-# Import from Trello
+# Importing from Trello
 
-It's already available in Planka, or you can also use the great tool [trello2planka](https://github.com/christophenne/trello2planka) to do the import.
+Planka supports importing data from a single Trello board in JSON format. Here's how to do it:
+
+## 1. Exporting from Trello:
+
+First, you'll need to export your Trello board data as a JSON file. Head over to Trello's documentation for instructions on exporting data: [support.atlassian.com/trello/docs/exporting-data-from-trello/](https://support.atlassian.com/trello/docs/exporting-data-from-trello/).
+
+## 2. Importing into Planka:
+
+- Open a project in Planka.
+- Create a new board and select a name.
+- Click the Import button.
+- Select Trello as the import source.
+- Choose the downloaded JSON file from your computer.
+
+Important Notes:
+
+If you're running Planka without SSL encryption, Chrome might block access to your file system.
+User information and attachments from Trello won't be imported during the Planka import process.
+Currently, Planka can only import one checklist per card.
+
+## Looking for More Features?
