+TF-A Memory Layout Tool
+=======================
+
+TF-A's memory layout tool is a Python script for analyzing the virtual
+memory layout of TF-A builds.
+
+Prerequisites
+~~~~~~~~~~~~~
+
+#. Python (3.8 or later)
+#. `Poetry`_ Python package manager
+
+Getting Started
+~~~~~~~~~~~~~~~
+
+#. Install Poetry
+
+    .. code:: shell
+
+        curl -sSL https://install.python-poetry.org | python3 -
+
+#. Install the required packages
+
+    .. code:: shell
+
+        poetry install --with memory
+
+#. Verify that the tool runs in the installed virtual environment
+
+    .. code:: shell
+
+        poetry run memory --help
+
+Symbol Virtual Map
+~~~~~~~~~~~~~~~~~~
+
+The tool can be used to generate a visualisation of the symbol table. By
+default, it prints the symbols representing the start and end address of the
+main memory regions in an ELF file (i.e. text, bss, rodata) but can be modified
+to print any set of symbols.
+
+.. code:: shell
+
+    $ poetry run memory -s
+    build-path: build/fvp/release

+
+Addresses are displayed in hexadecimal by default but can be printed in decimal
+instead with the ``-d`` option.
+
+Because of the length of many of the symbols, the tool defaults to a text width
+of 120 chars. This can be increased if needed with the ``-w`` option.
