+# Guide to Setting up JupyterHub Infrastructure
+
+JupyterHub is a powerful multi-user platform that allows you to provide a collaborative environment for data science and code execution. In your school's JupyterHub deployment, you can accommodate a large number of active users while ensuring each user gets their personal space. This guide will walk you through the key components and configurations of your JupyterHub infrastructure.
+
+## Overview
+
+### User Base
+
+- Your JupyterHub serves **10,000 to 11,000 active users**, making it a high-capacity platform for data science and coding.
+
+### Personal Spaces
+
+- JupyterHub ensures that **each user gets their personal space** where they can work independently.
+
+### Code Execution
+
+- JupyterHub provides an **authenticated way to perform multi-user arbitrary code execution**. You may currently use bcourses for this purpose.
+
+### Web-Based Code Execution
+
+- Users can execute code via web interfaces, which means **code execution doesn't rely on local memory**.
+
+## Infrastructure
+
+### Kubernetes Cluster
+
+- JupyterHub runs on a **Kubernetes (K8) cluster**, ensuring scalability and resource management.
+
+### Resource Allocation
+
+- The Kubernetes cluster manages CPU and memory allocation, allowing for efficient resource usage.
+
+### Autoscaling
+
+- Utilize **Calendar Autoscale** to automatically adjust resources based on demand.
+
+### Docker Images
+
+- Docker images are used to package software and its dependencies. In your setup, **Docker images capture the environment** for JupyterHub.
+
+### Supported Languages
+
+- JupyterHub supports a variety of programming languages, including:
+  - **Python**: Runs on Conda with the Conda ecosystem and Mamba package manager. It also supports PyPI packages.
+  - **R**: Supports RStudio and RSPM for package management.
+  - **Julia**: Provides support for Julia programming.
+
+### NbGitPuller
+
+- **NbGitPuller** is integrated, which allows users to easily access JupyterHub and pull repositories from GitHub, even if they are not familiar with Git.
+
+## Administration
+
+### API and Access Control
+
+- JupyterHub offers an **API** for administrative tasks and **private access control** to manage user permissions.
+
+## Network Layout
+
+Your JupyterHub infrastructure is organized as follows:
+
+1. **User** - Individual users who access JupyterHub.
+2. **CHP (Configurable HTTP Proxy)** - The CHP directs individual users to their respective personal spaces.
+3. **Hub** - Inside the hub, key components include:
+   - **Authenticator**: Verifies user credentials and authentication.
+   - **Spawner** - Manages user sessions, including the use of **KubeSpawner** for user environments.
+   - **Proxy** - Handles routing and load balancing of user requests.
+   - **SQLite Database** - Stores necessary information for user sessions.
