+## Builder
+
+### `buildRegex()` function
+
+```ts
+function buildRegex(sequence: RegexSequence): RegExp;
+
+function buildRegex(
+    flags: {
+        global?: boolean;
+        ignoreCase?: boolean;
+        multiline?: boolean;
+        hasIndices?: boolean;
+        sticky?: boolean;
+    },
+    sequence: RegexSequence
+): RegExp;
+```
+
+## Components
+
+### `capture()` component
+
+Captures, also known as capturing groups, are used to extract and store parts of the matched string for later use. 
+
+```ts
+function capture(
+    sequence: RegexSequence
+): Capture
+```
+
+### `choiceOf()` component
+
+```ts
+function choiceOf(
+    ...alternatives: RegexSequence[]
+): ChoiceOf {
+```
+
+The `choiceOf` (alternation) construct is used to match one out of several possible sequences. It functions similarly to a logical OR operator in programming. It can match simple string options as well as complex patterns.
+
+Example: `choiceOf("color", "colour")` matches either `color` or `colour` pattern.
+
+## Quantifiers
+
+### `zeroOrMore()` component
+
+```ts
+function zeroOrMore(
+    sequence: RegexSequence,
+): ZeroOrMore
+```
+
+### `oneOrMore()` component
+
+```ts
+function oneOrMore(
+    sequence: RegexSequence,
+): OneOrMore
+```
+
+### `optionally()` component
+
+```ts
+function optionally(
+    sequence: RegexSequence,
+): Optionally
+```
+
+### `repeat()` component
+
+```ts
+function repeat(
+    options: { count: number } | { min: number; max?: number },
+    sequence: RegexSequence,
+): Repeat
+```
+
+## Character classes
+
+Character classes are a set of characters that match any one of the characters in the set. 
+
+### Common character classess
+
+```ts
+const any: CharacterClass;
+const word: CharacterClass;
+const digit: CharacterClass;
+const whitespace: CharacterClass;
+```
+
+* `any` matches any character except newline characters.
+* `word` matches any word character (alphanumeric & underscore).
+* `digit` matches any digit.
+* `whitespace` matches any whitespace character (spaces, tabs, line breaks).
+
+### `anyOf()` component
+
+```ts
+function anyOf(
+    characters: string,
+): CharacterClass
+```
+
+The `anyOf` class matches any character present in the `character` string.
+
+Example: `anyOf('aeiou')` will match either `a`, `e`, `i` `o` or `u` characters.
+
+### `characterRange()` component
+
+```ts
+function characterRange(
+    start: string,
+    end: string,
+): CharacterClass
+```
+
+The `characterRange` class matches any character present in the range from `start` to `end` (inclusive).
+
+Examples:
+* `characterRange('a', 'z')` will match all lowercase characters from `a` to `z`.
+* `characterRange('A', 'Z')` will match all uppercase characters from `a` to `z`.
+* `characterRange('0', '9')` will match all digit characters from `0` to `9`.
+
+### `characterClass()` component
+
+```ts
+function characterClass(
+    ...elements: CharacterClass[],
+): CharacterClass
+```
+
+The `characterClass` component creates a new character class that includes all passed character classes.
+
+Example:
+* `characterClass(characterRange('a', 'f'), digit)` will match all lowercase hex digits (`0` to `9` and `a` to `f`).
+* `characterClass(characterRange('a', 'z'), digit, anyOf("._-"))` will match any digit, lowercase latin lettet from `a` to `z`, and either of `.`, `_`, and `-` characters.
+
+### `inverted()` component
+
+```ts
+function inverted(
+    element: CharacterClass,
+): CharacterClass
+```
+
+The `inverted` component creates a new character class that matches any character that is not present in the passed character class.
+
+Examples:
+* `inverted(digit)` matches any character that is not a digit
+* `inverted(anyOf('aeiou'))` matches any character that is not a lowercase vowel.
+
+
+
+## Anchors
+
+Anchors are special characters or sequences that specify positions in the input string, rather than matching specific characters.
+
+### Line start and end
+
+```ts
+const startOfString: Anchor; // Regex: ^
+const endOfString: Anchor; // Regex: $
+```
+
+The `startOfString` (regex: `^`) matches the start of a string (or line, if multiline mode is enabled).
+
+The `endOfString` (regex: `$`)  matches the end of a string (or line, if multiline mode is enabled).
