+## Some words about how I maintain my journal
+
+I dislike mixing all user transactions with all the payee, account, automatic transaction definitions. What I usually do is to define a main file `main.ledger` whose content is
+
+```
+; This is main.ledger
+
+include definitions.ledger
+include current.ledger
+```
+
+In the same directory, I then have two other files `definition.ledger` and `current.ledger`. The first one keeps all commands and automatic transactions.
+
+```
+; This is definition.ledger
+
+account First account
+account Second account
+
+payee A payee
+
+tag aTag
+
+= /aReGeX/
+    First account     10 EUR
+    Second account   -10 EUR
+```
+
+The second one keeps all user transactions.
+
+```
+; This is current.ledger
+
+04/02/2021 A payee
+    First account     10 EUR
+    Second account   -10 EUR
+```
+
+**This distinction is important as the program looks for account, payee and automatic transaction definitions in `definition.ledger` to work. This file location should be given in the package settings**. 
+
+Note: This does not mean you can not mix the two files in a single one, but it means you have to define this single file as the definition file in the settings.

 ```
 
 In this list, the first two entries are denoted cleared with a star placed before the payee. The last one (Forno Gusto) is not cleared. This can mean whatever you want. In my case, I use it to denote the transactions that do not appear yet on my online bank register so that, when I type
+
 ```
 ledger balance Assets --real --cleared
 ```
+
 (notice the `--cleared` option), the Forno Gusto transaction is not taken into account and I get the same balance as my bank. That helps me to be sure not to make a mistake. When the transaction appear in my bank balance, I simply add a star. **Meanwhile, the pluggin highlights the entry which has not been cleared.** This helps to see imediatly which entries are still pending.
 
 **Notes:** 
 
 1. By default, Ledger consider all entries, even those which are not cleared. As a consequence, 
+
 ```
 ledger balance Assets --real
 ```
+
 would take the Forno Gusto transaction into account.

+## Automatic transaction notification
+
+Again, I usually use automatic transaction to maintain my Budget. For that, I define a lots of them in my definition file, like
+
+```
+= /Depenses:Food/
+    [Equity:Budgets]                                   1
+    [Assets:Budgets:Food]                             -1
+```
+
+The user transactions defined in the `current.ledger` file hiding an automatic transaction is notified with the hidden transaction detail.
