 # About
 
-<!-- TODO: write document
-
-  This document contains a short introduction to the language.
-
-  The introduction should be relatively brief and touch upon what
-  makes the language interesting (and possibly unique). The goal
-  is to help students decide if they want to join this track.
-
-  The contents of this document are displayed on the track page,
-  provided the student has not joined the track.
-
-  See https://exercism.org/docs/building/tracks/docs for more information. -->
+If it compiles, it runs.
+ReScript is a typed language that brings OCaml's type system to the JavaScript ecosystem, with built-in JSX syntax and official React bindings.
+Every type is inferred, there is no `any` escape hatch, and pattern matching is exhaustive.

 # Installation
 
-<!-- TODO: write document
+This track uses ReScript 12 and relies on [Node.js][nodejs] 22 or greater.
+Many systems will have this pre-installed or you may have previously installed it for another track.
 
-  This document should describe what the student needs to install
-  to allow working on the track on their local system using the CLI.
+Open a terminal and run:
 
-  You can include the installation instructions in this document, but
-  usually it is better to link to a resource with the official installation
-  instructions, to prevent the instructions from becoming outdated.
+```sh
+node -v
+```
 
-  The contents of this document are displayed on the track's documentation
-  page at `https://exercism.org/docs/tracks/<track>/installation`.
+If Node isn't installed or an older version is listed, please follow [the official Node.js installation][nodejs-install] instructions for your platform.
 
-  See https://exercism.org/docs/building/tracks/docs for more information. -->
+## Installing dependencies
+
+Each ReScript exercise is a self-contained npm project.
+After downloading an exercise with the [Exercism CLI][exercism-cli], install the project dependencies including ReScript and you're ready to go:
+
+```sh
+cd /path/to/exercise
+npm install
+```
+
+## Editor support
+
+The ReScript Project maintains a [list of both official and community-supported editor plugins][rescript-plugins].

+[nodejs-install]: https://nodejs.org/en/download

 # Learning
 
-<!-- TODO: write document
+## Official documentation
 
-  This document should link to learning resources.
+- [ReScript Language Manual](https://rescript-lang.org/docs/manual/latest/overview) — primary reference
+- [ReScript API](https://rescript-lang.org/docs/manual/latest/api) — standard library reference
+- [ReScript Playground](https://rescript-lang.org/try) — in-browser editor where you can write ReScript and see the compiled JavaScript output side by side.

-  The contents of this document are displayed on the track's documentation
-  page at `https://exercism.org/docs/tracks/<track>/learning`.
+If you know **JavaScript or TypeScript**, ReScript's syntax will look familiar.

-# Tests
+# Running the Tests
 
-<!-- TODO: write document
+## Download an Exercise
 
-  This document should describe everything related to running tests in the track.
+Use the [Exercism CLI][cli] to download the exercise you want to work on.
 
-  If your track uses skipped tests, this document can explain why thet is used and
-  how to unskip tests.
+```sh
+exercism download --track=rescript --exercise=hello-world
+```
 
-  This document can also link to the testing framework documentation.
+Then change into the exercise directory.
 
-  The contents of this document are displayed on the track's documentation
-  page at `https://exercism.org/docs/tracks/<track>/tests`.
+```sh
+cd /path/to/exercism/rescript/hello-world
+```
 
-  See https://exercism.org/docs/building/tracks/docs for more information. -->
+## Install Dependencies
+
+Before running the tests, install the exercise dependencies.
+
+```sh
+npm install
+```
+
+## Run the Tests
+
+Compile and run the provided test suite using either `exercism test` or `npm install`.
+
+## Understanding Test Results
+
+The test runner shows each test run with a pass/fail status.
+
+```text
+1/3: no name given
+  PASS - no name given
+2/3: a name given
+  FAIL - a name given
+    ---
+    operator: equal
+    left:  One for you, one for me.
+    right: One for Alice, one for me.
+    ...
+3/3: another name given
+  FAIL - another name given
+    ---
+    operator: equal
+    left:  One for you, one for me.
+    right: One for Bob, one for me.
+    ...
+
+# Ran 3 tests (3 assertions)
+# 1 passed
+# 2 failed
+```
+
+`left` is what your code returned. `right` is what the test expected.
+
+## Understanding the Exercise Structure
+
+```text
+two-fer/
+├── src/
+│   ├── TwoFer.res   // your solution goes here
+│   └── TwoFer.resi  // the optional interface file containing signatures
+├── tests/
+│   └── TwoFer_test.res // your test suite
+├── package.json // used to install project dependencies
+└── ...
+```
+
+`TwoFer.resi` here is an optional interface file.
+When present, it defines the function signatures your solution must satisfy and can serve as a hint for what to implement.
+
+For example, if the interface declares:
+
+```rescript
+let hello: unit => string
+```
+
+Your implementation should define:
+
+```rescript
+let hello = () => "Hello, World!"
+```
+
+## Compiler Errors
+
+If your code doesn't compile, ReScript's compiler produces detailed error messages with the exact location and expected types.
+
+```text
+  We've found a bug for you!
+
+  1 │ let x: string = 42
+
+  This has type: int
+  But it's expected to have type: string
+
+  You can convert int to string with Int.toString.
+```
+
+Read the error message carefully because it usually points directly to the problem.

 # Help
 
-<!-- TODO: write document
+## Useful resources
 
-  This document should contain track-specific instructions on how to get help when
-  the student is stuck.
-
-  The instructions should be short and to the point.
-
-  You could link to resources like Gitter channels, forums or mailing lists:
-  whatever can help a student become unstuck.
-
-  This document should **not** link to Exercism-wide (track-agnostic) help resources,
-  as those resources will automatically be included in the HELP.md file.
-
-  The links in this document can overlap with those in docs/LEARNING.md or docs/RESOURCES.md
-
-  When a student downloads an exercise via the CLI, this file's contents are
-  included into the HELP.md file.
