## Getting Started
-### Human-Readable Documentation and Examples
+### Natural Language or Python
-The following human-readable documentation and examples are useful for new starters:
+You can use **PyAutoLens** by describing what you want in natural language, through the
+[**PyAutoLens AI Assistant**](https://github.com/PyAutoLabs/autolens_assistant), or by writing Python yourself. Both
+routes use the same software. To start in natural language, paste this prompt into Claude Code, Codex or another AI
+coding agent:

+I want to do strong lensing science with PyAutoLens (https://github.com/PyAutoLabs/PyAutoLens) and the

+cd into it and follow its AGENTS.md.

+Begin the "start here" guide for a new user.
+```
+
+The assistant takes you through the [Start Here](https://pyautolens.readthedocs.io/en/latest/overview/overview_1_start_here.html) page as a conversation (grids, light and mass profiles, ray-tracing, then simulating and fitting a strong lens), one step at a time, then
+helps you get started on your own lenses. Claude Code and Codex are recommended, and sustained scientific use
+normally needs paid access to one of them. Free options are listed on the
+[AI Options](https://github.com/PyAutoLabs/PyAutoScientist/blob/main/AI_OPTIONS.md) page.
+[Start Here](https://pyautolens.readthedocs.io/en/latest/overview/overview_1_start_here.html#natural-language-or-python) explains why **PyAutoLens** is designed to be used in natural
+language, and why its Python API is not going anywhere.
+
+### Documentation and Examples
+
+All of the documentation and examples are written for people to read:
- [The PyAutoLens readthedocs](https://pyautolens.readthedocs.io/en/latest): which includes [an overview of PyAutoLens's core features](https://pyautolens.readthedocs.io/en/latest/overview/overview_1_start_here.html), [a new user starting guide](https://pyautolens.readthedocs.io/en/latest/overview/overview_2_new_user_guide.html) and [an installation guide](https://pyautolens.readthedocs.io/en/latest/installation/overview.html).
- [The introduction Jupyter Notebook on Google Colab](https://colab.research.google.com/github/PyAutoLabs/autolens_workspace/blob/2026.10.29.1/start_here.ipynb): try **PyAutoLens** in a web browser (without installation).
- [The autolens_workspace GitHub repository](https://github.com/PyAutoLabs/autolens_workspace): example scripts covering every **PyAutoLens** use case.
- [The HowToLens GitHub repository](https://github.com/PyAutoLabs/HowToLens): a Jupyter notebook lecture series teaching strong lensing and lens modeling from the ground up.
-### PyAutoLens AI Assistant
-
-The [**PyAutoLens AI Assistant**](https://github.com/PyAutoLabs/autolens_assistant) lets you do gravitational lensing science in natural language from inside an AI coding agent. You can get started simply by asking it a question about gravitational lensing or describing the task you would like to perform with **PyAutoLens**. See the [autolens_assistant GitHub page](https://github.com/PyAutoLabs/autolens_assistant) for its full scope and instructions.
-
-**The assistant runs inside an AI coding agent: Claude Code or Codex are recommended. Sustained scientific use normally needs paid access to one of them (a personal subscription, institutional access or API billing). OpenCode is an experimental alternative whose client is free but whose model access, cost and capability depend on the provider. Browser chat routes (ChatGPT or Claude with a GitHub connector) are no longer supported.**

+
+**Why natural language?** Turning a scientific idea into an analysis has always meant expressing it through the syntax
+of a programming language. That syntax was never the science: it is the interface between your ideas and the
+computer. **PyAutoLens** is designed so you can describe a lensing analysis in the language you use to think and write
+about it, while you supply the understanding, direction and judgement. The
+[PyAuto AI Policy](https://github.com/PyAutoLabs/PyAutoScientist/blob/main/AI_POLICY.md) explains this approach in
+more detail.
+
+**Python is not going anywhere.** Every **PyAutoLens** feature remains available through its Python API, and the
+assistant writes ordinary **PyAutoLens** code that you can read, run and change. All the documentation is written for
+people to read. The rest of this page is the Python overview, the
+[autolens_workspace](https://github.com/PyAutoLabs/autolens_workspace) holds runnable examples for every use case, and
+the [HowToLens](https://github.com/PyAutoLabs/HowToLens) lectures teach strong lensing and lens modeling from first
+principles. That understanding is what lets you direct an analysis with expertise, whether you do it in natural
+language or in Python.
