Install in your project¶

Install N45 in any project where you want to use it.

Prerequisites¶

Node.js 22 or newer — needed to run npx n45-ai
Git installed on your machine
N45.AI account with an active license and logged in (npx n45-ai login)
One of the supported tools: Claude Code or Cursor
A project initialized as a git repository (run git init first if needed)

Run the command¶

From the root of your project:

cd /path/to/your/project
npx n45-ai install

The CLI detects your IDE automatically and installs accordingly.

What gets created¶

your-project/
├── .n45/
│   ├── bin/
│   └── (configuration files)
├── CLAUDE.md          # if Claude Code is installed
└── .cursor/           # if Cursor is installed

Item	Purpose
`.n45/bin/`	N45 binary used by the slash commands
`.n45/` config	Settings for this project (organization, license, language)
`CLAUDE.md`	Instruction block Claude Code reads on every session
`.cursor/rules/`	Equivalent for Cursor

What if I already have a CLAUDE.md?

N45 injects its block between  and  markers. Your existing content is preserved.

Verify the install¶

Open your IDE and type / in the chat. You should see four new slash commands:

/n45
/n45-feat
/n45-fix
/n45-status

If they appear, you're ready. See Your first /n45.

Update¶

To upgrade N45 in a project that already has it installed:

npx n45-ai update

This re-syncs the binary and the IDE configuration files to the latest version.
