-## 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)

-
-The calculator is a floating widget that can be toggled by clicking the calculator icon on the navbar.
-
-It allows for any math expression supported by [math.js](https://mathjs.org).
-

-
-### Dollar Cost Average Tracker
-
-The DCA Tracker can be accessed from the navbar's **Tools** menu.
-
-It allows for tracking DCA strategies and getting helpful information and insights.
-
-> [!IMPORTANT]
-> Currently DCA exists separately from your main transactions. You will need to add your entries manually.

-
-### Unit Price Calculator
-
-The Unit Price Calculator can be accessed from the navbar's **Tools** menu.
-
-This is a self-contained tool for comparing and finding the most cost-efficient item quickly and easily.
-
-Input the price and the amount of each item, the cheapeast will be highlighted in green, and the most expensive in red.
-
-You can add additional items by clicking the _Add_ button at the end of the page.
+You can now access localhost:OUTBOUND_PORT
 
 > [!NOTE]
-> This doesn't do unit convertion. The amount of all items needs to be on the same the unit for proper functioning.
+> - If you're planning on running this behind Tailscale or other similar service also add your machine given IP to `DJANGO_ALLOWED_HOSTS`
+> - If you're going to use another IP that isn't localhost, add it to `DJANGO_ALLOWED_HOSTS`, without `http://`

+## Latest changes
+Features are only added to `main` when ready, if you want to run the latest version, you must build from source or use the `:nightly` tag on docker. Keep in mind that there can be undocumented breaking changes.

+All the required Dockerfiles are [here](https://github.com/eitchtee/WYGIWYH/tree/main/docker/prod).
+
+## Unraid
+
+[nwithan8](https://github.com/nwithan8) has kindly provided a Unraid template for WYGIWYH, have a look at the [unraid_templates](https://github.com/nwithan8/unraid_templates) repo.
+
+WYGIWYH is available on the Unraid Store. You'll need to provision your own postgres (version 15 or up) database.
+
+To create the first user, open the container's console using Unraid's UI, by clicking on WYGIWYH icon on the Docker page and selecting `Console`, then type `python manage.py createsuperuser`, you'll them be prompted to input your e-mail and password.

+# Caveats and Warnings
+
+- I'm not an accountant, some terms and even calculations might be wrong. Make sure to open an issue if you see anything that could be improved.
+- Pretty much all calculations are done at run time, this can lead to some performance degradation. On my personal instance, I have 3000+ transactions over 4+ years and 4000+ exchange rates, and load times average at around 500ms for each page, not bad overall.
+- This isn't a budgeting or double-entry-accounting application, if you need those features there's a lot of options out there, if you really need them in WYGIWYH, open a discussion.
