oh-my-zsh is fully configurable to your needs with the help of the `$ZSH_CUSTOM` variable, whether you want to change its internals, plugins or the rich theme set - and all that __without forking__!
oh-my-zsh is fully configurable to your needs with the help of the `$ZSH_CUSTOM` variable, whether you want to change its internals, plugins or the rich theme set - and all that **without forking**!
Initially `$ZSH_CUSTOM` points to oh-my-zsh's `custom` directory. Whatever you place inside of it will take precedence over the built-in configuration.
#### Overriding and adding plugins
Let's say you created your own plugin `foobar` and want to add it to your configuration.
``` bash
# your .zshrc
plugins=(git bundler foobar)
```
Let's say you created your own plugin `foobar` and want to add it to your configuration.\`\`` bash
your .zshrc
===========
plugins=(git bundler foobar)`
Create a `foobar` directory inside the `plugins` folder and an initialization script to launch your plugin. This script has to follow a naming convention, as all plugin files must have an ending of `.plugin.zsh`. Your file tree should look like this:
```
custom/
plugins/
foobar/
foobar.plugin.zsh
```
Also follow these steps if you want to override plugins that ship with your oh-my-zsh installation. In case it's the rvm plugin you want to override, create the directory `custom/plugins/rvm` and place a file called `rvm.plugin.zsh` inside of it.
` custom/ plugins/ foobar/ foobar.plugin.zsh\`\``
Also follow these steps if you want to override plugins that ship with your oh-my-zsh installation. In case it's the rvm plugin you want to override, create the directory`custom/plugins/rvm`and place a file called`rvm.plugin.zsh` inside of it.
A word of warning: None of the original rvm plugin files will get sourced if you define a custom rvm plugin. If you want to customize just a single public function of a plugin, use the approach as outlined in the section below that tells you about how to override internals.
#### Overriding and adding themes
Adding and customizing your own themes pretty much works the same as with plugins. Themes are located in a `themes` folder and must end with `.zsh-theme`.
```bash
custom/
themes/
my_awesome_theme.zsh-theme
# your .zshrc
ZSH_THEME="my_awesome_theme"
```
Remember that customizations always take precedence over built-ins. If you happen to enjoy a particular theme that comes packaged with oh-my-zsh, but would like to change just a little detail inside of it - let's say you love the `agnoster` theme, it will be the easiest to copy the `agnoster.zsh-theme` file to your `custom/themes` directory and customize it.

# your .zshrc ZSH_THEME="my_awesome_theme"\`\``

If you don't change its filename, your `.zshrc` file can stay the same: `ZSH_THEME="agnoster"` will be perfect and still take your changes into account. You might also want to consider this before filing a new issue or pull request that just changes a trivial detail inside of a built-in theme.
Hint: Using a random theme with `$ZSH_THEME="random"` will not look into your custom themes directory. Only built-in themes will be used.
#### Overriding internals
oh-my-zsh's internals are defined in its `lib` directory. To change them just create a file inside the `custom` directory (its name doesn't matter, as long as it has a `.zsh` ending) and start customizing whatever you want. Unsatisfied with the way `git_prompt_info()` works? Ride your own implementation!
``` bash
custom/
my_patches.zsh
# inside the file my_patches.zsh
function git_prompt_info() {
# prove that you can do better
}
```
Such customization files will always be the last thing that oh-my-zsh sources before handing over control to your terminal. Also use this approach if you want to override specific details of built-in plugins.

#### Using another customization directory
If you don't want to use the built-in `custom` directory itself, just change the path of `$ZSH_CUSTOM` inside your `.zshrc` to a directory of your own liking. Everything will be fine as long as you adhere to the conventional file hierarchy.
``` bash
# your .zshrc
ZSH_CUSTOM=$HOME/my_customizations
# file tree inside of your home directory
my_customizations/
plugins/
my_plugin/
my_plugin.plugin.zsh
themes/
my_theme.zsh-theme
my_lib_patches.zsh
```

# file tree inside of your home directory my_customizations/ plugins/ my_plugin/ my_plugin.plugin.zsh themes/ my_theme.zsh-theme my_lib_patches.zsh\`\`\`
### Version control of customizations
By default git is set to ignore the custom directory, so that oh-my-zsh's update process does not interfere with your customizations.
If you want to use a version control system like git for your personal changes, just initialize an own repository inside the `custom` directory (`git init`), or point `$ZSH_CUSTOM` to another directory you have under version control.
