 ## Contents
 
 - `devcontainer.json`: The primary configuration file defining the development environment.
-- `bootstrap.sh`: A script that runs after the container is created to initialize the environment (installing dependencies, setting up tools).
+- `bootstrap.sh`: Post-create script that initializes the environment (installing dependencies, setting up tools).
 
-## Features
+## Python Version
 
-- **Python Environment**: Pre-configured with Python 3.12.
-- **Tools**: Includes `uv` for fast package management and `make` for project tasks.
-- **Extensions**: Recommended VS Code extensions for Python development, including Ruff and Marimo.
+The Python version is controlled by the `.python-version` file in the repository root (single source of truth).
+
+**How it works:**
+1. The devcontainer uses a base Python image (3.12)
+2. `bootstrap.sh` reads `.python-version` and exports `PYTHON_VERSION`
+3. `make install` uses UV to create a venv with the exact Python version specified
+4. UV automatically downloads the correct Python version if needed
+
+No manual setup required - UV handles Python version management!
+
+## What's Configured
+
+The `.devcontainer` setup provides:
+
+- 🐍 **Python** runtime environment
+- 🔧 **UV Package Manager** - Fast Python package installer and resolver
+- ⚡ **Makefile** - For running project workflows
+- 🧪 **Pre-commit Hooks** - Automated code quality checks
+- 📊 **Marimo Integration** - Interactive notebook support with VS Code extension
+- 🔍 **Python Development Tools** - Pylance, Python extension, and optimized settings
+- 🚀 **Port Forwarding** - Port 8080 for development servers
+- 🔐 **SSH Agent Forwarding** - Full Git functionality with your host SSH keys
+
+## Usage
+
+### In VS Code
+
+1. Install the "Dev Containers" extension
+2. Open the repository in VS Code
+3. Click "Reopen in Container" when prompted
+4. The environment will automatically set up with all dependencies
+
+### In GitHub Codespaces
+
+1. Navigate to the repository on GitHub
+2. Click the green "Code" button
+3. Select "Codespaces" tab
+4. Click "Create codespace on main" (or your branch)
+5. Your development environment will be ready in minutes
+
+The dev container automatically runs the initialization script that:
+
+- Installs UV package manager
+- Configures the Python virtual environment
+- Installs project dependencies
+- Sets up pre-commit hooks
+
+## Publishing Devcontainer Images
+
+The repository includes workflows for building and publishing devcontainer images:
+
+### CI Validation
+
+The **DEVCONTAINER** workflow automatically validates that your devcontainer builds successfully:
+- Triggers on changes to `.devcontainer/**` files or the workflow itself
+- Builds the image without publishing (`push: never`)
+- Works on pushes to any branch and pull requests
+- Gracefully skips if no `.devcontainer/devcontainer.json` exists
+
+## VS Code Dev Container SSH Agent Forwarding
+
+Dev containers launched locally via VS code
+are configured with SSH agent forwarding
+to enable seamless Git operations:
+
+- **Mounts your SSH directory** - Your `~/.ssh` folder is mounted into the container
+- **Forwards SSH agent** - Your host's SSH agent is available inside the container
+- **Enables Git operations** - Push, pull, and clone using your existing SSH keys
+- **Works transparently** - No additional setup required in VS Code dev containers
+
+## Troubleshooting
+
+Common issues and solutions when using this configuration template.
+
+---
+
+### SSH authentication fails on macOS when using devcontainer
+
+**Symptom**: When building or using the devcontainer on macOS, Git operations (pull, push, clone) fail with SSH authentication errors, even though your SSH keys work fine on the host.
+
+**Cause**: macOS SSH config often includes `UseKeychain yes`, which is a macOS-specific directive. When the devcontainer mounts your `~/.ssh` directory, other platforms (Linux containers) don't recognize this directive and fail to parse the SSH config.
+
+**Solution**: Add `IgnoreUnknown UseKeychain` to the top of your `~/.ssh/config` file on your Mac:
+
+```ssh-config
+# At the top of ~/.ssh/config
+IgnoreUnknown UseKeychain
+
+Host *
+  AddKeysToAgent yes
+  UseKeychain yes
+  IdentityFile ~/.ssh/id_rsa
+```
+
+This tells SSH clients on non-macOS platforms to ignore the `UseKeychain` directive instead of failing.
+
+**Reference**: [Stack Overflow solution](https://stackoverflow.com/questions/75613632/trying-to-ssh-to-my-server-from-the-terminal-ends-with-error-line-x-bad-configu/75616369#75616369)

 2. Generating API documentation from the source code.
 3. Combining them into a cohesive "book" structure.

+## Documentation Customization
+
+You can customize the look and feel of your documentation by providing your own templates.
+
+### API Documentation (pdoc)
+
+The `make docs` command checks for a directory at `book/pdoc-templates`. If found, it uses the templates within that directory to generate the API documentation.
+
+To customize the API docs:
+1. Create the directory: `mkdir -p book/pdoc-templates`
+2. Add your Jinja2 templates (e.g., `module.html.jinja2`) to this directory.
+
+See the [pdoc documentation](https://pdoc.dev/docs/pdoc.html#templates) for more details on templating.
+
+### Companion Book (minibook)
+
+The `make book` command checks for a template at `book/minibook-templates/custom.html.jinja2`. If found, it uses this template for the minibook generation.
+
+To customize the book:
+1. Create the directory: `mkdir -p book/minibook-templates`
+2. Create your custom template at `book/minibook-templates/custom.html.jinja2`.
