-libtmux is a typed Python API over [tmux], the terminal multiplexer. Stop shelling out and parsing `tmux ls`. Instead, interact with real Python objects: `Server`, `Session`, `Window`, and `Pane`. The same API powers [tmuxp], so it stays battle-tested in real-world workflows.
+## What is libtmux?
 
-### ✨ Features
+**libtmux** is a fully typed Python API that provides seamless control over [tmux](https://github.com/tmux/tmux), the popular terminal multiplexer. Design your terminal workflows in clean, Pythonic code with an intuitive object-oriented interface.
 
-- Typed, object-oriented control of tmux state
-- Query and [traverse](https://libtmux.git-pull.com/topics/traversal/) live sessions, windows, and panes
-- Raw escape hatch via `.cmd(...)` on any object
-- Works with multiple tmux sockets and servers
-- [Context managers](https://libtmux.git-pull.com/topics/context_managers/) for automatic cleanup
-- [pytest plugin](https://libtmux.git-pull.com/api/pytest-plugin/) for isolated tmux fixtures
-- Proven in production via tmuxp and other tooling
+## Why Use libtmux?
 
-## Requirements & support
+- 💪 **Powerful Abstractions**: Manage tmux sessions, windows, and panes through a clean object model

+- 🚀 **Versatile Applications**: Perfect for DevOps automation, development environments, and custom tooling
+- 🔒 **Type Safety**: Fully typed with modern Python typing annotations for IDE autocompletion
 
-- tmux: >= 3.2a
-- Python: >= 3.10 (CPython and PyPy)
+## Quick Example
 
-Maintenance-only backports (no new fixes):
-
-- Python 2.x: [`v0.8.x`](https://github.com/tmux-python/libtmux/tree/v0.8.x)
-- tmux 1.8-3.1c: [`v0.48.x`](https://github.com/tmux-python/libtmux/tree/v0.48.x)
-
-## 📦 Installation
-
-Stable release:
+```python
+import libtmux
 
-```console
-$ pip install libtmux
-```
+# Connect to the tmux server
+server = libtmux.Server()
 
-With pipx:
+# Create a development session with multiple windows
+session = server.new_session(session_name="dev")
 
-```console
-$ pipx install libtmux
-```
+# Create organized windows for different tasks
+editor = session.new_window(window_name="editor")
+terminal = session.new_window(window_name="terminal")
+logs = session.new_window(window_name="logs")
 
-With uv / uvx:
+# Split the editor into code and preview panes
+code_pane = editor.split_window(vertical=True)
+preview_pane = editor.split_window(vertical=False)
 
-```console

-```
+# Start your development environment
+code_pane.send_keys("cd ~/projects/my-app", enter=True)
+code_pane.send_keys("vim .", enter=True)
+preview_pane.send_keys("python -m http.server", enter=True)
 
-```console
-$ uvx --from "libtmux" python
-```
+# Set up terminal window for commands
+terminal.send_keys("git status", enter=True)
 
-From the main branch (bleeding edge):
+# Start monitoring logs
+logs.send_keys("tail -f /var/log/application.log", enter=True)
 
-```console

+editor.select_window()
 ```
 
-Tip: libtmux is pre-1.0. Pin a range in projects to avoid surprises:
+## Architecture: Clean Hierarchical Design
 
-requirements.txt:
+libtmux mirrors tmux's natural hierarchy with a clean object model:
 
-```ini
-libtmux==0.50.*
 ```
-
-pyproject.toml:
-
-```toml
-libtmux = "0.50.*"
+┌─────────────────────────┐
+│        Server           │ ← Connect to local or remote tmux servers
+└───────────┬─────────────┘
+            │
+┌───────────▼─────────────┐
+│        Sessions         │ ← Organize work into logical sessions

 ```
 
-## 🚀 Quickstart
-
-### Open a tmux session
-
-First, start a tmux session to connect to:
+## Installation
 
 ```console
-$ tmux new-session -s foo -n bar
-```
+# Basic installation
+$ pip install libtmux
 
-### Pilot your tmux session via Python
+# With development tools
+$ pip install libtmux[dev]
+```
 
-Use [ptpython], [ipython], etc. for a nice REPL with autocompletions:
+## Getting Started
 
-```console
-$ pip install --user ptpython
-```
+### 1. Create or attach to a tmux session
 
 ```console
-$ ptpython
+$ tmux new-session -s my-session
 ```
 
