+
+You can install and update QodeAssist directly from within Qt Creator by adding the QodeAssist registry as an external extension repository.
+
+1. Open the Extensions page (`Qt Creator → Extensions`) and switch to the **Browser** tab
+2. Enable **Use External Repository**
+3. Next to **Repository URLs**, click **Add** and paste the registry archive URL matching your Qt Creator version:

+4. Click **Apply** — QodeAssist will appear in the extensions list, where you can **Install** it
+5. Updates can be installed from the same screen when a new version is published

+### Skills
+
+**Agent Skills** package specialized instructions and workflows into reusable folders the AI loads on demand. QodeAssist implements the open [Agent Skills](https://agentskills.io) format, so skills authored for Claude Code, Cursor, or other agents work as-is.
+
+A skill is a folder containing a `SKILL.md` file — YAML frontmatter (`name`, `description`) plus Markdown instructions:
+
+```
+my-skill/
+└── SKILL.md
+```
+
+```markdown
+---
+name: my-skill
+description: What the skill does and when to use it.
+---
+
+# My Skill
+
+Step-by-step instructions for the task...
+```
+
+**Where skills are discovered:**
+- **Project skills** — project-relative subdirectories (default `.qodeassist/skills/` and `.claude/skills/`), configured in `Projects → QodeAssist → Skills`. Project skills win over global ones on a name collision.
+- **Global skills** — absolute directories shared across all projects (default includes `~/.claude/skills/`), configured in `Tools → Options → QodeAssist → Skills`.
+
+Both settings pages show the list of currently discovered skills.
+
+**How skills are used in Chat:**
+- **Automatically** — each skill's name and description is added to the system prompt; when a request matches, the model loads the full instructions via the `load_skill` tool (requires a tool-calling model).
+- **Explicitly** — type `/` in the chat input and pick a skill from the popup; its instructions are injected into that one message. Works with any model.
+- **Always-on** — a skill whose frontmatter has `metadata: always-on: "true"` is injected into every chat request automatically.
+
+Enable or disable the whole feature in `Tools → Options → QodeAssist → Skills`.
+
 ### MCP Server
 
 QodeAssist can run an **MCP (Model Context Protocol) server** on `localhost`, exposing the tools above to external clients — so you can use QodeAssist's project awareness from Claude Code CLI, VS Code, Cursor, Claude Desktop, or any other MCP-capable client.
