+Change settings by pressing `ctrl-p` to enter command mode and then typing `set <cmd name> <value>`. All settings remain for the duration of the editor session. When opening a new editor, the default configuration is used. 
+
+To change the default values, use the following in your `.juliarc.jl`:
+
+```
+using Acorn
+Acorn.configSet(:param_name, value)
+```
+where `:param_name` is a symbol with the parameter's name and `value` is the new default value.
+
+Acorn currently supports the following settings:
+
+  - `tab_stop`: Tab width in number of spaces. (default: 4,)
+  - `expandtab`: If true, insert spaces when pressing the tab key.
+  - `status_fullpath`: If true, display the full path to the file in the status bar. If false, just display the name.

+# Credits
+
+  - Much of the core code and design in `src/editor.jl` is based off of [antirez](http://invece.org/)'s [kilo](http://antirez.com/news/108). 
+  - The [kilo tutorial](http://viewsourcecode.org/snaptoken/kilo/) by [snaptoken](https://github.com/snaptoken) was a huge help when writing the core editor features.
