 # mini-file-format
-minimalized ini
+
+Minimalized ini format with concrete format rules. Meant to be easily read and easily parsed.
+Ends with `.mini` i.e. `config.mini`.
+
+## Sections and Keys
+
+- Sections are denoted by square brackets (`[Section]`).
+- Subsections are nested within sections using dot notation (`[Section.Subsection]`).
+- All subsections must be explicitly defined before use.
+- Subsections can be empty.
+- Keys within sections or subsections use `key = value` syntax.
+- Key names may only contain `a-z`, `A-Z`, and `0-9`.
+- Empty keys (i.e., keys without values) are not allowed.
+- Spaces outside of strings are ignored.
+- Comments are denoted by `#` and may only appear on separate lines.
+
+## Supported Data Types
+
+The format supports the following data types:
+
+### Integer
+- Defined as a sequence of digits (`0-9`).
+- Example: `value = 5`
+
+### String
+- Strings are enclosed in double quotes (`""`).
+- Strings support escape sequences using backslashes (`\`).
+- Supported escape sequences:
+  - `\"` for a double quote (`"`)
+  - `\n` for a newline
+  - `\t` for a tab
+- Example: `string = "Line 1\nLine 2"`
+- Example: `string = "Tab\tSeparated"`
+- Example: `string = "My \"escaped\" String"`
+
+### Array
+- Arrays are enclosed in square brackets (`[]`) and contain comma-separated values.
+- Arrays may only contain one datatype.
+- Example: `array = [5, 6, 10]`
+
+### Boolean
+- Boolean values are represented as `true` or `false`.
+- Example: `myBool = false`
+
+### Floating-Point Numbers
+- Floating-point numbers use `.` for decimal notation or `e` for scientific notation.
+- Floats always end with `f`.
+- Floats may also be whole numbers without a decimal point.
+- Example: `anotherValue = 1.065f`
+- Example: `thisToo = 1e18f`
+- Example: `scientificFloat = 1.534e3f`
+- Example: `wholeFloat = 1f`
+
+### Hexadecimal Numbers
+- Hexadecimal numbers are prefixed with `0x`.
+- Example: `hexValue = 0xFA8`
+
+### Binary Numbers
+- Binary numbers are prefixed with `0b`.
+- Example: `binValue = 0b0010010`
+
+### Underscore in Numbers
+- Numbers can contain underscores (`_`) for readability.
+- Example: `anotherDec = 1_000_375`
+
+## Example Structure
+```text
+[Section]
+integer = 5
+string = "My String"
+array = [5, 6, 10]
+myBool = false
+
+# A comment
+[Section.Subsection]
+float = 1.065f
+float2 = 1e18f
+hexValue = 0xFA8
+
+[Section.Subsection.Subsection]
+binValue = 0b0010010
+anotherDec = 1_000_375
+```
