 A quick setup guide for both the environments can be found below. For more details, check out the [Frappe/ERPNext Docker Repository](https://github.com/frappe/frappe_docker).
 
-### Easy Install Script
-
-The Easy Install script should get you going with a Frappe/ERPNext setup with minimal manual intervention and effort. Since there are a lot of configurations being automatically setup, we recommend executing this script on a fresh server.
-
-**Note:** This script works only on GNU/Linux based server distributions, and has been designed and tested to work on Ubuntu 16.04+, CentOS 7+, and Debian-based systems.
-
-> This script installs Version 12 by default. It is untested with Version 13 and above. Containerized or manual installs are recommended for newer setups.
-
-#### Prerequisites
-
-You need to install the following packages for the script to run:
-
- - ##### Ubuntu and Debian-based Distributions:
-
-	```sh
-	$ apt install python3-minimal build-essential python3-setuptools
-	```
-
- - ##### CentOS and other RPM Distributions:
-
-	```sh
-	$ dnf groupinstall "Development Tools"
-	$ dnf install python3
-	```
-
-#### Setup
-
-Download the Easy Install script and execute it:
-
-```sh
-$ wget https://raw.githubusercontent.com/frappe/bench/develop/install.py
-$ python3 install.py --production
-```
-
-The script should then prompt you for the MySQL root password and an Administrator password for the Frappe/ERPNext instance, which will then be saved under `$HOME/passwords.txt` of the user used to setup the instance. This script will then install the required stack, setup bench and a default ERPNext instance.
-
-When the setup is complete, you will be able to access the system at `http://<your-server-ip>`, wherein you can use the administrator password to login.
-
-#### Troubleshooting
-
-In case the setup fails, the log file is saved under `/tmp/logs/install_bench.log`. You may then:
-
- - Create an Issue in this repository with the log file attached.
- - Search for an existing issue or post the log file on the [Frappe/ERPNext Discuss Forum](https://discuss.erpnext.com/c/bench) with the tag `installation_problem` under "Install/Update" category.

-# Easy Install Script
-
-- This script will install the pre-requisites, install bench and setup an ERPNext site `(site1.local under frappe-bench)`
-- Passwords for Frappe Administrator and MariaDB (root) will be asked and saved under `~/passwords.txt`
-- MariaDB (root) password may be `password` on a fresh server
-- You can then login as **Administrator** with the Administrator password
-- The log file is saved under `/tmp/logs/install_bench.log` in case you run into any issues during the install.
-- If you find any problems, post them on the forum: [https://discuss.erpnext.com](https://discuss.erpnext.com/tags/installation_problem) under the "Install / Update" category.
-
----
-
-## What will this script do?
-
-- Install all the pre-requisites
-- Install the command line `bench` (under ~/.bench)
-- Create a new bench (a folder that will contain your entire frappe/erpnext setup at ~/frappe-bench)
-- Create a new ERPNext site on the bench (site1.local)
-
----
-
-## Getting started with easy install...
-
-Open your Terminal and enter:
-
-#### 0. Setup user & Download the install script
-
-If you are on a fresh server and logged in as root, at first create a dedicated user for frappe
-& equip this user with sudo privileges
-
-```
-  adduser [frappe-user]
-  usermod -aG sudo [frappe-user]
-```
-
-*(it is very common to use "frappe" as frappe-username, but this comes with the security flaw of ["frappe" ranking very high](https://www.reddit.com/r/dataisbeautiful/comments/b3sirt/i_deployed_over_a_dozen_cyber_honeypots_all_over/?st=JTJ0SC0Q&sh=76e05240) in as a username challenged in hacking attempts. So, for production sites it is highly recommended to use a custom username harder to guess)*
-
-*(you can specify the flag --home to specify a directory for your [frappe-user]. Bench will follow the home directory specified by the user's home directory e.g. /data/[frappe-user]/frappe-bench)*
-
-Switch to `[frappe-user]` (using `su [frappe-user]`) and start the setup
-
-	wget https://raw.githubusercontent.com/frappe/bench/develop/install.py
-
-
-#### 1. Run the install script
-
-	sudo python3 install.py
-
-*Note: `user` flag to create a user and install using that user (By default, the script will create a user with the username `frappe` if the --user flag is not used)*
-
-For production or development, append the `--production` or `--develop` flag to the command respectively.
-
-	sudo python3 install.py --production --user [frappe-user]
-
-or
-
-	sudo python3 install.py --develop
-	sudo python3 install.py --develop --user [frappe-user]
-
-	sudo python3 install.py --production --user [frappe-user] --container
-
-*Note: `container` flag to install inside a container (this will prevent the `/proc/sys/vm/swappiness: Read-only` file system error)*
-
-
-	python3 install.py --production --version 11 --user [frappe-user]
-
-use --version flag to install specific version
-
-	python3 install.py --production --version 11 --python python2.7 --user [frappe-user]
-
-use --python flag to specify virtual environments python version, by default script setup python3
-
----
-
-## How do I start ERPNext
-
-1. For development: Go to your bench folder (`~[frappe-user]/frappe-bench` by default) and start the bench with `bench start`
-2. For production: Your process will be setup and managed by `nginx` and `supervisor`. Checkout [Setup Production](https://frappe.io/docs/user/en/bench/guides/setup-production.html) for more information.
-
----
-
-## An error occured mid installation?
-
-TLDR; Save the logs!
-
-1. The easy install script starts multiple processes to install prerequisites, system dependencies, requirements, sets up locales, configuration files, etc.
-
-2. The script pipes all these process outputs and saves it under `/tmp/log/{easy-install-filename}.log` as prompted by the script in the beginning of the script or/and if something went wrong again.
-
-3. Retain this log file and share it in case you need help with proceeding with the install. Since, the file's saved under `/tmp` it'll be cleared by the system after a reboot. Be careful to save it elsewhere if needed!
-
-3. A lot of things can go wrong in setting up the environment due to prior settings, company protocols or even breaking changes in system packages and their dependencies.
-
-4. Sharing your logfile in any issues opened related to this can help us find solutions to it faster and make the script better!
