+# Syntax Highlighting powered by Torchlight
+
+This WordPress plugin provides a Gutenberg block that syntax highlights your code powered by [Torchlight](https://torchlight.dev/).
+
+## Installation
+
+Download this repository inside the `wp-content/plugins` folder, then access the folder and run the `composer install` command. This will install the required dependencies.
+
+Before use this plugin you need to create an API Key from Torchlight. If you don't have an account, [register here](https://app.torchlight.dev/register).
+
+After you obtain the API Token, copy and paste it in the plugin's settings page: `Settings > Syntax Highlighting`.
+
+## Usage
+
+In your Gutenberg editor, insert a code block and paste your code. In the sidebar you'll see the Syntax Highlighting options:
+
+### Gutenberg Options
+
+- Language. The code block programming language.
+- Theme. The code block theme.
+- Line numbers. Whether to show line numbers in the code block.
+- Line number starts at. Start the line numbers at a specific number.
+- Diff indicators. Whether to show the diff indicators in the code block.
+
+## Server Side Rendering
+
+The Gutenberg block won't use any JavaScript to syntax highlight your code. It will highlight your code using the [Torchlight API](https://torchlight.dev/) in the backend, and send the response to your frontend.
+
+## Cache
+
+When you syntax highlight your code for the first time, it will run a request to Torchlight API and the response will be stored in a WordPress transient.
+
+The transient key contains a `md5` hash value constructed from the code block attributes and the content (or code).
+
+A transient key looks like this:
+
+```text
+_transient_syntax_highlighting_55116e908cd06545a7e4bef7f1ce2d2f	
+```
+
+The transient expiration is one month, that means when it expires the code block needs to run the API request again.
+
+## Settings
+
+The plugin accepts 2 settings:
+
+- API Token. Your Torchlight API Token.
+- Theme. The default code theme. You can change the theme later for a specific block.
