Uses Jekyll to generate the documentation.

- Uses Jekyll to generate the documentation, which's source and configs
  live in the `/jekyll` folder.
- The documentation will still be built to the `/docs` folder and be
  ignored by git.
- Currently, the documentation is one big page (similar to rust-analyzer's).
- All the current feature demos and introduction are copied from the
  Code Navigation post on the Rails At Scale blog. We will gradually
  fill in the rest of the documentation.
- To avoid duplication, most of README's content has been moved to the
  documentation too.
- Because Jekyll server isn't able to link to assets outside of the source
  directory, we need to copy the Ruby LSP icon to `/jekyll` folder.

-## Features
+## Getting Started
 
-![Ruby LSP demo](vscode/extras/ruby_lsp_demo.gif)
-
-The Ruby LSP features include
-
-- Semantic highlighting
-- Symbol search and code outline
-- RuboCop errors and warnings (diagnostics)
-- Format on save (with RuboCop or Syntax Tree)
-- Format on type
-- Debugging support
-- Running and debugging tests through VS Code's UI
-- Go to definition for classes, modules, constants and required files
-- Showing documentation on hover for classes, modules and constants
-- Completion for classes, modules, constants and require paths
-- Fuzzy search classes, modules and constants anywhere in the project and its dependencies (workspace symbol)
-
-As of July 2024, Ruby LSP has received significant enhancements to its code navigation features. For an in-depth look at these improvements, including video demonstrations, check out this [article](https://railsatscale.com/2024-07-18-mastering-ruby-code-navigation-major-enhancements-in-ruby-lsp-2024/). Despite these advancements, we plan to continue enhancing its code navigation support even further. You can follow our progress on this [GitHub issue](https://github.com/Shopify/ruby-lsp/issues/899).
-
-See complete information about features [here](https://shopify.github.io/ruby-lsp/RubyLsp/Requests.html).
-
-If you experience issues, please see the [troubleshooting
-guide](https://github.com/Shopify/ruby-lsp/blob/main/TROUBLESHOOTING.md).
-
-## Usage
-
-### With VS Code
-
-If using VS Code, all you have to do is install the [Ruby LSP
-extension](https://marketplace.visualstudio.com/items?itemName=Shopify.ruby-lsp) to get the extra features in the
-editor. Do not install the `ruby-lsp` gem manually.
-
-For more information on using and configuring the extension, see [vscode/README.md](vscode/README.md).
-
-### With other editors
-
-See [editors](EDITORS.md) for community instructions on setting up the Ruby LSP, which current includes Emacs, Neovim, Sublime Text, and Zed.
-
-The gem can be installed by doing
-```shell
-gem install ruby-lsp
-```
-
-and the language server can be launched running `ruby-lsp` (without bundle exec in order to properly hook into your
-project's dependencies).
-
-### Documentation
-
-See the [documentation](https://shopify.github.io/ruby-lsp) for more in-depth details about the
-[supported features](https://shopify.github.io/ruby-lsp/RubyLsp/Requests.html).
-
-For creating rich themes for Ruby using the semantic highlighting information, see the [semantic highlighting
-documentation](SEMANTIC_HIGHLIGHTING.md).
-
-### Configuring code indexing
-
-By default, the Ruby LSP indexes all Ruby files defined in the current project and all of its dependencies, including
-default gems, except for
-
-- Gems that only appear under the `:development` group
-- All Ruby files under `test/**/*.rb`
-
-This behaviour can be overridden and tuned. Learn how to configure it [for VS Code](vscode/README.md#Indexing-Configuration) or [for other editors](EDITORS.md#Indexing-Configuration).
-
-Note that indexing-dependent behavior, such as definition, hover, completion or workspace symbol will be impacted by
-the configuration changes.
-
-The older approach of using a `.index.yml` file has been deprecated and will be removed in a future release.
-
-```yaml
-# Exclude files based on a given pattern. Often used to exclude test files or fixtures
-excluded_patterns:
-  - "**/spec/**/*.rb"
-
-# Include files based on a given pattern. Can be used to index Ruby files that use different extensions
-included_patterns:
-  - "**/bin/*"
-
-# Exclude gems by name. If a gem is never referenced in the project's code and is only used as a tool, excluding it will
-# speed up indexing and reduce the amount of results in features like definition or completion
-excluded_gems:
-  - rubocop
-  - pathname
-
-# Include gems by name. Normally used to include development gems that are excluded by default
-included_gems:
-  - prism
-```
-
-### Addons
-
-The Ruby LSP provides an addon system that allows other gems to enhance the base functionality with more editor
-features. This is the mechanism that powers addons like
-
-- [Ruby LSP Rails](https://github.com/Shopify/ruby-lsp-rails)
-- [Ruby LSP RSpec](https://github.com/st0012/ruby-lsp-rspec)
-- [Ruby LSP rubyfmt](https://github.com/jscharf/ruby-lsp-rubyfmt)
-
-Additionally, some tools may include a Ruby LSP addon directly, like
-
-- [Standard Ruby (from v1.39.1)](https://github.com/standardrb/standard/wiki/IDE:-vscode#using-ruby-lsp)
-
-Other community driven addons can be found in [rubygems](https://rubygems.org/search?query=name%3A+ruby-lsp) by
-searching for the `ruby-lsp` prefix.
-
-For instructions on how to create addons, see the [addons documentation](ADDONS.md).
