[IMP] developer/cli: mention the different ways of calling the CLI

All examples on the page suggest calling the CLI with "odoo-bin" while
it is recommended to call it with "odoo" when Odoo was installed from a
distribution package. It also failed to mention the location of
"odoo-bin" relative to the source files.

The chance is also taken to rename the somewhat unclear page title to
something more clear and generic.

+Command-line interface (CLI)
+============================
+
+The CLI :dfn:`command-line interface` offers several functionalities related to Odoo. You can use it
+to :ref:`run the server <reference/cmdline/server>`, :ref:`launch Odoo as a Python console
+environment <reference/cmdline/shell>`, :ref:`scaffold an Odoo module <reference/cmdline/scaffold>`,
+:ref:`populate a database <reference/cmdline/populate>`, or :ref:`count the number of lines of code
+<reference/cmdline/cloc>`.
+
+.. important::
+   The command to use to call the CLI depends on how you installed Odoo. In the examples below, we
+   assume that you are :ref:`running Odoo from source <setup/install/source>` with the
+   :file:`odoo-bin` file. If you installed Odoo :ref:`from a distribution package
+   <setup/install/packaged>` or :ref:`with Docker <setup/install/docker>`, you must adapt the
+   command.

+            Community.
+         #. Run all CLI commands with :command:`./odoo-bin`
+
+      .. tab:: Odoo was installed from a distribution package
+
+         When Odoo was installed, an executable named `odoo` was added to your user's PATH. Replace
+         all occurrences of :command:`odoo-bin` with :command:`odoo` in the examples below.
+
+      .. tab:: Odoo was installed with Docker
+
+         Please refer to the `documentation of the official Docker image of Odoo
+         <https://hub.docker.com/_/odoo/>`_.
