+# Boolean Values
+
+Boolean values have the type `Bool` and can be either `yes` ("true") or `no`
+("false").
+
+# Boolean Functions
+
+This documentation provides details on boolean functions available in the API.
+
+## `from_text`
+
+**Description:**
+Converts a string representation of a boolean value into a boolean. Acceptable
+boolean values are case-insensitive variations of `yes`/`no`, `y`/`n`,
+`true`/`false`, `on`/`off`.
+
+**Usage:**
+```tomo
+from_text(text: Text, success: Bool = !&Bool) -> Bool
+```
+
+**Parameters:**
+
+- `text`: The string containing the boolean value.
+- `success`: If provided, this boolean value reference will be set to `yes` if the given text is a recognizable boolean value or `no` otherwise.
+
+**Returns:**
+`yes` if the string matches a recognized truthy boolean value; otherwise return `no`.
+
+**Example:**
+```tomo
+Boo.from_text("yes") // yes
+from_text("no") // no
+from_text("maybe") // !&Bool (default value)
+```
+
+---
+
+## `random`
+
+**Description:**
+Generates a random boolean value based on a specified probability.
+
+**Usage:**
+```tomo
+random(p: Float = 0.5) -> Bool
+```
+
+**Parameters:**
+
+- `p`: The probability (between `0` and `1`) of returning `yes`. Default is `0.5`.
+
+**Returns:**
+`yes` with probability `p`, and `no` with probability `1 - p`.
+
+**Example:**
+```tomo
+random(0.7) // yes (with 70% probability)
+random(0.3) // no (with 70% probability)
+```
