+# Quickstart
+
+## Server
+
+Starting the Utapi server can be done in two ways:
+[using NPM](#using-npm-2-minutes) or
+[using Docker](#using-docker-5-minutes). Either method will start a server
+locally, listening on port 8100.
+
+### Using NPM (~2 minutes)
+
+Please use node v10.16.0 (npm v6.9.0).
+
+1. Install dependencies:
+
+    ```
+    npm install
+    ```
+
+2. Start the server:
+
+    ```
+    $ npm start
+    utapi@8.0.0 start /Users/repos/scality/utapi
+    node start-server.js
+    {"name":"Utapi","time":1562008743439,"id":0,"childPid":55156,"level":"info",
+    "message":"Worker started","hostname":"MacBook-Pro-2.local", "pid":55155}
+    ...
+    ```
+
+### Using Docker (~5 minutes)
+
+1. Build the image:
+
+    ```
+    $ docker build --tag utapi .
+    Sending build context to Docker daemon  10.79MB
+    Step 1/7 : FROM node:10-slim
+    ---> bce75035da07
+    ...
+    Successfully built 5699ea8e7dec
+    ```
+
+2. Run the image:
+
+    ```
+    $ docker run --publish 8100:8100 --detach utapi
+    25fea1a990b18e7f1f6c76cc5d0c5d564fd6bffb87e1acf5f724db16d602a5b5
