## What it is
Ledge is a DevOps knowledge and tooling platform distilled from ThoughtWorks' DevOps, agile, and lean practices. It is a static site built with Angular that presents best practices, case studies, patterns, implementation handbooks, metrics, and a DevOps tools periodic table.

## Use cases
- learn devops best practices
- choose devops tools with a periodic table
- plan a devops transformation for my company
- find devops implementation handbooks and playbooks
- measure devops transformation with KPIs
- study case studies of enterprises adopting devops
- browse devops patterns and principles

## When to choose
- you want curated DevOps knowledge, case studies, and handbooks in one place
- you need help selecting DevOps tooling across the delivery lifecycle
- you are planning or measuring a DevOps transformation in an enterprise

## When to avoid
- you need a hands-on DevOps toolchain rather than a knowledge reference
- you require actively developed features - the project is in maintenance mode
- you need English-first content - most material is in Chinese

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, developer-tools, static-site-generator, workflow-automation
- domain: developer-tools, documentation, education
- platform: cross-platform
- tags: devops-knowledge, docs-as-code, knowledge-management, agile, lean, devops-transformation, angular, tooling-periodic-table, devops, automation, web-server, nodejs
