+# Dojo: a platform to practice programming
+
+The dojo platform is an online tool built to help practice programming by
+allowing users to propose assignments and perform them as exercises.
+
+The tool is very flexible and allows for proposing exercises for any language
+and does not impose any limitation on a framework to be heavily relying
+on Docker and Gitlab. These tools used in combination allow for automatic
+correction of assignments in order to give immediate feedback to users
+performing exercises. Solved exercises can then be shared among the community
+of users such that they can inspire other users or give hints on ways to solve
+a given exercise.
+
+The two major concepts of the platform are the **assignments** and the **exercises**.
+
+The principal way to interact with the Dojo platform is currently the `dojo` CLI.
+
+## The assignment
+
+An assignment is written by a user that wants to propose an exercise. It is typically composed of a written description of the work to be performed,
+and tests that must be passed once the exercise is successfully performed (and some configuration files for the infrastructure of the tests
+such as docker files). At its core, an assignment is
+nothing else than a git repository that can be forked in the form of an exercise and modified using standard git commands.
+For a more detailed description please see the [CLI documentation](home).
+An assignment can be proposed by any user.
+
+In the future a dependency tree of assignments can be created, as well as tagging for filtering purposes.
+
+## The exercise
+
+An exercise is an instance of an assignment which the learner will modify in order to make it pass the automatic tests.
+It can be run locally on any user's machine using the dojo CLI. When the exercise is completed
+it is pushed on the dojo where the CI/CD tools of Gitlab can evaluate it automatically and
+notify the dojo platform of the result. The exercises can then be shared with other users
+in order to propose a wide variety of solutions and can be a base for discussion among users
+and with teachers.
+For a more detailed description please see the [CLI documentation](home).
