+Development versions
+~~~~~~~~~~~~~~~~~~~~
+
+``tt install`` can be used to build custom Tarantool and ``tt`` versions for
+development purposes from commits and pull requests on their GitHub repositories.
+
+To build Tarantool or ``tt`` from a specific commit on their GitHub repository,
+pass the commit hash (7 or more characters) after the program name. If you want to use

+
+    $ tt install tarantool 03c184d
+    $ tt install tt pr/50
+
+If you :ref:`build Tarantool from sources <building_from_source>`, you can install
+local builds to the current ``tt`` environment by running ``tt install`` with
+the ``tarantool-dev`` program name and the path to the build:
+
+..  code-block:: console
+
+    $ tt install tarantool-dev ~/src/tarantool/build
+
+Local repositories
+~~~~~~~~~~~~~~~~~~
+
 You can also set up a local repository with installation files you need.
 To use it, specify its location in the :ref:`repo section <tt-config_file_repo>`
 of the ``tt`` configuration file and run ``tt install`` with the ``--local-repo`` flag.
