+Creation of your first instance
+===============================
+
+Instance creation
+-----------------
+
+Now that we created a cube, we can create an instance and access it via a web
+browser. We will use a `all-in-one` configuration to simplify things ::
+
+  cubicweb-ctl create -c all-in-one mycube myinstance
+
+.. note::
+  Please note that we created a new cube for a demo purposes but
+  you could have used an existing cube available in our standard library
+  such as blog or person for example.
+
+A series of questions will be prompted to you, the default answer is usually
+sufficient. You can anyway modify the configuration later on by editing
+configuration files. When a login/password are requested to access the database
+please use the credentials you created at the time you configured the database
+(:ref:`PostgresqlConfiguration`).
+
+It is important to distinguish here the user used to access the database and the
+user used to login to the cubicweb instance. When an instance starts, it uses
+the login/password for the database to get the schema and handle low level
+transaction. But, when :command:`cubicweb-ctl create` asks for a manager
+login/psswd of *CubicWeb*, it refers to the user you will use during the
+development to administrate your web instance. It will be possible, later on,
+to use this user to create other users for your final web instance.
+
+
+Instance administration
+-----------------------
+
+start / stop
+~~~~~~~~~~~~
+
+When this command is completed, the definition of your instance is
+located in :file:`~/etc/cubicweb.d/myinstance/*`. To launch it, you
+just type ::
+
+  cubicweb-ctl start -D myinstance
+
+The option `-D` specifies the *debug mode* : the instance is not
+running in server mode and does not disconnect from the terminal,
+which simplifies debugging in case the instance is not properly
+launched. You can see how it looks by visiting the URL
+`http://localhost:8080` (the port number depends of your
+configuration). To login, please use the cubicweb administrator
+login/password you defined when you created the instance.
+
+To shutdown the instance, Crtl-C in the terminal window is enough.
+If you did not use the option `-D`, then type ::
+
+  cubicweb-ctl stop myinstance
+
+This is it! All is settled down to start developping your data model...
+
+.. note::
+
+  The output of `cubicweb-ctl start -D myinstance` can be
+  overwhelming. It is possible to reduce the log level with the
+  `--loglevel` parameter as in `cubicweb-ctl start -D myinstance -l
+  info` to filter out all logs under `info` gravity.
+
+upgrade
+~~~~~~~
+
+A manual upgrade step is necessary whenever a new version of CubicWeb or
+a cube is installed, in order to synchronise the instance's
+configuration and schema with the new code.  The command is::
+
+  cubicweb-ctl upgrade myinstance
+
+A series of questions will be asked. It always starts with a proposal
+to make a backup of your sources (where it applies). Unless you know
+exactly what you are doing (i.e. typically fiddling in debug mode, but
+definitely NOT migrating a production instance), you should answer YES
+to that.
+
+The remaining questions concern the migration steps of |cubicweb|,
+then of the cubes that form the whole application, in reverse
+dependency order.
+
+In principle, if the migration scripts have been properly written and
+tested, you should answer YES to all questions.
+
+Somtimes, typically while debugging a migration script, something goes
+wrong and the migration fails. Unfortunately the databse may be in an
+incoherent state. You have two options here:
+
+* fix the bug, restore the database and restart the migration process
+  from scratch (quite recommended in a production environement)
+
+* try to replay the migration up to the last successful commit, that
+  is answering NO to all questions up to the step that failed, and
+  finish by answering YES to the remaining questions.
