+   yarn add <other dependencies>
+   ```
+
+3. Consuming from the sample client
+
+   This process should definitely be reworked for a better dev experience. Currently there are a lot of manual steps.
+
+   Build the project using the instructions below:
+
+   ```
+   yarn build
+   yarn build:types
+   ```
+
+   The yarn build:types is to create the index.d.ts, which is used for type checking throughout the project. While during startup, it may not error out, there
+   can be issues during runtime. It is to ensure that the types of everything used in the project are consistent.
+
+   Copy each file from the dist folder after the build. You will have:
+
+   cms-bluebutton-sdk.cjs.js
+   cms-bluebutton-sdk.esm.js
+   cms-bluebutton-sdk.umd.js
+   index.d.ts
+
+   The three files are used so that the sdk can be used in a variety of projects, such as a module or in a browser.
+
+   In the sample-client, you will then create a folder within the server folder location. Name the folder something like node-sdk.
+   Copy the entire contents of the dist folder into the newly created node-sdk folder.
+   Put the .js files into a new dist folder within the node-sdk folder.
+   Back in this repo (cms-bb2-node-sdk) copy the package.json into the sample client's node-sdk folder.
+   This entire process is to allow the sdk to be locally referenced while inside the Docker container. Ideally, there would be a more elegant way to do this.
+
+   The folder structure will look like this:
 
-    ```
-    mkdir my_proj
-    cd my_proj
-    yarn init
-    yarn add <path to local cms-bluebutton-sdk local repository base directory>
+   ```
+    server
+    └───node-sdk
+    │   │   index.d.ts
+    │   │   package.json (THIS IS THE ONE FROM THIS SDK REPO)
+    │   └───dist
+    │       │   cms-bluebutton-sdk.umd.js
+    │       │   ms-bluebutton-sdk.esm.js
+    │       │   cms-bluebutton-sdk.cjs.js
+   ```
 
-    continue adding other dependencies, e.g. express, ts-node, etc., ...
+   Within the sample client in the server folder, there is another package.json (Note: NOT the one in node-sdk) This package.json will have
 
-    yarn add express @types/express ts-node
-    yarn add <other dependencies>
-    ```
+   "cms-bluebutton-sdk": "^{version}",
 
+   Replace the version with "file:node-sdk" to use the locally created node-sdk folder from previous steps. This will allow you to see changes to this repo.
