+# Slack Message Formatter
+
+This slash command formats messages for Slack with pixel-perfect accuracy. It converts standard Markdown to Slack-compatible output with two delivery paths:
+
+1. **Copy-paste** — Rich HTML that preserves formatting when pasted into Slack's compose box
+2. **API/Webhook** — Slack mrkdwn syntax for bots, automation, and CI/CD
+
+## Key Features
+
+- Converts bold, italic, strikethrough, code, links, headings, tables, task lists, and more
+- Handles Slack mentions (`<@U...>`, `<#C...>`, `<!here>`) as pass-through
+- Generates a Slack-themed browser preview page
+- Copies rich HTML to clipboard for instant paste into Slack
+- Supports direct webhook sending via `CCH_SLA_WEBHOOK` environment variable
+- Converts 150+ emoji shortcodes to native Unicode
+
+## Usage
+
+```
+/slack-message-formatter preview
+/slack-message-formatter send
+```
+
+Write your message in standard Markdown, and the formatter handles conversion to Slack's mrkdwn syntax and rich HTML automatically.
