## Overview

#### Purpose and Entry Points
This is a static Markdown knowledge repository for revising a Linux course, not an executable application. The top-level entry point is `README.md`, which directs readers into numbered topic directories. The introductory learning sequence begins in `01-getting-started/01-fundamentals.md` and proceeds through setup and package management.

#### Curriculum Structure
The numbered root directories establish the repository’s primary architecture: an ordered Linux-learning path. Numeric prefixes encode intended progression and keep sections discoverable without a generated site or navigation runtime:
- `01-getting-started/`
- `02-folder-structure/`
- `03-user-management/`
- `10-disk-management/`

#### Foundation and Environment Setup
The first module defines Linux concepts, filesystem basics, distributions, local setup, and package management. It forms the conceptual and environment boundary before operational administration topics:
- `01-getting-started/01-fundamentals.md`
- `01-getting-started/02-linux-structure.md`
- `01-getting-started/04-setup.md`
- `01-getting-started/05-package-manager.md`

#### Filesystem and Access Administration
Filesystem navigation, file operations, identity management, and authorization are separate learning domains but jointly describe host-level access control. Readers move from locating resources to managing users and enforcing permissions:
- `02-folder-structure/README.md`
- `03-user-management/README.md`
- `04-file-management/README.md`
- `06-file-permissions/README.md`

#### Interactive Operations and Process Control
Command-line editing and process management cover interactive administration: modifying system files with VI and inspecting or controlling running workloads:
- `05-vi-shortcuts/README.md`
- `07-process-management/README.md`

#### Observability, Networking, and Storage
The final operational areas focus on diagnosing system state, connectivity, and persistent capacity. These are distinct host-management boundaries, typically used together when troubleshooting Linux systems:
- `08-monitoring/README.md`
- `09-networking/README.md`
- `10-disk-management/README.md`

#### Runtime and External Dependencies
There is no application runtime, build pipeline, service integration, or infrastructure-as-code represented in the tree. Content is plain Markdown intended for a reader using a Linux environment; setup material explicitly addresses Linux on Windows and macOS in `01-getting-started/04-setup.md`. The course content is attributed to an external YouTube course by Abhishek Veeramalla, but the repository itself contains revision documentation rather than an API or service client.
