-  - The _order_ of the events listed in ```current.yml``` and ```past.yml``` dictates the _order_ displayed, please make sure to properly insert events.
+The list of events is driven by files in the ```_data``` folder - if you have an update for those things, just change the relevant data file (currently ```current.yml```, ```past.yml```, or ```closed.yml```) and send a PR.
+  - The _order_ of the events listed in the data files dictates the _order_ displayed, please make sure to properly insert events.
   - If possible, spell out the conference name and add the abbreviation. Otherwise just use the abbreviation:
     - Example: Workshop on Performance and Reliability (WOPR)
   - If the conference name has a colon (:), place the entire name in quotes. Otherwise this can cause build errors. 
     - Example: ```"test:fest 2099"``` or ```"IBCU: Workshop on Testing 2099"``` 
   - Include the year
     - Sometimes workshops use a version instead of a year
       - Example: Workshop on Performance and Reliability (WOPR) 24
+  - Closed conferences can use ```closed.yml``` and include:
+    - ```first_date``` for the first known event date
+    - ```last_date``` for the last known event date
   - Don't include the @ symbol for the twitter handle. If there is no twitter option, leave it blank
   - Optionally include a status such as:
     - CFP is open / closed (CFP == Call for Proposal)
