# Introduction - Qodo Merge (and open-source PR-Agent)

# Introduction

After installation, there are three basic ways to invoke Qodo Merge:

1. Locally running a CLI command
2. Online usage - by commenting on a PR
3. Enabling Qodo Merge tools to run automatically when a new PR is opened

Specifically, CLI commands can be issued by invoking a pre-built docker image, or by invoking a locally cloned repo.

For online usage, you will need to setup either a GitHub App or a GitHub Action (GitHub), a GitLab webhook (GitLab), or a BitBucket App (BitBucket). These platforms also enable to run Qodo Merge specific tools automatically when a new PR is opened, or on each push to a branch.
