+# autocompile.sh
+
+Auto-pulls, watches, and recompiles a `.tex` file with `pdflatex` on save (via `inotifywait`), opens the PDF in Evince, and auto-commits + pushes back to your git remote on exit (Ctrl+C).
+
+## Requirements
+`git`, `pdflatex`, `inotify-tools`, `evince`, `termux-x11`, `fluxbox`, `wmctrl` or `xdotool` (Termux/Android setup).
+
+## Usage
+```bash
+./autocompile.sh yourfile.tex
+```
+If the file doesn't exist, a minimal template is created for you.
+
+## Notes
+- Requires a configured git remote (`origin`) with push access.
+- Network operations (pull/push) time out gracefully after 10s if offline.
