+# Git Hooks
+
+This directory contains Git hooks for the CV project.
+
+## Installation
+
+To install the hooks, run:
+
+```bash
+.githooks/install-hooks.sh
+```
+
+Or, configure Git to use this directory for hooks (Git 2.9+):
+
+```bash
+git config core.hooksPath .githooks
+```
+
+## Available Hooks
+
+### pre-commit
+
+Automatically compiles LaTeX files and generates WebP preview image.
+
+**Requirements:**
+- `pdflatex` (from TeX Live or similar LaTeX distribution)
+- `pdftoppm` (from poppler-utils)
+- `magick` (ImageMagick)
+
+The hook will:
+1. Compile `cv.tex` and `cv_de.tex` to PDF if they've been modified or staged
+2. Convert the first page of `cv.pdf` to a WebP image
+3. Save it as `img/cv.webp`
+4. Add the generated image to the commit
+
+### post-push
+
+Automatically syncs compiled PDFs to bocken.org after pushing.
+
+**Requirements:**
+- `rsync`
+- SSH access to `root@bocken.org`
+
+The hook will:
+1. Upload `cv.pdf` to `root@bocken.org:/var/www/static/`
+2. Upload `cv_de.pdf` to `root@bocken.org:/var/www/static/` (if exists)