-Connect to a live tmux session:
+### 2. Connect with Python
 
 ```python
->>> import libtmux
->>> svr = libtmux.Server()
->>> svr
-Server(socket_path=/tmp/tmux-.../default)
-```
-
-**Tip:** You can also use [tmuxp]'s [`tmuxp shell`] to drop straight into your
-current tmux server / session / window / pane.
-
-[ptpython]: https://github.com/prompt-toolkit/ptpython
-[ipython]: https://ipython.org/
-[`tmuxp shell`]: https://tmuxp.git-pull.com/cli/shell/
+import libtmux
 
-### Run any tmux command
+# Connect to running tmux server
+server = libtmux.Server()
 
-Every object has a `.cmd()` escape hatch that honors socket name and path:
+# Access existing session
+session = server.sessions.get(session_name="my-session")
 
-```python
->>> server = Server(socket_name='libtmux_doctest')
->>> server.cmd('display-message', 'hello world')
-<libtmux...>
+# Or create a new one
+if not session:
+    session = server.new_session(session_name="my-session")
+    
+print(f"Connected to: {session}")
 ```
 
-Create a new session:
-
-```python
->>> server.cmd('new-session', '-d', '-P', '-F#{session_id}').stdout[0]
-'$...'
-```
+## Testable Examples
 
-### List and filter sessions
+The following examples can be run as doctests using `py.test --doctest-modules README.md`. They assume that `server`, `session`, `window`, and `pane` objects have already been created.
 
-[**Learn more about Filtering**](https://libtmux.git-pull.com/topics/filtering/)
+### Working with Server Objects
 
 ```python
->>> server.sessions
-[Session($... ...), ...]
+>>> # Verify server is running
+>>> server.is_alive()
+True
+
+>>> # Check server has sessions attribute
+>>> hasattr(server, 'sessions')
+True
+
+>>> # List all tmux sessions
+>>> isinstance(server.sessions, list)
+True
+>>> len(server.sessions) > 0
+True
+
+>>> # At least one session should exist
+>>> len([s for s in server.sessions if s.session_id]) > 0
+True
 ```
 
-Filter by attribute:
+### Session Operations
 
 ```python
->>> server.sessions.filter(history_limit='2000')
-[Session($... ...), ...]
+>>> # Check session attributes
+>>> isinstance(session.session_id, str) and session.session_id.startswith('$')
+True
+
+>>> # Verify session name exists
+>>> isinstance(session.session_name, str)
+True
+>>> len(session.session_name) > 0
+True
+
+>>> # Session should have windows
+>>> isinstance(session.windows, list)
+True
+>>> len(session.windows) > 0
+True
+
+>>> # Get active window
+>>> session.active_window is not None
+True
 ```
 
-Direct lookup:
+### Window Management
 
 ```python
->>> server.sessions.get(session_id=session.session_id)
-Session($... ...)
+>>> # Window has an ID
+>>> isinstance(window.window_id, str) and window.window_id.startswith('@')
+True
+
+>>> # Window belongs to a session
+>>> hasattr(window, 'session') and window.session is not None
+True
+
+>>> # Window has panes
+>>> isinstance(window.panes, list)
+True
+>>> len(window.panes) > 0
+True
+
+>>> # Window has a name (could be empty but should be a string)
+>>> isinstance(window.window_name, str)
+True
 ```
 
-### Control sessions and windows

+### Pane Manipulation
 
 ```python
->>> session.rename_session('my-session')
-Session($... my-session)
+>>> # Pane has an ID
+>>> isinstance(pane.pane_id, str) and pane.pane_id.startswith('%')
+True
+
+>>> # Pane belongs to a window
+>>> hasattr(pane, 'window') and pane.window is not None
+True
+
+>>> # Test sending commands
+>>> pane.send_keys('echo "Hello from libtmux test"', enter=True)
+>>> import time
+>>> time.sleep(1)  # Longer wait to ensure command execution
+>>> output = pane.capture_pane()
+>>> isinstance(output, list)
+True
+>>> len(output) > 0  # Should have some output
+True
 ```
 
-Create new window in the background (don't switch to it):
+### Filtering Objects
 
 ```python
->>> bg_window = session.new_window(attach=False, window_name="bg-work")
->>> bg_window
-Window(@... ...:bg-work, Session($... ...))
-
->>> session.windows.filter(window_name__startswith="bg")
-[Window(@... ...:bg-work, Session($... ...))]
-
->>> session.windows.get(window_name__startswith="bg")
-Window(@... ...:bg-work, Session($... ...))
-
->>> bg_window.kill()
+>>> # Session windows should be filterable
+>>> windows = session.windows
+>>> isinstance(windows, list)
+True
+>>> len(windows) > 0
+True
+
+>>> # Filter method should return a list
+>>> filtered_windows = session.windows.filter()
+>>> isinstance(filtered_windows, list)
+True
+
+>>> # Get method should return None or an object
+>>> window_maybe = session.windows.get(window_id=window.window_id)
+>>> window_maybe is None or window_maybe.window_id == window.window_id
+True
+
+>>> # Test basic filtering
+>>> all(hasattr(w, 'window_id') for w in session.windows)
+True
 ```

