+Shell Command
+=============
+
+The ``micromamba shell`` command provides functionality for launching shells and managing shell initialization scripts for environment activation.
+
+Launching a Shell
+-----------------
+
+When used without subcommands, ``micromamba shell`` launches a new shell session in the specified environment:
+
+.. code-block:: shell
+
+    # Launch a shell in the specified environment
+    micromamba shell -p /path/to/env
+    micromamba shell -n myenv
+
+This is particularly useful in CI/CD environments and Docker containers where you need to work within a specific environment.
+
+Shell Initialization Management
+-------------------------------
+
+The ``micromamba shell`` command also includes several subcommands for managing shell initialization scripts:
+
+``micromamba shell init``
+    Add micromamba initialization scripts to your shell's configuration files (e.g., ``.bashrc``, ``.zshrc``).
+
+``micromamba shell deinit``
+    Remove micromamba initialization scripts from your shell's configuration files.
+
+``micromamba shell reinit``
+    Restore micromamba initialization scripts in your shell's configuration files.
+
+Environment Activation Scripts
+------------------------------
+
+These subcommands generate shell-specific activation code that can be used in scripts or sourced directly:
+
+``micromamba shell activate``
+    Generate activation code for the specified environment.
+
+``micromamba shell deactivate``
+    Generate deactivation code to leave the current environment.
+
+``micromamba shell reactivate``
+    Generate reactivation code to refresh the current environment.
+
+``micromamba shell hook``
+    Generate shell hook scripts for environment activation.
+
+.. code-block:: shell
+
+    # Generate activation code for bash
+    micromamba shell activate -p /path/to/env -s bash
+
+    # Generate deactivation code
+    micromamba shell deactivate -s bash
+
+    # Use in a script
+    eval "$(micromamba shell activate -p /path/to/env -s bash)"
+
+Supported Shells
+----------------
+
+The shell command supports the following shells:
+
+* ``bash`` - Bash shell
+* ``zsh`` - Z shell
+* ``fish`` - Fish shell
+* ``powershell`` - PowerShell
+* ``cmd.exe`` - Windows Command Prompt
+* ``xonsh`` - Xonsh shell
+* ``tcsh`` - Tcsh shell
+* ``dash`` - Dash shell
+* ``nu`` - Nu shell
+* ``posix`` - POSIX-compliant shells
+
+Common Options
+--------------
+
+``-s, --shell SHELL``
+    Specify the shell type. If not provided, micromamba will attempt to detect your shell automatically.
+
+``-p, --prefix PATH``
+    Specify the environment by its installation path.
+
+``-n, --name NAME``
+    Specify the environment by its name.
+
+``-r, --root-prefix PATH``
+    Specify the root prefix (base environment location).
+
+Platform-Specific Features
+---------------------------
+
+``micromamba shell enable_long_path_support``
+    On Windows, this command enables long path support, which allows working with file paths longer than 260 characters.
