 The `flipt-client-node` directory contains the TypeScript source code for a Flipt evaluation client.
 
-## Instructions
+## Installation
 
-To use this client, you can run the following command from the root of the repository:
+Currently, to use this client, you'll need to build the dynamic library and the Node package locally and install it. This is a temporary solution until we can figure out a better way to package and distribute the libraries.
 
-```bash
-cargo build --release
-```
+The dynamic library will contain the functionality necessary for the client to make calls to the Flipt engine via FFI. See [flipt-engine](../flipt-engine) for more information on the Flipt engine and FFI.
+
+### Prerequisites
+
+- [Rust](https://www.rust-lang.org/tools/install)
+- [Node](https://nodejs.org/en/download/)
+- [Make](https://www.gnu.org/software/make/)
+
+### Automated Build
+
+1. Build and copy the dynamic library to the `flipt-client-node` directory. You can do this by running the following command from the root of the repository:
+
+    ```bash
+
+    ```bash
+    make node
+    ```
+
+2. Install the package locally. You can do this by running the following command from the `flipt-client-node` directory:
 
-This should generate a `target/` directory in the root of this repository, which contains the dynamic linking library built for your platform. This dynamic library will contain the functionality necessary for the Node client to make FFI calls. You'll need to set the `FLIPT_ENGINE_LIB_PATH` environment variable depending on your platform::
+    ```bash
+    npm install -g flipt-client-node-{version}.tgz
+    ```
+
+### Manual Build
+
+1. Build the Rust dynamic library
+
+    ```bash
+    cargo build --release
+    ```
+
+This should generate a `target/` directory in the root of this repository, which contains the dynamically linked library built for your platform.
+
+2. You'll need to copy the dynamic library to the `flipt-client-node/ext` directory. This is a temporary solution until we can figure out a better way to package the libraries with the package.
 
 The `path/to/lib` will be the path to the dynamic library which will have the following paths depending on your platform.
 
 - **Linux**: `{REPO_ROOT}/target/release/libfliptengine.so`
 - **Windows**: `{REPO_ROOT}/target/release/libfliptengine.dll`
 - **MacOS**: `{REPO_ROOT}/target/release/libfliptengine.dylib`

+# namespace is the first positional argument and is optional here and will have a value of "default" if not specified.
+# opts is the second positional argument and is also optional, the structure is:
+# {
+#   "url": "http://localhost:8080",
+#   "update_interval": 120,
+#   "auth_token": "secret"
+# }
+# 
+# You can replace the url with where your upstream Flipt instance points to, the update interval for how long you are willing
+# to wait for updated flag state, and the auth token if your Flipt instance requires it.
+client = Flipt::EvaluationClient.new()
 resp = client.evaluate_variant({ flag_key: 'buzz', entity_id: 'someentity', context: { fizz: 'buzz' } })
 
 puts resp
