+### You must specify an integer as a key
+
+In `v0.8.1` we changed how link keys are handled (from timestamps to incremental integers).
+Take a look at `data/updates.txt` content.

+
+Try to delete it and refresh your page while being logged in.
+
+#### `updates.txt` doesn't exists or doesn't contain `updateMethodDatastoreIds`
+
+ 1. Create `data/updates.txt` if it doesn't exist.
+ 2. Paste this string in the update file `;updateMethodRenameDashTags;`
+ 3. Login to Shaarli.
+ 4. Delete the update file.
+ 5. Refresh.
