-# Obsidian Sample Plugin
+# Better Math in Callouts/Blockquotes
 
-This is a modified version of https://github.com/obsidianmd/obsidian-sample-plugin.
+This is an [Obsidian.md](https://obsidian.md) plugin to add a better support for math rendering inside callouts/blockquotes to Live Preview.
 
-- `*.ts` files are put in the `src` directory
-- The plugin class definition and settings-related code are separated into `main.ts` and `settings.ts`
-- Release GitHub action is already there
-  - Don't forget to go to `Settings > Actions > General > Workflow permissions` and turn on `Read and write permissions`
+> Note: The features of this plugin are originally a part of [Math Booster](https://ryotaushio.github.io/obsidian-math-booster/), another community plugin of mine. Once this plugin is approved by the Obsidian team, they will be removed from Math Booster.
+
+## Features
+
+### Math in Callouts
+
+In Live Preview, the vanilla Obsidian does not render MathJax in callouts while editing them. 
+This plugin solves this problem.
+
+Moreover, it also enables proper handling of multi-line math blocks; see [the next section](math-in-lockquotes) below.
+
+This feature can be toggled in the plugin setting tab.
+
+#### Example
+
+ Without this plugin                 | With this plugin
+:-----------------------------------:|:----------------------------------:
+![Before](fig/callout-before.png) | ![After](fig/callout-after.png)
+
+### Math in Blockquotes
+
+In Live Preview, the vanilla Obsidian misunderstands a ">" symbol at the beginning of a line in a blockquote or a callout as an inequality sign ("greater than") in multi-line math blocks, while Reading View properly recognizes them. This plugin makes them consistent with Reading View. 
+
+This feature also can be toggled in the plugin setting tab.
+
+#### Example
+
+```
+> $$
+> \begin{align}
+> a &= b \\
+>   &= c
+> \end{align}
+> $$
+```
+
+ Without this plugin                 | With this plugin

+
+## Installation
+
+Since this plugin is still in beta, it's not on the community plugin browser yet.
+
+But you can install the latest beta release using [BRAT](https://github.com/TfTHacker/obsidian42-brat):
+
+1.  Install BRAT and enable it.
+2.  Go to `Options`. In the `Beta Plugin List` section, click on the `Add Beta plugin` button.
+3.  Copy and paste `RyotaUshio/obsidian-math-in-callout` in the pop-up prompt and click on **Add Plugin**.
+4.  _(Optional but highly recommended)_ Turn on `Auto-update plugins at startup` at the top of the page.
+5.  Go to `Community plugins > Installed plugins`. You will find “Better Math in Callouts/Blockquotes” in the list. Click on the toggle button to enable it.
