+# Analytics in Element
+
+## Solution
+
+Element is using PostHog to send analytics event.
+We ask for the user to give consent before sending any analytics data.
+
+## How to add a new Event
+
+The analytics plan is shared between all Element clients. To add an Event, please open a PR to this project: https://github.com/matrix-org/matrix-analytics-events
+
+Then, once the PR has been merged, you can run the tool `import_analytic_plan.sh` to import the plan to Element, and then you can use the new Event. Note that this tool is run by Github action once a week.
+
+## Forks of Element
+
+Analytics on forks are disabled by default. Please refer to AnalyticsConfig and there implementation to setup analytics on your project.
