+
+Details
+-------
+
+When called without an explicitly specified version, ``tt install`` installs the
+latest available version. To check versions available for installation, use
+:doc:`tt search <search>`.
+
+By default, available versions of Tarantool CE and ``tt`` are taken from their git repositories.
+Their installation includes building from sources, which requires some tools and
+dependencies, such as a C compiler. Make sure they are available in the system.
+
+Tarantool EE is installed from prebuilt packages.
+
+You can also set up a local repository with installation files you need.
+To use it, specify its location in the :ref:`repo section` of the ``tt`` configuration
+file and run ``tt install`` with the ``--local-repo`` flag.
+
+To uninstall a Tarantool or ``tt`` version, use :doc:`tt uninstall <uninstall>`.
+
+Example
+--------
+
+*   Install the latest available version of Tarantool:
+
+    ..  code-block:: bash
+
+        tt install tarantool
+
+*   Install Tarantool 2.10.5 from the local repository:
+
+    ..  code-block:: bash
+
+        tt install tarantool=2.10.5 --local-repo
+
+*   Reinstall Tarantool 2.10.5:
