The first step to take before adding organisation information is to log-in.
After you've logged in, click the 'cog' at the top right of the screen, and you'll be able to see a list of all organisations you belong to.
Click the organisation you wish to add organisation information to.
You will then be taken through to the organisations' admin screens, where, if you have the correct permissions, you will be able to perform lots of different actions. To add organisation information, click the 'Edit Details' tile.
You will then have the option to input organisation information into relevant fields, including your email address, Facebook URL, Twitter username, and an organisation description. Don't forget to upload a logo as well!
When you are done, click the 'Save' button, located at the bottom left of the screen. Your changes will then be applied, and a 'Changes saved' notification will appear at the top of the page, as below.
