 ## 2. Building the full IDE
 
-Beyond the extension, we very occasionally edit the IDE when we need to access more functionality. If you want to work on the full IDE, please follow the steps below, or see VS Code's full [how to contribute](https://github.com/microsoft/vscode/wiki/How-to-Contribute) page.

Also feel free to submit an issue or get in touch with us with any build errors.
 
-Before starting, make sure you've built the extension (by running `cd .\extensions\void\` and `npm run build`).
+<!-- TODO say whether you can build each distribution on any Operating System, or if you need to build Windows on Windows, etc -->
 
-Make sure you're on the correct NodeJS version as per `.nvmrc`.

+
+If you're using a Mac, make sure you have Python and XCode installed (you probably do by default).
+
+### b. Build Prerequisites - Windows
+
+If you're using a Windows computer, first get [Visual Studio 2022](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=Community) (recommended) or [VS Build Tools](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools) (not recommended). If you already have both, you might need to run the next few steps on both of them.
+
+Find the box for Visual Studio 2022 (or VS Build Tools) and click Install/Modify.
+
+Under Workloads, select "Desktop development with C++" and "Node.js build tools".
+
+Under Individual components, select every item under:
+
+- `MSVC v143 - VS 2022 C++ x64/x86 Spectre-mitigated libs (Latest)`,

+
+### Build instructions
+
+Before building Void, please follow the prerequisite steps above for your operating system. Also make sure you've already built and compiled the Void extension (or just run `cd ./extensions/void && npm install && npm run build && npm run compile && cd ../..`).
+
+To build Void, first open `void/` in VSCode. Then:

 ## Roadmap
 
-Here are the most important topics on our Roadmap. More ⭐'s = more important.
-
-## ⭐⭐⭐ Improve diffs.
-
-We define a "diff" as a single green/red pair that denotes a change. Here are improvements to make:
-
-1. Show deletion (-) diffs. Right now we're only showing insertion (+) diffs. Diffs currently work by highlighting all of the new code in green with a simple text decoration. Instead, we would like to use code from VS Code's native diffEditor to show the diffs ("inline" mode). We could alternatively keep what we have and add red zones of the deleted code to indicate a deletion diff (-).
-
-2. Fix bugginess when the user presses "Accept" or "Reject" on a diff. One issue is that when a diff is accepted/rejected all of the diffs below should be updated (because they are now on different line numbers). There are other miscellaneous issues too.
-
-3. Make diff highlighting dynamic. Right now when the user edits text, all of the diffs and their highlights are cleared. Instead, we should update the highlighting of the diff. Each diff lives on a range of lines, and all changes inside that range or intersecting with it should update its highlighting.
-
-## ⭐⭐⭐ Build Cursor-style quick edits (ctrl+k).
-
-When the user presses ctrl+k, an input box should appear inline with the code that they were selecting. This is somewhat difficult to do because an extension alone cannot do this, and it requires creating a new component in the IDE. We think you can modify vscode's built-in "codelens" or "zone widget" components, but we are open to alternatives.
+Here are the most important topics on our Roadmap. More ⭐'s = more important. Please refer to our [Issues](https://github.com/voideditor/void/issues) page for the latest issues.
 
 ## ⭐⭐⭐ Make History work well.
 
 When the user submits a response or presses the apply/accept/reject button, we should add these events to the history, allowing the user to undo/redo them. Right now there is unexpected behavior if the user tries to undo or redo their changes.
 
-## ⭐⭐⭐ Improve Ctrl+L backend.
+## ⭐⭐⭐ Build Cursor-style quick edits (Ctrl+K).
 
-Right now, the model outputs entire files. Instead, we should change the prompt so that the model outputs partial changes like `// ... rest of file`. When the user clicks the "Apply" button, the model should rewrite the file and apply the partial changes in the correct locations.
-
-## ⭐⭐ Integrate with Ollama.
-
-We have an Ollama integration coded up in the extension, but it breaks. This is because Ollama has Node.js dependencies like 'path' and 'os' which cannot run in extensions (extensions have to be able to run in the browser). To fix this, we need to migrate Void's extension so that it runs natively into the VS Code editor so that we can access Node.js.

This is somewhat difficult to do because an extension alone cannot do this, and it requires creating a new component in the IDE. We think you can modify vscode's built-in "codelens" or "zone widget" components, but we are open to alternatives.
 
 ## ⭐⭐⭐ Creative.
 
-Feel free to build AI features beyond the standard Cursor ones. For example, creating better code search, or supporting AI agents that can edit across files and make multiple LLM calls.
+Examples: creating better code search, or supporting AI agents that can edit across files and make multiple LLM calls.
 
 Eventually, we want to build a convenient API for creating AI tools. The API will provide methods for creating the UI (showing an autocomplete suggestion, or creating a new diff), detecting event changes (like `onKeystroke` or `onFileOpen`), and modifying the user's file-system (storing indexes associated with each file), making it much easier to make your own AI plugin. We plan on building these features further along in timeline, but we wanted to list them for completeness.
 
 ## ⭐ One-stars.
 
-⭐ When user presses ctrl+L it should clear the sidebar's state.
-
-⭐ Let the user accept / reject all Diffs in an entire file via the sidebar.
-
-⭐ Allow the user to make multiple selections of code or files at once.
-
-⭐ Allow user to X out of their current selection.
+⭐ Let the user Accept / Reject all Diffs in an entire file via the sidebar.
 
 # Guidelines
 
-Please don't make big refactors without speaking with us first. We'd like to keep the codebase similar to vscode so we can periodically rebase, and if we have big changes that gets complicated.
+We're always glad to talk about new ideas, help you get set up, and make sure your changes align with our vision for the project. Feel free to shoot us a message in the #general channel of the [Discord](https://discord.gg/RSNjgaugJs) for any reason. Please check in especially if you want to make a lot of changes or build a large new feature.
 
-# Submitting a Pull Request
 
-Please submit a pull request once you've made a change. Here are a few guidelines:
 
-- A PR should be about one *single* feature change. The fewer items you change, the more likely the PR is to be accepted.
+## Submitting a Pull Request
 
-- Your PR should contain a description that first explains at a high level what you did, and then describes the exact changes you made (and to which files). Please don't use vague statements like "refactored code" or "improved types" (instead, describe what code you refactored, or what types you changed). 
+Please submit a pull request once you've made a change. You don't need to submit an issue.
 
-- Your title should clearly describe the change you made.
-
-- Add tags to help us stay organized!
-
-- Please don't open a new Issue for your PR. Just submit the PR.
-
-- Avoid refactoring and making feature changes in the same PR. 
-
-- Write good code. For example, a common mistake when people edit Void's config is to hard-code a default value like `'claude-3.5'` in 2+ separate places. Please follow best practices or describe your thought process if you had to compromise.
+Please don't use AI to write your PR 🙂.

+Here's an overview on how the extension works:
+
+- The extension mounts in `extension.ts`.
+
+- The Sidebar's HTML (everything in `sidebar/`) is built in React, and it's rendered by mounting a `<script>` tag - see `SidebarWebviewProvider.ts`.
+
+- Communication between the sidebar script and the extension takes place via API. You can search for "postMessage" to see where API calls happen.
