# The-Modding-Tree
The main way to add content is through creating layers. You can either add a layer directly in the layers object in layersSupportjs,
or declare it in another file and then do "`addLayer(layername, layerdata)`"
(good for breaking things up into smaller files). The existing layers are just examples and can be freely deleted.
You can use those as references and a base for your own layers.


**You will also need to add layer nodes to the tree in the HTML, look for where it says "Modify the tree in the table below!"** While you're there, you can also edit the modInfo at the top to change the name for your mod and some other settings. A unique modId will prevent your mod's saves from conflicting with other mods.


Most of the time, you won't need to dive deep into the code to create things, but you still can if you really want to.


The Modding Tree uses break_eternity.js to store large values. This means that many numbers are Decimal objects,
and must be treated differently. For example, you have to use `new Decimal(x)` to create a Decimal value instead of a
plain number, and perform operations on them by calling functions. e.g, instead of `x = x + y`, use `x = x.add(y)`.

                                                   You can even create entirely new components to use.
- [Subtabs and Microtabs](subtabs-and-microtabs.md): Create subtabs for your tabs, as well as "microtab" components that you can put inside the tabs.
