 # DataHub Quickstart Guide
 
-1. Install [docker](https://docs.docker.com/install/) and [docker-compose](https://docs.docker.com/compose/install/) (if using Linux). Make sure to allocate enough hardware resources for Docker engine. Tested & confirmed config: 2 CPUs, 8GB RAM, 2GB Swap area.
-2. Open Docker either from the command line or the desktop app and ensure it is up and running.
-3. Clone this repo and `cd` into the root directory of the cloned repository.
-4. Run the following command to download and run all Docker containers locally:
-    ```
-    ./docker/quickstart.sh
-    ```
-    This step takes a while to run the first time, and it may be difficult to tell if DataHub is fully up and running from the combined log. Please use [this guide](debugging.md#how-can-i-confirm-if-all-docker-containers-are-running-as-expected-after-a-quickstart) to verify that each container is running correctly.
-5. At this point, you should be able to start DataHub by opening [http://localhost:9002](http://localhost:9002) in your browser. You can sign in using `datahub` as  username and any password (no password validation by default). However, you'll notice that no data has been ingested yet.
-6. To ingest provided [sample data](https://github.com/linkedin/datahub/blob/master/metadata-ingestion/mce-cli/bootstrap_mce.dat) to DataHub, switch to a new terminal window, `cd` into the cloned `datahub` repo, and run the following command:
-    ```
-    ./docker/ingestion/ingestion.sh
-    ```
-   After running this, you should be able to see and search sample datasets in DataHub.
-7. That's it! To get some real data into DataHub, take a look at the [ingestion framework](../metadata-ingestion/README.md).
+## Deploying DataHub
 
-Please refer to the [debugging guide](debugging.md) if you encounter any issues during the quickstart.
+To deploy a new instance of DataHub, perform the following steps.  
+
+1. Install [docker](https://docs.docker.com/install/) and [docker-compose](https://docs.docker.com/compose/install/) (if using Linux). Make sure to allocate enough hardware resources for Docker engine. Tested & confirmed config: 2 CPUs, 8GB RAM, 2GB Swap area.
+
+
+2. Launch the Docker Engine from command line or the desktop app. 
+
+
+3. Install the DataHub CLI
+   
+   a. Ensure you have Python 3.6+ installed & configured. (Check using `python3 --version`)
+   
+   b. Run the following commands in your terminal 
+   ```
+   python3 -m pip install --upgrade pip wheel setuptools
+   python3 -m pip uninstall datahub acryl-datahub || true  # sanity check - ok if it fails
+   python3 -m pip install --upgrade acryl-datahub
+   datahub version
+   ```
+   If you see "command not found", try running cli commands with the prefix 'python3 -m' instead: `python3 -m datahub version`
+
+
+4. To deploy DataHub, run the following CLI command from your terminal
+   ```
+   datahub docker quickstart 
+   ```
+   Upon completion of this step, you should be able to navigate to the DataHub UI at [http://localhost:9002](http://localhost:9002) in your browser. You can sign in using `datahub` as  username and any password (no password validation by default).
+
+
+5. To ingest the sample metadata, run the following CLI command from your terminal
+   ```
+   datahub docker ingest-sample-data
+   ```
+   
+That's it! To start pushing your company's metadata into DataHub, take a look at the [Metadata Ingestion Framework](../metadata-ingestion/README.md).
+
+
+## Resetting DataHub
+
+To cleanse DataHub of all of it's state (e.g. before ingesting your own), you can use the CLI `nuke` command. 
+
+```
+datahub docker nuke
+```
+
+
+## FAQ
+
+### Command not found: datahub
+
+If running the datahub cli produces "command not found" errors inside your terminal, your system may be defaulting to an older 
+version of Python. Try prefixing your `datahub` commands with `python3 -m`:
+```
+python3 -m datahub docker quickstart
+```
