+#
+# Installing the Required Software
+# ================================
+#
+# These instructions expect that you have a freshly installed Ubuntu 18.04.
+#
+# Make sure all packages are are up-to-date by running:
+#
+
+#DOCS:    :::sh
+    sudo apt-get -o DPkg::options::="--force-confdef" -o DPkg::options::="--force-confold" --force-yes -fuy install grub-pc #DOCS:
+    sudo apt-get update -qq
+
+# Now you can install all packages needed for Nominatim:
+
+    sudo apt-get install -y build-essential cmake g++ libboost-dev libboost-system-dev \
+                            libboost-filesystem-dev libexpat1-dev zlib1g-dev libxml2-dev\
+                            libbz2-dev libpq-dev libproj-dev \
+                            postgresql-server-dev-10 postgresql-10-postgis-2.4 \
+                            postgresql-contrib-10 \

+                            php-intl git
+
+# If you want to run the test suite, you need to install the following
+# additional packages:
+
+    sudo apt-get install -y python3-setuptools python3-dev python3-pip \
+                            python3-psycopg2 python3-tidylib phpunit php-cgi
+
+    pip3 install --user behave nose
+    sudo pear install PHP_CodeSniffer
+
+#
+# System Configuration
+# ====================
+#
+# The following steps are meant to configure a fresh Ubuntu installation
+# for use with Nominatim. You may skip some of the steps if you have your
+# OS already configured.
+#
+# Creating Dedicated User Accounts
+# --------------------------------
+#
+# Nominatim will run as a global service on your machine. It is therefore
+# best to install it under its own separate user account. In the following
+# we assume this user is called nominatim and the installation will be in
+# /srv/nominatim. To create the user and directory run:
+#
+#     sudo useradd -d /srv/nominatim -s /bin/bash -m nominatim
+#
+# You may find a more suitable location if you wish.
+#
+# To be able to copy and paste instructions from this manual, export
+# user name and home directory now like this:
+#
+    export USERNAME=vagrant        #DOCS:    export USERNAME=nominatim
+    export USERHOME=/home/vagrant  #DOCS:    export USERHOME=/srv/nominatim
+#
+# **Never, ever run the installation as a root user.** You have been warned.
+#
+# Make sure that system servers can read from the home directory:
+
+    chmod a+x $USERHOME
+
+# Setting up PostgreSQL
+# ---------------------
+#
+# Tune the postgresql configuration, which is located in 
+# `/etc/postgresql/9.5/main/postgresql.conf`. See section *Postgres Tuning* in
+# [the installation page](../admin/Installation.md#postgresql-tuning)
+# for the parameters to change.
+#
+# Restart the postgresql service after updating this config file.
+
+    sudo systemctl restart postgresql
+
+#
+# Finally, we need to add two postgres users: one for the user that does
+# the import and another for the webserver which should access the database
+# for reading only:
+#
+
+    sudo -u postgres createuser -s $USERNAME
+    sudo -u postgres createuser www-data
+
+#
+# Setting up the Apache Webserver
+# -------------------------------
+#
+# You need to create an alias to the website directory in your apache
+# configuration. Add a separate nominatim configuration to your webserver:
+
+#DOCS:```sh
+sudo tee /etc/apache2/conf-available/nominatim.conf << EOFAPACHECONF
+<Directory "$USERHOME/build/website"> #DOCS:<Directory "$USERHOME/Nominatim/build/website">
+  Options FollowSymLinks MultiViews
+  AddType text/html   .php
+  DirectoryIndex search.php
+  Require all granted
+</Directory>
+
+Alias /nominatim $USERHOME/build/website  #DOCS:Alias /nominatim $USERHOME/Nominatim/build/website
+EOFAPACHECONF
+#DOCS:```
+
+sudo sed -i 's:#.*::' /etc/apache2/conf-available/nominatim.conf #DOCS:
+
+#
+# Then enable the configuration and restart apache
+#
+
+    sudo a2enconf nominatim
+    sudo systemctl restart apache2
+
+#
+# Installing Nominatim
+# ====================
+#
+# Building and Configuration
+# --------------------------
+#
+# Get the source code from Github and change into the source directory
+#
+if [ "x$1" == "xyes" ]; then  #DOCS:    :::sh
+    cd $USERHOME
+    git clone --recursive git://github.com/openstreetmap/Nominatim.git
+    cd Nominatim
+else                               #DOCS:
+    cd $USERHOME/Nominatim         #DOCS:
+fi                                 #DOCS:
+
+# When installing the latest source from github, you also need to
+# download the country grid:
+
+if [ ! -f data/country_osm_grid.sql.gz ]; then       #DOCS:    :::sh
+    wget -O data/country_osm_grid.sql.gz https://www.nominatim.org/data/country_grid.sql.gz
+fi                                 #DOCS:
+
+# The code must be built in a separate directory. Create this directory,
+# then configure and build Nominatim in there:
+
+    cd $USERHOME                   #DOCS:    :::sh
+    mkdir build
+    cd build
+    cmake $USERHOME/Nominatim
+    make
+
+# You need to create a minimal configuration file that tells nominatim
+# where it is located on the webserver:
+
+#DOCS:```sh
+tee settings/local.php << EOF
+<?php
+ @define('CONST_Website_BaseURL', '/nominatim/');
+EOF
+#DOCS:```
+
+
+# Nominatim is now ready to use. Continue with
+# [importing a database from OSM data](../admin/Import-and-Update.md).
