Use the navigation tree to find the topic you wish to edit (editing also implies writing about a topic for the first time). After clicking on the Edit button at the right top of the page, you will switch from View mode to Edit mode: the editing toolbar (“what you see is what you get editor”) similar to MS Word's toolbar will appear, and you will be able to add or edit text. When you finish editing, take some time to briefly describe what you did in Edit summary. If you wish to see the changes you've made to the text, use the Preview changes button. After doing that, click Save and close – your content will be saved and immediately visible to other Bumblehood users.
