    "The `Gitlab` toolkit contains tools that enable an LLM agent to interact with a gitlab repository. \n",
    "The tool is a wrapper for the [python-gitlab](https://github.com/python-gitlab/python-gitlab) library. \n",
    "\n",
    "## Quickstart\n",
    "1. Install the python-gitlab library\n",
    "2. Create a Gitlab personal access token\n",
    "3. Set your environmental variables\n",
    "4. Pass the tools to your agent with `toolkit.get_tools()`\n",
    "\n",
    "Each of these steps will be explained in great detail below.\n",
    "\n",
    "1. **Get Issues**- fetches issues from the repository.\n",
    "\n",
    "2. **Get Issue**- fetches details about a specific issue.\n",
    "\n",
    "3. **Comment on Issue**- posts a comment on a specific issue.\n",
    "\n",
    "4. **Create Pull Request**- creates a pull request from the bot's working branch to the base branch.\n",
    "\n",
    "5. **Create File**- creates a new file in the repository.\n",
    "\n",
    "6. **Read File**- reads a file from the repository.\n",
    "\n",
    "7. **Update File**- updates a file in the repository.\n",
    "\n",
    "8. **Delete File**- deletes a file from the repository.\n",

    "* **GITLAB_BRANCH**- The branch where the bot will make its commits. Defaults to 'main.'\n",
    "* **GITLAB_BASE_BRANCH**- The base branch of your repo, usually either 'main' or 'master.' This is where pull requests will base from. Defaults to 'main.'\n"
