-## Applying
-Functions are applied by placing expressions after the function name, separated by whitespace, e.g.
-
-```javascript
-Math.pow(2, 10)
-```
-equivalent would be
-```haskell
-Number.pow 2.0 10.0
-```
-
-## Defining
-Parts of a function definition are:
-- type signature (optional)
-- 1 or more "implementations" of the type signature
-  - name
-  - 0 or more arguments
-  - function body
-
-### Type Signature
-Function type signatures follow the form `<name> :: <type>`, and are always the line immediately above the function implementations, e.g.
-
-this `add` has 2 `Int` arguments and returns an `Int`.
-
-```haskell
-add2 :: Int -> Int -> Int
--- ...
-```
-
-### Name
-function names can contain any alphanumeric character, `_`, `'` but the first character must be a lowercase alpha or `_`.
-
-### Arguments
-Arguments are space-separated, e.g.
-
-the first [[Int]] argument is bound to `a`, the second to `b`.
-```haskell
-add :: Int -> Int -> Int
-add a b = -- ...
-```
-
-### Body
-The expression returned by the function, e.g.
-
-```haskell
-add a b = a + b
-```
-
-### Multiple Implementations
-Functions may have multiple implementations that change behavior based on the shape of the arguments.
-
-This is _similar_ to method overloading in OOP languages, but differs in that the number of arguments and type of the arguments must be the same for all implementations.
-
-Functions can have any number of implementations, as long as all possible inputs are covered exhaustively.
-
-e.g.
-
-this implementation of [[Number]] division has 2 paths:
-- when the denominator is zero, yields `Infinity`
-- otherwise, performs the division
-```haskell
-div num 0.0 = infinity
-div num den = num / den
-```
-
-this is equivalent to
-```haskell
-div num den =
-  if den == 0.0 then
-    infinity 
-  else
-    num / den
-```
-
-### Guards
-Single function implementations may have guards, which allows for conditional checks on inputs (as opposed to structural pattern matching)
-
-This pattern often takes up less space than explicit [[if then else Expressions]]
-
-Guard patterns are placed after the function arguments and take the form `| <Boolean expr> = <body>`. There can be any number of guard patterns, as long as all cases are exhaustively covered.
-
-e.g.
-
-Strings can't be structurally pattern matched, so in order to ask if a string starts with a substring we need to call a function like `Data.String.Utils.startsWith`.
-
-We could do this with `if then else`:
-
-```haskell
-ensureLeadingSlash :: String -> String
-ensureLeadingSlash str =
-  if String.Util.startsWith "/" then
-    str
-  else
-    "/" <> str
-```
-
-Alternatively, we could implement this with guard patterns:
-```haskell
-ensureLeadingSlash :: String -> String
-ensureLeadingSlash str
-  | String.Util.startsWith "/" str = str
-  | otherwise = "/" <> str
-```
-
-When the first pattern `String.Util.startsWith "/" str` returns `true`, the function will use `... = str`. Otherwise, it will prepend `/` to `str`.
-
-> [!info]
-> `otherwise` is simply an alias for `true`, specifically for better-reading fallthrough guard patterns.
-
-## Currying
-Functions are curried in PureScript, meaning that "a function of 2 arguments" is actually "a function of 1 argument, returning a function of 1 argument."
-
-This allows you to call many functions point-free, and think in terms of "building up to a conclusion" rather than "i need everything at once."
-
-e.g.
-
-```haskell
-add :: Int -> Int -> Int
--- ... 
-
-add2 :: Int -> Int
-add2 n = add 2 n
-```
-
-is equivalent to
-```haskell
-add :: Int -> Int -> Int
--- ... 
-
-add2 :: Int -> Int
-add2 = add 2
-```
-
-Walking through this:
-
-`add` has type `Int -> Int -> Int`
-
-if we give `add` a single `Int` argument, it will return a function of type `Int -> Int`. This function is the "second half" of `add`, waiting for it's second argument. Since `Int -> Int` is the type of `add2`, we can simply say `add2 = add 2`.
-
-> [!info]
-> as a rule, any time a function's last argument is passed as the last argument to another function, you can remove both.
-> ```haskell
-> f a = g b c a
->

