+# Jira Skill for CodeMie / Claude Code
+
+Enables Claude Code to interact with Jira as a first-class citizen of the AI software
+development lifecycle. Claude can read tickets before implementing features, update ticket
+status, add comments, manage sprints, and more — all via the
+[`jira-cli`](https://github.com/ankitpokhrel/jira-cli) binary.
+
+---
+
+## Installation
+
+### macOS
+
+```bash
+brew install ankitpokhrel/jira-cli/jira-cli
+```
+
+### Linux
+
+Download the latest binary from [GitHub Releases](https://github.com/ankitpokhrel/jira-cli/releases):
+
+```bash
+# Example for Linux amd64
+curl -L https://github.com/ankitpokhrel/jira-cli/releases/latest/download/jira_linux_x86_64.tar.gz | tar xz
+chmod +x jira
+sudo mv jira /usr/local/bin/jira
+```
+
+Verify the installation:
+
+```bash
+jira version
+```
+
+---
+
+## Configuration (one-time per Jira instance)
+
+Run the interactive setup wizard:
+
+```bash
+jira init
+```
+
+The wizard will ask for:
+- **Installation type**: `Cloud` (Atlassian Cloud) or `Local` (Server / Data Center)
+- **Server URL**: e.g., `https://yourcompany.atlassian.net` or `https://jira.yourcompany.com`
+- **Login**: your email (Cloud) or username (on-premise)
+- **API token**: see the Credentials section below
+
+Config is saved to `$HOME/.config/.jira/.config.yml`. Do **not** commit this file to version control.
+
+---
+
+## Credentials
+
+### Atlassian Cloud
+
+1. Generate an API token at: https://id.atlassian.com/manage-profile/security/api-tokens
+2. Export it in your shell profile (`~/.zshrc` or `~/.bashrc`):
+
+```bash
+export JIRA_API_TOKEN="your-atlassian-api-token"
+```
+
+### On-premise (Server / Data Center) — Personal Access Token
+
+```bash
+export JIRA_API_TOKEN="your-personal-access-token"
+export JIRA_AUTH_TYPE="bearer"
+```
+
+Add all exports to your `~/.zshrc` or `~/.bashrc` for persistence.
+
+---
+
+## Verification
+
+After configuration, verify the connection:
+
+```bash
+jira me --plain
+```
+
+You should see your Jira user profile. If it fails, re-run `jira init` or check your token.
+
+---
+
+## Multi-project / Multi-instance Setup
+
+If you work with multiple Jira instances, use a per-project config file:
+
+```bash
+# Initialize a project-specific config
+jira init -c ./jira-project.yml
+
+# Use it for commands
+jira issue list -c ./jira-project.yml
+
+# Or set an env var
+export JIRA_CONFIG_FILE=./jira-project.yml
+```
+
+---
+

+## Optional: Install jq
+
+`jq` is not required but useful for processing `--raw` JSON output from jira-cli:
+
+```bash
+brew install jq   # macOS
+apt install jq    # Ubuntu/Debian
+```
