1. Activate the customer plug-in 
2. Log into translate5 with PM rights
3. Create a customer
4. Import terminology to a termCollection by activating and using the TermImport plug-in (and at the same time assign the termCollection to customer). The TermImport at the current stage is the  only possibility to import Terminology into translate5's termCollection.
5. Switch to user management
6. Assign the customer to a user
7. Assign the role TermPortal to the user

For usage first terminology must be imported into termCollections of translate5 and the termCollections must be assigned to a customer.

Give a reasonable name to term attributes and termEntry attributes

At first after an import term attributes show up in the front end with exactly the  same names, they have in the imported TBX file.

This might not be good for end users in most of the cases.

Another name can be assigned by adding a value in the column "labelText" in the DB table LEK_term_attributes_label of translate5. This has to be done only once for each attribute name. Currently this is the only way to give a better name / label to term attributes in translate5.
