  Keybinds\n    -   Start and End characters `{{` and `}}`\n-   Super expressive Expressions\n    -   Custom text functions\n    -   Nested expression\n    -   Preprocessors\n    -   Aliases\n-   Plugins\n    -   Custom Transformers\n    -   Define your own functions.\n-   **Work In Progress** Babel precompilation\n    -   Prevent infinite loops.\n    -   Use the newest js language features\n-   **Work In Progress** Error reporting\n\n### Sample Expressions\n\n-   `{{ 1 + 1 }}` =\u003e `2`\n    -   Most basic expression\n-   `{{ 1 + {{ 2 + 2 }} }}` =\u003e `5`\n    -   Nested expressions\n-   `{{1+{{2+2}}}}` =\u003e `5`\n    -   Expressions are free-form\n-   `{{!repeat 2 Hello World}}` =\u003e `Hello World Hello World`\n    -   Gets precompiled for convenients\n\t-   `repeat` is a custom text processing function.\n\tIt receives the string after the call, and in this case it parses the number and repeats the string.\n    -   Is equivalent to `{{repeat(\"2 Hello World\");}}`\n-   `1+1 = {{1+1}} :)` =\u003e `1+1 = 2 :)`\n    -   Expressions can be mixed with text\n\n## Build Instructions\n\n#### Setup guide.\n\n1. **Clone this repository to your local drive.**\n    -
