+GeoGebra Offline Instructions
+=============================
+
+Files created:
+- geogebra-offline.html  : Your original export modified to load a LOCAL deployggb.js
+- geogebra-embed.html    : A tiny wrapper that iframes geogebra-offline.html (handy for Jupyter or LMSes)
+- README_offline_geogebra.txt : This file
+
+What you still need:
+--------------------
+1) Download GeoGebra's loader script *once* and place it next to these HTML files as `deployggb.js`.
+
+   Example commands (run in the same folder as the HTML files):
+     curl -L -o deployggb.js https://www.geogebra.org/apps/deployggb.js
+   or
+     wget -O deployggb.js https://www.geogebra.org/apps/deployggb.js
+
+2) (Optional but recommended for FULLY offline use):
+   The loader (deployggb.js) normally fetches additional runtime assets from geogebra.org.
+   For truly offline usage (no internet at all), you must also mirror/host the GeoGebra Web app
+   files it requests (the "apps" runtime) and change the internal base URL used by the loader.
+   The exact files and paths can change by version; a common approach is to:
+   - Inspect the network requests in your browser dev tools when the app loads online.
+   - Mirror those directories (often under something like /apps/ or /html5/).
+   - Serve them locally (same directory or a local web server) and adjust paths in the loader
+     or via a local web server rewrite to point to your mirrored copies.
+
+   If 'deployggb.js' provides a configuration option for a base path, set it to your local copy.
+   Otherwise, you can host the mirrored assets on a local web server and keep the paths consistent.
+
+How to view locally:
+--------------------
+- Double-click geogebra-embed.html (or open in a browser). Some browsers restrict file:// + JS;
+  using a local web server avoids this. For example:
+
+    python3 -m http.server 8000
+
+  Then open: http://localhost:8000/geogebra-embed.html
+
+Using inside Jupyter:
+---------------------
+Place the HTML files in the notebook's working directory (or a subfolder) and in a cell run:
+
+    from IPython.display import IFrame
+    IFrame("geogebra-embed.html", width=920, height=660)
+
+Or inline the applet HTML directly (the contents of geogebra-offline.html) with:
+
+    from IPython.display import HTML
+    HTML(open("geogebra-offline.html", "r", encoding="utf-8").read())
+
+Notes:
+------
+- If your Jupyter notebook is not "trusted", JavaScript may be blocked. Use "Trust Notebook".
+- PDF export of notebooks won't preserve interactivity. Use HTML for sharing interactive content.
+- If you restructure paths, keep the iframe 'src' updated accordingly.
