vim workflow over `editor`.
- [lsp](/crates/lsp) handles communication with external LSP server.
- [language](/crates/language) drives `editor`'s understanding of language - from providing a list of symbols to the syntax map.
- [collab](/crates/collab) is the collaboration server itself, driving the collaboration features such as project sharing.
- [rpc](/crates/rpc) defines messages to be exchanged with collaboration server.
- [theme](/crates/theme) defines the theme system and provides a default theme.
- [ui](/crates/ui) is a collection of UI components and common patterns used throughout Zed.
