 TypeScript errors become messier as the complexity of types increases. At some point, TypeScript will throw on you a shitty heap of parentheses and `"..."`.  
 This extension will help you understand what's going on. For example, in this relatively simple error:
 
-<img src="./assets/this.png" width="340.438px" />&nbsp; &nbsp; <img src="./assets/instead-of-that.png" width="350px" />

 ## Features
+
 - Syntax highlighting with your theme colors for types in error messages, supporting both light and dark themes
 - A button that leads you to the relevant type declaration next to the type in the error message
 - A button that navigates you to the error at [typescript.tv](http://typescript.tv), where you can find a detailed explanation, sometimes with a video
 - A button that navigates you to [ts-error-translator](https://ts-error-translator.vercel.app/), where you can read the error in plain English
 
 ## Supports
+
 - Node and Deno TypeScript error reporters (in `.ts` files)
 - JSDoc type errors (in `.js` and `.jsx` files)
 - React, Solid and Qwik errors (in `.tsx` and `.mdx` files)
 - Astro, Svelte and Vue files when TypeScript is enabled (in `.astro`, `.svelte` and `.vue` files)
 - Ember and Glimmer TypeScript errors and template issues reported by Glint (in `.hbs`, `.gjs`, and `.gts` files)

 ## Installation

+#### How to hide the original errors and make the types copyable
+
+Follow the instructions [there](./docs/hide-original-errors.md). unfortunately, this hack is required because of VSCode limitations.
+
 ## Why isn't it trivial
+
 1. TypeScript errors contain types that are not valid in TypeScript.  
-Yes, these types include things like `... more ...`, `{ ... }`, etc in an inconsistent manner. Some are also cutting in the middle because they're too long.
+   Yes, these types include things like `... more ...`, `{ ... }`, etc in an inconsistent manner. Some are also cutting in the middle because they're too long.
 2. Types can't be syntax highlighted in code blocks because the part of `type X = ...` is missing, so I needed to create a new TextMate grammar, a superset of TypeScript grammar called `type`.
 3. VSCode markdown blocks all styling options, so I had to find hacks to style the error messages. e.g., there isn't an inlined code block on VSCode markdown, so I used a code block inside a codicon icon, which is the only thing that can be inlined. That's why it can't be copied. but it isn't a problem because you can still hover on the error and copy things from the original error pane.

+To hide the original errors, display only the prettified ones, and make type blocks copyable, you can use the following hack:
+
+## The Hack
+
+1. Install the [Custom CSS and JS Loader](https://marketplace.visualstudio.com/items?itemName=be5invis.vscode-custom-css) extension from the VSCode marketplace.
+
+2. Follow the installation instructions provided by the extension, and use [this CSS file](./pretty-ts-errors-hack.css).
+
+## Why Do We Need This Hack?
+
+### Hiding Original Errors
+
+Unfortunately, VSCode doesn't currently support formatted diagnostics. Once it does, we'll be able to convert the extension to a TypeScript LSP Plugin that replaces the original error with the prettified version.  
+For updates on this feature, follow [this issue](https://github.com/yoavbls/pretty-ts-errors/issues/3).
+
+### Making Type Blocks Copyable
+
+VSCode sanitizes and removes most CSS properties for security reasons. We've opened an [issue](https://github.com/microsoft/vscode/issues/180496) and submitted a [PR](https://github.com/microsoft/vscode/pull/180498) to allow the use of the `display` property. This would enable us to layout the types in a way that allows copying.
+
+Until this change is approved, you can use the hack described above as a workaround.
