+# AGENTS.md
+
+## Project Overview
+
+WSO2 Developer Platform (formerly Choreo) documentation site, built with **MkDocs** and the **Material for MkDocs** theme. The site uses a **dual-perspective documentation model**:
+
+- `en/developer-docs/` — Developer view (application developers)
+- `en/pe-docs/` — Platform Engineer view (platform operators/admins)
+
+Each perspective has its own `mkdocs.yml`, navigation structure, and output directory. Changes may need to go into one or both perspectives depending on scope.
+

+
+## Build & Development Commands
+
+### Setup
+
+```bash
+cd en/
+pip3 install -r requirements.txt
+npm install -g markdown-spellcheck@1.3.1
+npm install -g markdown-link-check@3.10.3
+```
+
+### Build and validate (spell-check + link-check + build)
+
+```bash
+cd en/
+./serve.sh
+```
+
+### Serve locally for iterative development
+
+```bash
+# From en/developer-docs/ or en/pe-docs/
+mkdocs serve                # Standard serve at localhost:8000
+mkdocs serve --dirtyreload  # Faster reload (requires strict: false in mkdocs.yml)
+```
+
+### Build only (no validation)
+
+```bash
+mkdocs build --config-file en/developer-docs/mkdocs.yml
+mkdocs build --config-file en/pe-docs/mkdocs.yml
+```
+
+## Architecture
+
+### Dual-Perspective Model
+
+Both perspectives share a custom theme (`en/theme/material/`) but have independent:
+- `mkdocs.yml` config files with separate `nav` sections and `site_dir` outputs
+- `docs/` directories with their own markdown content and assets
+- Redirect maps (developer-docs has 50+ redirects; pe-docs has minimal)
+
+The `mkdocs.yml` files contain `extra` metadata fields (`developer_docs_path`, `pe_docs_path`, `show_perspective_dropdown`) that drive the perspective selector UI.
+
+### Key Directories
+
+- `en/theme/material/` — Custom Material theme overrides (shared by both perspectives): base templates, home page template, custom CSS/JS
+- `en/dictionary/` — Custom spell-check dictionary (`en_US-large`)
+- `.github/workflows/ci.yml` — GitHub Actions: builds both doc sites, deploys to `gh-pages-v2` branch
+- `.azure/` — Azure DevOps pipelines: production (`main` branch) and dev (`dev` branch) deployments to Azure Storage + CDN
+
+### Content Structure Within Each Perspective
+
+Markdown files live under `docs/` in each perspective directory. Assets (images, CSS, JS) are duplicated per perspective under `docs/assets/`. Navigation order is defined in the `nav` section of each `mkdocs.yml`.
+
+### MkDocs Plugins in Use
+
+`search`, `include-markdown` (file inclusion/reuse), `glightbox` (image lightbox), `open-in-new-tab`, `markdownextradata`, `redirects`, `minify`
+
+### Markdown Extensions
+
+Admonitions, definition lists, footnotes, PyMdown Extensions (tabs, task lists, superfences, snippets), code highlighting via Pygments, attribute lists.
+
+## Contribution Workflow
+
+1. Work on the `PE` branch (this is the main branch)
+2. Determine if the change applies to developer-docs, pe-docs, or both
+3. Run `./serve.sh` from `en/` to validate spelling and links before submitting
+4. PR template has checkboxes for which perspective(s) are affected and tested
+5. Before PR: ensure `strict: true` in mkdocs.yml (set to `false` only during local drafting)
+
+## Important Conventions
+
+- Page structure changes must update the redirect maps in `mkdocs.yml` to preserve existing URLs
+- The `extra` section in `mkdocs.yml` defines product naming variables (`product_name`, `short_name`, `cli_root_name`) used across docs
+- Style/tone guidelines are in the GitHub wiki: "Choreo Documentation Guidelines and Best Practices"
