Your Admin must have already integrated Rumi into Canvas.
To user Rumi in Canvas, classes and assignments must be created in Canvas, not Rumi.
This is a single-sign on integration, you should not register new accounts on Rumi.
Integration Steps
Step 1. Open Courses
Open Canvas → Click on Courses.
Step 2. Create/Select Assignment
Go to the “Assignments” section for a course and create a new assignment, or select an existing assignment if you already have one.
Step 3. Choose External Tool
In the “Submission Type” select “External Tool” and click the “Find” button next to the text field.
Step 4. Select Rumi
In the dialog choose Rumi, then click on Select. Do not check the "Load in new tab" if you wish to use the embedded version of Rumi.
Step 5. Save/Publish Assignment
Complete the rest of the Assignment Creation form and press “Save” or if the assignment hasn’t been published yet press “Save & Publish”.
Step 6. Student Rumi Redirect
Now students will see a section that redirects them to Rumi.
Note. IMPORTANT: Tell students to do all their writing in Rumi’s Editor, THEY SHOULD NOT use another editor (i.e. Google Docs or Word) to write their essay then paste in Rumi.
