 # Installation
 
 ## Bootstrap a default version of Amundsen using Docker
-The following instructions are for setting up a version of Amundsen using Docker. At the moment, we only support a bootstrap for connecting the Amundsen application to an example metadata service.
+The following instructions are for setting up a version of Amundsen using Docker.
 
-1. Install `docker`, `docker-compose`, and `docker-machine`.
-2. Install `virtualbox` and `virtualenv`.
-3. Start a managed docker virtual host using the following command:
-```bash
-# in our examples our machine is named 'default'
-$ docker-machine create -d virtualbox default
-```
-4. Check your docker daemon locally using:
-```bash
-$ docker-machine ls
-```
-  You should see the `default` machine listed, running on virtualbox with no errors listed.
-5. Set up the docker environment using
-```bash
-$ eval $(docker-machine env default)
-```
-TODO (ttannis): Once submodules configured, they _should_ be able to `cd amundsenfrontendlibrary`, etc. Will go through setup again and verify it works.
-6. Setup your local environment.
-  * Clone [amundsenfrontendlibrary](https://github.com/lyft/amundsenfrontendlibrary), [amundsenmetadatalibrary](https://github.com/lyft/amundsenmetadatalibrary), and [amundsensearchlibrary](https://github.com/lyft/amundsensearchlibrary).
-  * In your local versions of each library, update the `LOCAL_HOST` in the `LocalConfig` with the IP used for the `default` docker machine. You can see the IP in the `URL` outputted from running `docker-machine ls`.
-7. Start all of the services using:
-```bash
-# in ~/<your-path-to-cloned-repo>/amundsen
-$ docker-compose -f docker-amundsen.yml up
-```
-8. Ingest dummy data into Neo4j by doing the following:
+1. Install `docker` and  `docker-compose`.
+2. Clone [amundsenfrontendlibrary](https://github.com/lyft/amundsenfrontendlibrary) or download the [docker-amundsen.yml](https://github.com/lyft/amundsenfrontendlibrary/blob/master/docker-amundsen.yml) file directly.
+3. Enter the directory where the `docker-amundsen.yml` file is and then:
+    ```bash
+    $ docker-compose -f docker-amundsen.yml up
+    ```
+4. Ingest dummy data into Neo4j by doing the following:
    * Clone [amundsendatabuilder](https://github.com/lyft/amundsendatabuilder).
-  * Update the `NEO4J_ENDPOINT` and `Elasticsearch host` in [sample_data_loader.py](https://github.com/lyft/amundsendatabuilder/blob/master/example/scripts/sample_data_loader.py) and replace `localhost` with the IP used for the `default` docker machine. You can see the IP in the `URL` outputted from running `docker-machine ls`.
-  * Run the following commands:
+   * Run the following commands in the `amundsenddatabuilder` directory:
    ```bash
-    # in ~/<your-path-to-cloned-repo>/amundsendatabuilder
-    $ virtualenv -p python3 venv3
-    $ source venv3/bin/activate  
+    $ python3 -m venv venv
+    $ source venv/bin/activate  
     $ pip3 install -r requirements.txt
-    $ python setup.py install      
-    $ python example/scripts/sample_data_loader.py
+    $ python3 setup.py install
+    $ python3 example/scripts/sample_data_loader.py
    ```
-9. Verify dummy data has been ingested by viewing in Neo4j by visiting `http://YOUR-DOCKER-HOST-IP:7474/browser/` and run `MATCH (n:Table) RETURN n LIMIT 25` in the query box. You should see two tables -- `hive.test_schema.test_table1` and `dynamo.test_schema.test_table2`.
-10. View UI at `http://YOUR-DOCKER-HOST-IP:5000/table_detail/gold/hive/test_schema/test_table1` or `/table_detail/gold/dynamo/test_schema/test_table2`
-11. View UI at `http://YOUR-DOCKER-HOST-IP:5000` and try to search `test`, it should return some result.
+5. View UI at [`http://localhost:5000`](http://localhost:5000) and try to search `test`, it should return some result.
+
+### Verify setup
+
+1. You can verify dummy data has been ingested into Neo4j by by visiting [`http://localhost:7474/browser/`](http://localhost:7474/browser/) and run `MATCH (n:Table) RETURN n LIMIT 25` in the query box. You should see two tables:
+   1. `hive.test_schema.test_table1`
+   2. `dynamo.test_schema.test_table2`
+2. You can verify the data has been loaded into the metadataservice by visiting:
+   1. [`http://localhost:5000/table_detail/gold/hive/test_schema/test_table1`](http://localhost:5000/table_detail/gold/hive/test_schema/test_table1)
+   2. [`http://localhost:5000/table_detail/gold/dynamo/test_schema/test_table2`](http://localhost:5000/table_detail/gold/dynamo/test_schema/test_table2)
+
+### Troubleshooting
+
+1. If the docker container doesn't have enough heap memory for Elastic Search, `es_amundsen` will fail during `docker-compose`.
+   1. docker-compose error: `es_amundsen | [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]`
+   2. Increase the heap memory [detailed instructions here](https://www.elastic.co/guide/en/elasticsearch/reference/7.1/docker.html#docker-cli-run-prod-mode)
+      1. Edit `/etc/sysctl.conf`
+      2. Make entry `vm.max_map_count=262144`. Save and exit.
+      3. Reload settings `$ sysctl -p`
+      4. Restart `docker-compose`
