+# TOML
+
+This module parse TOML files. It follows as much as possible the
+[TOML specs](https://github.com/toml-lang/toml). Be sure to read the supported
+types as not every specs is supported at the moment and the handling in
+TypeScript side is a bit different.
+
+## Supported types and handling
+
+- :heavy_check_mark: [Keys](https://github.com/toml-lang/toml#string)
+- :exclamation: [String](https://github.com/toml-lang/toml#string)
+- :heavy_check_mark:
+  [Multiline String](https://github.com/toml-lang/toml#string)
+- :heavy_check_mark: [Literal String](https://github.com/toml-lang/toml#string)
+- :exclamation: [Integer](https://github.com/toml-lang/toml#integer)
+- :heavy_check_mark: [Float](https://github.com/toml-lang/toml#float)
+- :heavy_check_mark: [Boolean](https://github.com/toml-lang/toml#boolean)
+- :heavy_check_mark:
+  [Offset Date-time](https://github.com/toml-lang/toml#offset-date-time)
+- :heavy_check_mark:
+  [Local Date-time](https://github.com/toml-lang/toml#local-date-time)
+- :heavy_check_mark: [Local Date](https://github.com/toml-lang/toml#local-date)
+- :exclamation: [Local Time](https://github.com/toml-lang/toml#local-time)
+- :heavy_check_mark: [Table](https://github.com/toml-lang/toml#table)
+- :heavy_check_mark: [Inline Table](https://github.com/toml-lang/toml#inline-table)
+- :exclamation: [Array of Tables](https://github.com/toml-lang/toml#array-of-tables)
+
+:exclamation: _Supported with warnings see [Warning](#Warning)._
+
+### :warning: Warning
+
+#### String
+
+- Regex : Due to the spec, there is no flag to detect regex properly
+  in a TOML declaration. So the regex is stored as string.
+
+#### Integer
+
+For **Binary** / **Octal** / **Hexadecimal** numbers,
+they are stored as string to be not interpreted as Decimal.
+
+#### Local Time
+
+Because local time does not exist in JavaScript, the local time is stored as a string.
+
+#### Inline Table
+
+Inline tables are supported. See below:
+
+```toml
+animal = { type = { name = "pug" } }
+# Output
+animal = { type.name = "pug" }
+# Output { animal : { type : { name : "pug" } }
+animal.as.leaders = "tosin"
+# Output { animal: { as: { leaders: "tosin" } } }
+"tosin.abasi" = "guitarist"
+# Output
+"tosin.abasi" : "guitarist"
+```
+
+#### Array of Tables
+
+At the moment only simple declarations like below are supported:
+
+```toml
+[[bin]]
+name = "deno"
+path = "cli/main.rs"
+
+[[bin]]
+name = "deno_core"
+path = "src/foo.rs"
+
+[[nib]]
+name = "node"
+path = "not_found"
+```
+
+will output:
+
+```json
+{
+  "bin": [
+    { "name": "deno", "path": "cli/main.rs" },
+    { "name": "deno_core", "path": "src/foo.rs" }
+  ],
+  "nib": [{ "name": "node", "path": "not_found" }]
+}
+```
+
+## Usage
+
+### Parse
+
+```ts
+import { parse } from "./parser.ts";
+import { readFileStrSync } from "../fs/read_file_str.ts";
+
+const tomlObject = parse(readFileStrSync("file.toml"));
+
+const tomlString = 'foo.bar = "Deno"';
+const tomlObject22 = parse(tomlString);
+```
+
+### Stringify
+
+```ts
+import { stringify } from "./parser.ts";
+const obj = {
+  bin: [
+    { name: "deno", path: "cli/main.rs" },
+    { name: "deno_core", path: "src/foo.rs" }
+  ],
+  nib: [{ name: "node", path: "not_found" }]
+};
+const tomlString = stringify(obj);
+```
