# Harness Open Source Self-Hosted Git and CI/CD Development Platform

Harness Open Source (formerly Gitness) is an end-to-end developer platform that integrates Git repository hosting, CI/CD pipelines, hosted development environments, and artifact registries in a single self-hosted binary.

## Installation

Use the upstream install or setup path that matches your environment:
- docker run -d \
- If your version is different than v3.21.11, run brew unlink protobuf
- $ make dep

Requirements and caveats from upstream:
- The latest publicly released docker image can be found on [harness/harness](https://hub.docker.com/r/harness/harness).

Basic usage or getting-started notes:
- To install Harness yourself, simply run the command below. Once the container is up, you can visit http://localhost:3000 in your browser.
- Check if you've already installed protobuf protoc --version
