Windows may show a reputation warning while the alpha installer is unsigned. Continue only if you downloaded it from the official repository.

The installer adds Hydron to your Start menu, can create a desktop shortcut, and adds the hydron command to your user PATH.
Launch Hydron
The app, CLI, .NET runtime, and local inference engine are installed together.
First run
Set up your workspace
1. Pick a folder

2. Install a small model
Open Launch, choose Available Models, and start with a compact model that fits your memory.
3. Connect agents
Install and sign in to Codex, Claude Code, or another supported agent separately. Hydron detects them automatically.
4. Start working
Chat with a model, open your folder in the IDE, or launch an agent for a project task.
Quick start
Common workflows
Chat with a model
Select a downloaded model, create a new chat, type your prompt, and press Enter. Shift+Enter adds a new line.
Launch an agent
Open Launch, choose an installed agent, select a workspace when asked, and use that provider's authenticated session.
Use the IDE
Open IDE, choose a folder, select a file, edit it, then use Run or Build when the required toolchain is installed.

FAQ
Troubleshooting
Why does Windows warn me about the installer?
The current alpha is not yet signed with a trusted Windows certificate. Download only from the official Hydron repository and verify the release checksum when provided.
Why is a model slow or unable to load?
The model may be too large for the available memory, or your CPU/GPU may not support it efficiently. Close memory-heavy apps and try a smaller model.
Why is an agent marked Not installed?
Hydron does not bundle third-party agents. Install the agent's official CLI, sign in, restart Hydron, and press Refresh.
Why will my project not run?
Hydron calls the language tools installed on your PC. Install the required compiler or interpreter, then reopen Hydron.
Can I use Hydron offline?
Downloaded local models can run offline. New downloads, cloud agents, and optional web research require internet access.
