# Zed Docs

Welcome to Zed's documentation.

This is built on push to `main` and published automatically to [https://zed.dev/docs](https://zed.dev/docs).

To preview the docs locally you will need to install [mdBook](https://rust-lang.github.io/mdBook/), and then run:

```
mdbook serve docs
```

## Images and videos

To add images or videos to the docs, upload them to another location (e.g., zed.dev, GitHub's asset storage) and then link out to them from the docs.

Putting binary assets such as images in the Git repository will bloat the repository size over time.

## Internal notes:

- We have a Cloudflare router called `docs-proxy` that intercepts requests to `zed.dev/docs` and forwards them to the "docs" Cloudflare Pages project.
- CI uploads a new version to the Pages project from `.github/workflows/deploy_docs.yml` on every push to `main`.

### Table of Contents

The table of contents files (`theme/page-toc.js` and `theme/page-doc.css`) were initially generated by [`mdbook-pagetoc`](https://crates.io/crates/mdbook-pagetoc).

Since all these preprocessor does is generate the static assets, we don't need to keep it around once they have been generated.

### Highlight.js

mdBook by default uses Highlight.js with a custom theme for syntax highlighting with automatic language detection turned off for a list subset of common [supported languages](https://rust-lang.github.io/mdBook/format/theme/syntax-highlighting.html#supported-languages).

We've updated with a highlight.js that supports additional languages (`scheme`).
To regenerate highlight.js run the following:

```
git clone https://github.com/highlightjs/highlight.js
cd highlight.js
git checkout 10-stable
node tools/build.js :common scheme

ZED_FOLDER=~/code/zed
cp build/highlight.min.js $ZED_FOLDER/docs/theme/highlight.js
```

Be sure to edit the code block above to include the any added languages (after `scheme`).
