- mkdocs.yml with dark slate theme, nav for 12 ITPP projects
- build-docs.sh aggregates docs from all project repos
- .gitea/workflows/docs-publish.yml for nightly rebuild+deploy
- README and CHANGELOG for the itpp-docs repo itself
- docs-source/ populated from all 12 repos
- site/ ready for deployment to docs.itpropartner.com

-Aggregated MkDocs documentation site for all IT Pro Partner projects

+
+Aggregated MkDocs documentation site for all IT Pro Partner projects. Pulls READMEs, CHANGELOGs, and `docs/` directories from every project repo and builds a unified Material-for-MkDocs site served at [docs.itpropartner.com](https://docs.itpropartner.com/).
+
+## How It Works
+
+1. `build-docs.sh` clones/fetches every project repo listed in `REPOS`
+2. Copies each repo's `docs/`, `README.md`, and `CHANGELOG.md` into `docs-source/<project>/`
+3. `mkdocs build` renders the entire site to `site/`
+4. Gitea Actions (nightly) or manual rsync deploys to app3
+
+## Tech Stack
+
+- **Site generator:** MkDocs + Material for MkDocs theme
+- **CI/CD:** Gitea Actions (`.gitea/workflows/docs-publish.yml`)
+- **Hosting:** Nginx on app3 (152.53.241.111)
+
+## Quick Start
+
+```bash
+git clone https://git.itpropartner.com/ippadmin/itpp-docs.git
+cd itpp-docs
+pip install mkdocs mkdocs-material
+bash build-docs.sh
+mkdocs serve
+```
+
+## Deploy
+
+```bash
+# Manual deploy
+bash build-docs.sh && mkdocs build && rsync -avz site/ root@152.53.241.111:/home/ippadmin/htdocs/docs.itpropartner.com/
+
+# Or push to main — Gitea Actions handles rebuild + deploy nightly
+```
