+1. Events status
+================
+
+Status
+------
+
+Draft
+
+Context
+-------
+
+Each Open edX Event will evolve according to the needs of the community.
+For that reason, with this ADR, we attempt to define a lifecycle that each
+event will follow individually.
+
+Decision
+--------
+
+Each Open edX Event will follow the following lifecycle:
+
+State 1. Provisional
+~~~~~~~~~~~~~~~~~~~~
+
+Events just created and accepted in the repository `openedx-events`,
+these events haven't been accepted in Open edX platform or by the community.
+
+State 2. Active
+~~~~~~~~~~~~~~~
+
+Events being used by Open edX platform and by the community.
+
+State 3. Deprecated
+~~~~~~~~~~~~~~~~~~~
+
+Events that members of the community decide to deprecate in Open edX platform.
+
+State 4. Removed
+~~~~~~~~~~~~~~~~~
+
+Events that members of the community removed from Open edX platform after
+documentation and discussion of the removal.
+
+State 5. Replaced
+~~~~~~~~~~~~~~~~~
+
+Events that members of the community replaced for another event after
+documentation and discussion of the change.
+
+
+Consequences
+------------
+
+1. Each event must carry its state in its code-annotation documentation.
+
+2. Each event must go through each state in order. First, must be created
+in this repository with the state `provisional`, when Open edX accepts it
+must change to `active` and when the community decides to deprecate it, it
+must be updated to `deprecated`, then `removed` and `unused`.
+
+3. Each state must be up-to-date.
