-## Configuration
-To enable the `workday` sensor in your installation, add the following to your `configuration.yaml` file:
-
-```yaml
-# Example configuration.yaml entry
-binary_sensor:
-  - platform: workday
-    country: DE
-```
-
-{% configuration %}
-name:
-  description: A name for this sensor.
-  required: false
-  type: string
-  default: Workday Sensor
-country:
-  description: >
-    Country code according to [holidays](https://pypi.org/project/holidays/) notation.
-  required: true
-  type: string
-province:
-  description: Subdivision code according to [holidays](https://pypi.org/project/holidays/) notation.
-  required: false
-  type: string
-workdays:
-  description: List of workdays.
-  required: false
-  type: list
-  default: "[mon, tue, wed, thu, fri]"
-excludes:
-  description: List of workday excludes.
-  required: false
-  type: list
-  default: "[sat, sun, holiday]"
-days_offset:
-  description: Set days offset (e.g., -1 for yesterday, 1 for tomorrow).
-  required: false
-  type: integer
-  default: 0
-add_holidays:
-  description: "Add custom holidays (such as company, personal holidays or vacations). Needs to formatted as `YYYY-MM-DD`."
-  required: false
-  type: list
-remove_holidays:
-  description: "Remove holidays (treat holiday as workday). Can be formatted as `YYYY-MM-DD` or by name for a partial string match (e.g. Thanksgiving)."
-  required: false
-  type: list
-{% endconfiguration %}
+{% include integrations/config_flow.md %}
 
 Days are specified as follows: `mon`, `tue`, `wed`, `thu`, `fri`, `sat`, `sun`.
 The keyword `holiday` is used for public holidays identified by the holidays module.
 
 <div class='note warning'>
 
-If you use the sensor for Norway (`NO`) you need to wrap `NO` in quotes or write the name in full.
-Otherwise, the value is evaluated as `false`.
-If you use the sensor for Canada (`CA`) with Ontario (`ON`) as `province:` then you need to wrap `ON` in quotes.
-Otherwise, the value is evaluated as `true` (check the YAML documentation for further details) and the sensor will not work.
-
-One other thing to watch is how the `holiday` keyword is used. Your first instinct might be to add it to the `exclude` configuration, thinking that it means to skip the holidays. Actually it means to exclude the days in the holidays list from the workdays. So, when you exclude `holiday` and a workday falls on that day, then that workday is excluded, and the sensor will be **off**. If you want every workday flagged with no regard to holidays, make sure that there is something in your `Excludes` configuration _other_ than `holiday`.

-## Full examples
+## Specific field information
 
-This example excludes Saturdays and Sundays but not pre-configured holidays. Two custom holidays are added.
+Country code must be given according to [holidays](https://pypi.org/project/holidays/) notation.
 
-```yaml
-# Example 1 configuration.yaml entry
-binary_sensor:
-  - platform: workday
-    country: US
-    workdays: [mon, tue, wed, thu, fri]
-    excludes: [sat, sun]
-    add_holidays:
-      - "2020-02-24"
-      - "2020-04-25"
-```
+Subdivision code must be given according to [holidays](https://pypi.org/project/holidays/) notation.
 
-This example excludes Saturdays, Sundays and holidays. One custom holiday is added.
-The date February 24th, 2020 is a Monday, but will be excluded (the sensor will be **off**) because it was added to the `add_holidays` configuration.
+Add holidays will only take dates formatted with `YYYY-MM-DD`.
 
-```yaml
-# Example 2 configuration.yaml entry
-binary_sensor:
-  - platform: workday
-    country: DE
-    workdays: [mon, tue, wed, thu, fri]
-    excludes: [sat, sun, holiday]
-    add_holidays:
-      - '2020-02-24'
-```
-
-This example excludes Saturdays, Sundays and holidays. Two holidays are removed: November 26, 2020 and December 25, 2020.
-
-```yaml
-# Example 3 configuration.yaml entry
-binary_sensor:
-  - platform: workday
-    country: US
-    workdays: [mon, tue, wed, thu, fri]
-    excludes: [sat, sun, holiday]
-    remove_holidays:
-      - '2020-11-26'
-      - '2020-12-25'
-```
-

-
-```yaml
-# Example 4 configuration.yaml entry
-binary_sensor:
-  - platform: workday
-    country: US
-    workdays: [mon, tue, wed, thu, fri]
-    excludes: [sat, sun, holiday]
-    remove_holidays:
-      - 'Thanksgiving'
-      - 'Christmas Day'
-```
+Remove holidays will take dates formatted with `YYYY-MM-DD` or partial of name, for example, `christmas` will exclude `Christmas Day`.
