# Initialize a repository

Using *Setup* on the Repositories view in [Tessl Registry](https://tessl.io/registry) creates a `tessl.json` file and adds any tiles Tessl has for the dependencies your repository uses. It also creates a `.mcp.json` file so people working in the repository can use Tessl as an MCP server for their coding agent.

## Setup Tessl

* Select your workspace from the selector, with your name, on the top right of your screen.\

### The Pull request created

Pull requests may contain updates to `tessl.json` and `.mcp.json` based on your selections and the dependencies the repository contains.

* You or your pipeline automation would merge the request(s).\

## Troubleshooting

If you do not see your repositories listed, see [Connect Tessl to GitHub](/distribute/rollout-to-your-repositories/connect-tessl-to-github.md) or [Connect Tessl to GitLab](/distribute/rollout-to-your-repositories/connect-tessl-to-gitlab.md).

* It's possible you are only allowing specific repositories, in which case you may need to select the additional repositories you wish to display in the GitHub settings or provide a group token with access in GitLab.
