+# Identification
+
+This stage provides a ready-to-go form for users to identify themselves.
+
+## Options
+
+### User Fields
+
+Select which fields the user can use to identify themselves. Multiple fields can be specified and separated with a comma.
+Valid choices:
+
+- email
+- username
+
+### Template
+
+This specifies which template is rendered. Currently there are two templates.
+
+The `Login` template shows configured Sources below the login form, as well as linking to the defined Enrollment and Recovery flows.
+
+The `Recovery` template shows only the form.
+
+### Enrollment/Recovery Flow
+
+These fields specify if and which flows are linked on the form. The enrollment flow is linked as `Need an account? Sign up.`, and the recovery flow is linked as `Forgot username or password?`.

+# Invitation Stage
+
+This stage can be used to invite users. You can use this enroll users with preset values.
+
+If the option `Continue Flow without Invitation`, this stage will continue when no invitation token is present.
+
+If you want to check if a user has used an invitation within a policy, you can check `request.context.invitation_in_effect`.

+This stage uses a 6-digit Code with a 30 second time-drift. This is currently not changeable.

+# Prompt Stage
+
+This stage is used to show the user arbitrary prompts.
+
+## Prompt
+
+The prompt can be any of the following types:
+
+|          |                                                                  |
+|----------|------------------------------------------------------------------|
+| text     | Arbitrary text, no client-side validation is done.               |
+| email    | E-Mail input, requires a valid E-Mail adress                     |
+| password | Password Input                                                   |
+| number   | Number Input, any number is allowed                              |
+| checkbox | Simple Checkbox                                                  |
+| hidden   | Hidden Input field, allows for the pre-setting of default values |
+
+A Prompt has the following attributes:
+
+### `field_key`
+
+HTML name used for the prompt. This key is also used to later retrieve the data in expression policies:
+
+```jinja2
+{{ request.context.prompt_data.<field_key> }}
+```
+
+### `label`
+
+Label used to describe the Field. This might not be shown depending on the template selected.
+
+### `required`
+
+Flag that decides whether or not this field is required.
+
+### `placeholder`
+
+Field placeholder, shown within the input field. This field is also used by the `hidden` type as the actual value.
+
+### `order`
+
+Numerical index of the prompt. This applies to all stages this prompt is a part of.

+# Prompt Validation
+
+Further validation of prompts can be done using policies.
+
+To validate that two password fields are identical, create the following expression policy:
+
+```jinja2
+{% if request.context.prompt_data.password == request.context.prompt_data.password_repeat %}
+True
+{% else %}
+{% do pb_message("Passwords don't match.") %}
+False
+{% endif %}
+```
+This policy expects you two have two password fields with `field_key` set to `password` and `password_repeat`.
+
+Afterwards bind this policy to the prompt stage you want to validate.