-> f a = g $ h a
-> ```
-> can be written as
-> ```haskell
-> f = g b c
-> 
-> g b c
-> 
-> f = g <<< h
-> ```

-## Working with Functions
-Functions being first-class citizens means that it's important that applying, extending and combining functions must be easy.
-
-
-### Composition 
-The most common pattern by far; piping the output of a function into the input of the next.
-
-```haskell
-compose :: forall a b c. (b -> c) -> (a -> b) -> (a -> c)
-compose g f a = g (f a)
-```
-
-`compose` (infix as `<<<`) accepts 2 functions; `f` which is `a -> b` and `g`; `b -> c`. `compose` returns a new function `a -> c` that "glues" the 2 functions together; piping the output of `f` into `g`.
-
-e.g.
-
-consider a function `normalizedPathSegments :: String -> Array String`
-
-This function would normalize a file path, removing trailing / leading slashes and resolving relative paths, then split the path by its segments.
-
-A very good approach would be to split this function into separate single-purpose components, e.g.
-

-- `stripTrailingSlash :: String -> String`
-- `splitPath :: String -> Array String`
-- `normalizePathSegments :: Array String -> Array String`

-Infix operators are symbols that alias binary (2-argument) [[Functions|functions]].

-infixl <precedence> <fn> as <operator>
--- or

-```
-
-e.g.

-Operators are either left or right associative (`infixl` or `infixr`).

-## Directionality
-Most commonly used operators have flipped variants, e.g.
-- function composition has `g <<< f` or `f >>> g`
-- function application has `f $ a` or `a # f`
-- [[Functor|map]] has `f <$> a` or `a <#> f`
-- [[Bind|bind]] has `f =<< m` or `m >>= f`
-
-In general, right-to-left operators tend to be easier to refactor into & out of because they closely mirror the expressions they replace:
-
-```haskell
-map (add 1) maybeNum
--- into
-add 1 <$> maybeNum
-
-foo (bar a)
--- into
-foo <<< bar
-```
-
-Left-to-right, on the other hand, can read better to humans and plays better with pipelines containing both [[Bind|bind `>>=`]] and [[Functor|map `<#>`]].
-
-Consider an expression piping `Maybe String` to `split :: String -> Array String` then `Data.Array.NonEmpty.fromArray :: Array a -> Maybe (NonEmptyArray a)`, then `toLower` each element:
-
-```haskell
-String.toLower
-  <$> (
-    Array.NonEmpty.fromArray
-    =<< String.split "."
-    <$> mStr
-  )
-```
-
-We need to wrap the right hand of the last `map` because the precedence of `=<<` is `1` (the lowest) and the precedence of `<$>` is `4`.
-
-Written RTL, though, gives:
-```haskell
-mStr
-  <#> String.split "."
-  >>= Array.NonEmpty.fromArray
-  <#> String.toLower
-```
-
-This works because `<#>`'s precedence (1) is the same as `>>=`. The lower precedence on flipped map means you'll often need more parentheses wrapping its arguments `(..) <#> (..) >>= (..)` as opposed to entire expressions `.. <$> (.. =<< ..)`.
-
-Personally, I try to stick to RTL except for expressions including bind.

+Type signatures are written with [hindley-milner syntax](https://en.wikipedia.org/wiki/Hindley%E2%80%93Milner_type_system).
+
+They take the form
+```text
+{function} :: {type variables} {constraints} {arguments} {return type}
+```
+
+where:
+- `{function}` is the [[Functions|function]] name
+- `{type variables}` defines a list of type variables that are initially unconstrained; they could be literally anything.
+- `{constraints}` is a list of 0 or more [[Typeclasses|typeclass]] constraints that need to be met in order to apply the function
+- `{arguments}` is a list of 0 or more arguments
+- `{return type}` is the type returned by the function
+
+### Type Variables
+Type variables are a list of camelCase generic type parameters.
+
+```text
+forall a.
+```
+Defines 1 type variable `a`.
+
+```text
+forall a b c.
+```
+Defines 3 type variables `a`, `b` and `c`.

+### Constraints
+List of typeclass constraints that must be true in order to apply the function, separated by `=>`

+for any `a` that is `Show`able
