+
+First download the cockroachdb tarball from https://binaries.cockroachdb.com or search for it in the website: https://www.cockroachlabs.com
+
+```
+$ git clone https://github.com/tomogoma/cockroach-installer
+$ cd roach-installer
+$ ./systemdInstaller.sh /path/to/downloaded/cockroach-tarbal.tz
+```
+
+
+## Install outcome ##
+
+
+Start
+
+`$ systemctl start cockroach.service`
+
+Stop
+
+`$ systemctl stop cockroach.service`
+
+Check status
+
+`$ systemctl status cockroach.service`
+
+
+Install Directories
+
+The cockroach db binary is installed into
+`/usr/local/cockroachdb`
+
+The db certs are located at
+`/usr/local/cockroachdb/certs`
+
+The data dir is located at
+`/var/data/cockroachdb`
+
+A systemd service unit file is created at
+`/etc/systemd/system/cockroach.service`
+
+## Uninstall ##
+
+`$ cd /path/to/roach-installer`
+
+`$ ./systemdUninstaller.sh`
+
+
+## Configure a dependent systemd service ##
+
+If your service depends on cockroach db, in the service’s unit file add the following lines:
+
+
+```
+[Unit]
+
+...
+
+After=cockroach.service
+
+Requires=cockroach.service
+
+...
+```
+
+
+## Get your app’s postgresql driver url ##
+
+1. Start the cockroachdb service as described in Install Outcome
+1. Check the status of the service as described in Install Outcome
+1. Copy the url you see under the sql flag: e.g:
+
+ `sql: postgresql://[email protected]:26257?sslcert=%2FUsers%2F…`
+
+ Will yield the url:
+
+ `postgresql://[email protected]:26257?sslcert=%2FUsers%2F…`
