+# 8.x-2.0 Release Notes
+
+## Removing Gemini
+It is recommended to test this method in a staging/development environment before running in your production environment.
+1. Update islandora core (likely through a command like `composer update islandora/islandora`)
+2. Import two new Islandora views
+
+    i. This can be done by coping the views into a new directory and using drush such as 
+    ```
+    mkdir /var/www/html/drupal/config/1time
+    cp /var/www/html/drupal/web/modules/contrib/islandora/modules/islandora_core_feature/config/install/views.view.all_taxonomy_terms.yml /var/www/html/drupal/config/1time/
+    cp /var/www/html/drupal/web/modules/contrib/islandora/modules/islandora_core_feature/config/install/views.view.non_fedora_files.yml /var/www/html/drupal/config/1time/
+    drush config:import --partial --source /var/www/html/drupal/config/1time
+    ```
+    ii. It can also be done through the UI at `/admin/config/development/configuration/single/import`
+3. Update crayfish-commons for drupal with something like `cd /var/www/html/drupal && composer update islandora/crayfish-commons`
+4. Update Crayfish code (likely by traversing to your crayfish installation and doing a git pull `cd /var/www/html/Crayfish && git pull`)
+5. Run composer install for Milliner such as `cd /var/www/html/Crayfish/Milliner && composer install`
+6. Run composer install for Recast such as `cd /var/www/html/Crayfish/Recast && composer install`
+7. Update the Recast config 
+
+    i. `cd /var/www/html/Crayfish/Recast/cfg`
+    ii. open `config.yaml`
+    iii. Remove `gemini_base_url`
+    iv. Update `base_url` in `fedora_resource` section. It should contain a value something like `http://localhost:8080/fcrepo/rest`
+8. Clear your cache in Drupal. Potentially like `cd /var/www/html/drupal && drush cr`
+9. Restart apache (not 100% sure if this is necesssary) `sudo systemctl restart apache2`
+9. Test to make sure you can view existing objects in Fedora by going to the Drupal UI and clicking one of the Fedora URI links
+10. Create a new object and make sure it persists to Fedora and the Fedora URI likn resolves correctly. Make sure that no new entries get added to Gemini.
+11. If you're feeling brave, you can then remove Gemini like
+    i. `rm /var/www/html/Crayfish/Gemini`
+    ii. Remove the gemini database and the associated mysql user
+
+
+## Adding Captions
+1. Make sure you are on the most recent code of islandora and islandora_defaults (`composer update islandora/islandora islandora/islandora_defaults`)
+2. Do a config import on the `config/install` directory of `islandora_defaults` or copy the changed files into another directory and import those (if you are on an existing install, i'd recommend the partial config import). The changed files are:
+    i. core.entity_form_display.media.audio.default
+    ii. core.entity_form_display.media.video.default
+    iii. core.entity_view_display.media.audio.default
+    iv. core.entity_view_display.media.audio.source
+    v. core.entity_view_display.media.video.default
+    vi. core.entity_view_display.media.video.source
+    vii. field.field.media.audio.field_track
+    viii. field.field.media.video.field_track
+    ix. field.storage.media.field_track
+3. clear your drupal cache `drush cr`
+4. You should now see a "track" field on audio and video media objects
