# R2R Local System Installation

This guide will walk you through installing and running R2R on your local system without using Docker. This method allows for more customization and control over individual components.

## Prerequisites

Before starting, ensure you have the following installed and/or available in the cloud:

* Python 3.10 or higher
* pip (Python package manager)
* Git
* Postgres + pgvector

## Install the R2R CLI and extra dependencies

First, install the R2R CLI with the additional `light` dependencies:

```bash
pip install 'r2r[core,ingestion-bundle]'
```

The `core` and `ingestion-bundle` dependencies, combined with a Postgres database, provide the necessary components to deploy a user-facing R2R application into production.

If you need advanced features like orchestration or parsing with `Unstructured.io` then refer to the <a href="/documentation/installation/full/docker"> full installation </a>.

## Environment Setup

R2R requires connections to various services. Set up the following environment variables based on your needs:

<AccordionGroup>
  <Accordion title="Cloud LLM Providers" icon="language">
    Note, cloud providers are optional as R2R can be run entirely locally.

    ```bash
     # Set cloud LLM settings
     export OPENAI_API_KEY=sk-...
     # export ANTHROPIC_API_KEY=...
     # ...
    ```
  </Accordion>

  <Accordion title="Postgres+pgvector" icon="database">
    With R2R you can connect to your own instance of Postgres+pgvector or a remote cloud instance.

    ```bash
     # Set Postgres+pgvector settings
     export POSTGRES_USER=$YOUR_POSTGRES_USER
     export POSTGRES_PASSWORD=$YOUR_POSTGRES_PASSWORD
     export POSTGRES_HOST=$YOUR_POSTGRES_HOST
     export POSTGRES_PORT=$YOUR_POSTGRES_PORT
     export POSTGRES_DBNAME=$YOUR_POSTGRES_DBNAME
     export R2R_PROJECT_NAME=$YOUR_PROJECT_NAME # see note below
    ```

    <Note>
      The `R2R_PROJECT_NAME` environment variable defines the tables within your Postgres database where the selected R2R project resides. If the required tables for R2R do not exist then they will be created by R2R during initialization.
    </Note>

    If you are unfamiliar with Postgres then <a href="https://supabase.com/docs"> Supabase's free cloud offering </a> is a good place to start.

## Running R2R

After setting up your environment, you can start R2R using the following command:

```bash
r2r serve
```

For local LLM usage:

```bash
r2r serve --config-name=local_llm
```

## Python Development Mode

For those looking to develop R2R locally:

1. Install Poetry: Follow instructions on the [official Poetry website](https://python-poetry.org/docs/#installation).

2. Clone and install dependencies:
   ```bash
   git clone git@github.com:SciPhi-AI/R2R.git
   cd R2R/py
   poetry install -E "core ingestion-bundle"
   ```

3. Setup environment:
   Follow the steps listed in the Environment Setup section above. Additionally, you may introduce a local .env file to make development easier, and you can customize your local `r2r.toml` to suit your specific needs.

4. Start your server:

```bash
poetry run r2r serve
```

## Next Steps

After successfully installing R2R:

1. **Verify Installation**: Ensure all components are running correctly by accessing the R2R API at [http://localhost:7272/v2/health](http://localhost:7272/v2/health).

2. **Quick Start**: Follow our [R2R Quickstart Guide](/documentation/quickstart) to set up your first RAG application.

3. **In-Depth Tutorial**: For a more comprehensive understanding, work through our [R2R Walkthrough](/cookbooks/walkthrough).

4. **Customize Your Setup**: Configure R2R components with the [Configuration Guide](/documentation/configuration).