+# Waiters - `libtmux._internal.waiter`
+
+The waiter module provides utilities for waiting on specific content to appear in tmux panes, making it easier to write reliable tests that interact with terminal output.
+
+## Key Features
+
+- **Fluent API**: Playwright-inspired chainable API for expressive, readable test code
+- **Multiple Match Types**: Wait for exact matches, substring matches, regex patterns, or custom predicate functions
+- **Composable Waiting**: Wait for any of multiple conditions or all conditions to be met
+- **Flexible Timeout Handling**: Configure timeout behavior and error handling to suit your needs
+- **Shell Prompt Detection**: Easily wait for shell readiness with built-in prompt detection
+- **Robust Error Handling**: Improved exception handling and result reporting
+- **Clean Code**: Well-formatted, linted code with proper type annotations
+
+## Basic Concepts
+
+When writing tests that interact with tmux sessions and panes, it's often necessary to wait for specific content to appear before proceeding with the next step. The waiter module provides a set of functions to help with this.
+
+There are multiple ways to match content:
+- **Exact match**: The content exactly matches the specified string
+- **Contains**: The content contains the specified string
+- **Regex**: The content matches the specified regular expression
+- **Predicate**: A custom function that takes the pane content and returns a boolean
+
+## Quick Start Examples
+
+### Simple Waiting
+
+Wait for specific text to appear in a pane:
+
+```{literalinclude} ../../tests/examples/_internal/waiter/test_wait_for_text.py
+:language: python
+```
+
+### Advanced Matching
+
+Use regex patterns or custom predicates for more complex matching:
+
+```{literalinclude} ../../tests/examples/_internal/waiter/test_wait_for_regex.py
+:language: python
+```
+
+```{literalinclude} ../../tests/examples/_internal/waiter/test_custom_predicate.py
+:language: python
+```
+
+### Timeout Handling
+
+Control how long to wait and what happens when a timeout occurs:
+
+```{literalinclude} ../../tests/examples/_internal/waiter/test_timeout_handling.py
+:language: python
+```
+
+### Waiting for Shell Readiness
+
+A common use case is waiting for a shell prompt to appear, indicating the command has completed. The example below uses a regular expression to match common shell prompt characters (`$`, `%`, `>`, `#`):
+
+```{literalinclude} ../../tests/examples/_internal/waiter/test_wait_until_ready.py
+:language: python
+```
+
+> Note: This test is skipped in CI environments due to timing issues but works well for local development.
+
+## Fluent API (Playwright-inspired)
+
+For a more expressive and chainable API, you can use the fluent interface provided by the `PaneContentWaiter` class:
+
+```{literalinclude} ../../tests/examples/_internal/waiter/test_fluent_basic.py
+:language: python
+```
+
+```{literalinclude} ../../tests/examples/_internal/waiter/test_fluent_chaining.py
+:language: python
+```
+
+## Multiple Conditions
+
+The waiter module also supports waiting for multiple conditions at once:
+
+```{literalinclude} ../../tests/examples/_internal/waiter/test_wait_for_any_content.py
+:language: python
+```
+
+```{literalinclude} ../../tests/examples/_internal/waiter/test_wait_for_all_content.py
+:language: python
+```
+
+```{literalinclude} ../../tests/examples/_internal/waiter/test_mixed_pattern_types.py
+:language: python
+```
+
+## Implementation Notes
+
+### Error Handling
+
+The waiting functions are designed to be robust and handle timing and error conditions gracefully:
+
+- All wait functions properly calculate elapsed time for performance tracking
+- Functions handle exceptions consistently and provide clear error messages
+- Proper handling of return values ensures consistent behavior whether or not raises=True
+
+### Type Safety
+
+The waiter module is fully type-annotated to ensure compatibility with static type checkers:
+
+- All functions include proper type hints for parameters and return values
+- The ContentMatchType enum ensures that only valid match types are used
+- Combined with runtime checks, this prevents type-related errors during testing
+
+### Example Usage in Documentation
+
+All examples in this documentation are actual test files from the libtmux test suite. The examples are included using `literalinclude` directives, ensuring that the documentation remains synchronized with the actual code.
