Using OGotcha is really easy, it involves 3 small steps:

1. The first thing you'll need to do is open the combat report you want to convert or the preview message.
   When it's open hover the API button in the report.
   Select the key completely and copy it (hint: use the shortcut Ctrl+c).
   
   
2. When you're at the homepage of OGotcha you need to paste the `CR-KEY` into the textfield.
   The textfield contains a little hint on how to insert it.
   Click on the textfield and paste the key.
   
   
3. Now that you've pasted your `CR-KEY` you can convert your combat report.
   You can use a few options before converting your report.
   These options give you the possibility to add Harvest reports & Flight costs (Deuterium cost) and much more.
