 # How it works
 
-## Models
+Check out our [Wiki](https://github.com/eitchtee/WYGIWYH/wiki) for more information.
 
-### Transactions
-
-Transactions are the core feature of WYGIWYH, representing expenses or income in your accounts. Each transaction consists of the following fields:
-
-#### Type
-
-- **Income**: A positive amount entering your account
-- **Expense**: A negative amount exiting your account
-
-#### Paid Status
-
-A transaction can be either:
-
-- **Current**: When marked as paid
-- **Projected**: When marked as unpaid
-
-#### Account
-
-The account associated with the transaction. Required, limited to one account per transaction.
-
-#### Entity
-
-The party involved in the transaction:
-
-- For **Income**: The paying entity
-- For **Expense**: The receiving entity
-
-Optional field.
-
-#### Date
-
-The date when the transaction occurred. Required.
-
-#### Reference Date
-
-One of **WYGIWYH**'s key features. The reference date determines which month a transaction should count towards. For example, you can have a transaction that occurred on January 26th count towards February's finances.
-
-Optional - defaults to the transaction date's month if not specified.
-
-> [!CAUTION]
-> While designed primarily for credit card closing dates, this feature allows for debt rolling across months. Use responsibly to maintain accurate financial tracking.
-
-#### Type
-
-- Income, meaning a positive amount (usually) entering your account
-- Expense, meaning a negative amount exiting your account
-
-#### Description
-
-The name or purpose of the transaction. Required.
-
-#### Amount
-
-The monetary value of the transaction. Required.
-
-#### Category
-
-The primary classification of the transaction. Optional.
-
-#### Tags
-
-Additional labels for transaction categorization. Optional.
-
-#### Notes
-
-Additional information about the transaction. Optional.
-
-![img_4.png](.github/img/readme_transaction.png)
-
-### Installment Plan
-
-An Installment Plan is a helper model that generates a series of recurring transactions over a fixed period.
-
-#### Core Fields
-
-- **Account**: The account for all transactions in the plan. Required.
-- **Entity**: The paying or receiving party for all transactions. Optional.
-- **Description**: The name of the installment plan, used for all transactions. Required.
-- **Notes**: Additional information applied to all transactions. Optional.
-
-#### Installment Configuration
-
-- **Number of Installments**: Total number of transactions to create (e.g., 1/10, 2/10)
-- **Installment Start**: Initial counting point
-- **Start Date**: Date of the first transaction
-- **Reference Date**: Reference date for the first transaction
-- **Recurrence**: Frequency of transactions (e.g., Monthly)
-
-![img_1.png](.github/img/readme_installment_plan.png)
-
-### Transaction Details
-
-- **Amount**: Value for each transaction. Required.
-- **Category**: Primary classification for all transactions. Optional.
-- **Tags**: Labels applied to all transactions. Optional.
-
-### Recurring Transaction
-A Recurring Transaction is a helper model that generates recurring transactions indefinitely or until a certain date.
-
-#### Core Fields
-
-- **Account**: The account for all transactions in the plan. Required.
-- **Entity**: The paying or receiving party for all transactions. Optional.
-- **Description**: The name of the recurring transaction, used for all transactions. Required.
-- **Notes**: Additional information applied to all transactions. Optional.
-
-#### Recurring Transaction Configuration
-
-- **Start Date**: Date of the first transaction. Required.
-- **Reference Date**: Reference date for the first transaction. Optional.
-- **Recurrence Type**: Frequency of transactions (e.g., Monthly). Required.
-- **Recurrence Interval**: The interval between transactions (e.g. every 1 month, every 2 weeks, etc.). Required.
-- **End date**: When new transactions should stop being created. Optional.
-
-#### Transaction Details
-
-- **Amount**: Value for each transaction. Required.
-- **Category**: Primary classification for all transactions. Optional.
-- **Tags**: Labels applied to all transactions. Optional.
-
-#### Other information
-
-- Recurring transactions are checked and created every midnight using Procrastinate.
-- **WYGIWYH** tries to keep at most **6** future transactions created at any time.
-- If you delete a recurring transaction it will not be recreated.

-## Helper actions
-
-### Transfer
-
-A transfer happens when you move a monetary value from one account to another. This will create two transactions, one expense and one income with the values set by the user.
-
-Contrary to other finance trackers, due to our multi-currency support, **WYGIWYH**'s transfer system allows for non-zero transfers.
-
-![img.png](.github/img/readme_transfer.png)
-
-### Balance (Account Reconciliation)
-
-A balance is a easy way of updating your accounts balance. It creates a transaction with the difference between the balance currently in **WYGIWYH** and the new balance informed by you.
-
-This can be useful for savings accounts or other interest accruing investments.![img_2.png](.github/img/readme_balance.png)

-
-### API
-
-WYGIWYH has a comprehensive API, it's documentation can be accessed on `<your-wygiwyh-url>/api/docs/`
-
-> [!NOTE]
-> While the API works, there's still much to be added to it to equipare functionality with the main web app.
-
-### Transaction Rules
-
-Transaction Rules are a powerful feature in WYGIWYH that allow for automatic modification of transactions based on specified criteria. This can save time and ensure consistency in your financial tracking.
-
-Key Aspects of Transaction Rules:
-
-* **Conditions**: Set specific criteria that a transaction must meet for the rule to apply. This can include attributes like description, amount, account, etc.
-* **Actions**: Define what changes should be made to a transaction when the conditions are met. This can include setting categories, tags, or modifying other fields.
-* **Activation Options**: Rules can be set to apply when transactions are created, updated, or both.
-
-#### Actions and Conditions
-
-When creating a new rule, you will need to add a Condition and, later, Actions.
-
-Both use a limited subset of Python, via [SimpleEval](https://github.com/danthedeckie/simpleeval).
-
-The Condition must evaluate to True or False, and the Action must evaluate to a value that will be set on the selected field.
-
-You may use any of the available [variables](#available-variables) and [functions](#available-functions).
-
-#### Available variables
-
-* `account_name`
-* `account_id`
-* `account_group_name`
-* `account_group_id`
-* `is_asset_account`
-* `is_archived_account`
-* `category_name`
-* `category_id`
-* `tag_names`
-* `tag_ids`
-* `entities_names`
-* `entities_ids`
-* `is_expense`
-* `is_income`
-* `is_paid`
-* `description`
-* `amount`
-* `notes`
-* `date`
-* `reference_date`
-
-#### Available functions
-
-* `relativedelta`
-
-#### Examples
-
-Add a tag to an income transaction if it happens in a specific account
-
-```
-If...
-account_name == "My Investing Account" and is_income
-
-Then...
-Set Tags to
-tag_names + ["Yield"]
-```
-
----
-
-Move credit card transactions to next month when they happen at a cutoff date
-
-```
-If...
-account_name == "My credit card" and date.day >= 26 and reference_date.month == date.month
-
-Then...
-Set Reference Date to
-reference_date + relativedelta(months=1)).replace(day=1)
-```
