+Linux Installation via Homebrew
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+EIM can also be installed on Linux using `Homebrew <https://brew.sh/>`_. This method works on most Linux distributions and is a good alternative if you prefer Homebrew over system package managers.
+
+First, install Homebrew if you have not already:
+
+.. code-block:: bash
+
+    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+
+Then add the Espressif tap and install EIM:
+
+.. code-block:: bash
+
+    # Add the Espressif tap
+    brew tap espressif/eim
+
+    # Install CLI only
+    brew install eim
+
+    # Or install GUI (includes CLI)
+    brew install --cask eim-gui
+
+To update EIM later:
+
+.. code-block:: bash
+
+    brew upgrade eim
+    # or
+    brew upgrade --cask eim-gui
+
+.. note::
+
+    The GUI version requires a graphical environment and may have additional dependencies depending on your Linux distribution.
