+# Install the API7 Gateway (API7 Enterprise Edition) AI agent skills into your
+# AI coding agent.
+#
+# Each skill is a SKILL.md knowledge pack that teaches an agent (Claude Code,
+# Cursor, Copilot, Windsurf, OpenCode, ...) how to configure a live API7
+# Enterprise Edition gateway through the a7 CLI. This script copies them into
+# your agent's skills directory.
+#
+# Quick start (installs into ~/.claude/skills for Claude Code):
+#   curl -fsSL https://raw.githubusercontent.com/api7/a7/master/install.sh | sh
+#
+# Install somewhere else (e.g. a project-local Cursor rules dir):
+#   curl -fsSL https://raw.githubusercontent.com/api7/a7/master/install.sh | sh -s -- --dir ./.cursor/rules
+#   SKILLS_DIR=~/.config/opencode/skills sh -c "$(curl -fsSL https://raw.githubusercontent.com/api7/a7/master/install.sh)"
