+
+#
+# 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:
+#
+if [ "x$USERNAME" == "x" ]; then #DOCS:
+    export USERNAME=vagrant        #DOCS:    export USERNAME=nominatim
+    export USERHOME=/home/vagrant  #DOCS:    export USERHOME=/srv/nominatim
+fi                                 #DOCS:
+#
+# **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 $USERHOME
+
+# Setting up PostgreSQL
+# ---------------------
+#
+# Tune the postgresql configuration, which is located in 
+# `/etc/postgresql/14/main/postgresql.conf`. See section *Postgres Tuning* in
+# [the installation page](../admin/Installation.md#postgresql-tuning)
+# for the parameters to change.
+#
+# Restart the postgresql service after updating this config file.
+
+if [ "x$NOSYSTEMD" == "xyes" ]; then  #DOCS:
+    sudo pg_ctlcluster 14 main start  #DOCS:
+else                                  #DOCS:
+    sudo systemctl restart postgresql
+fi                                    #DOCS:
+#
+# 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
+
+#
+# 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 https://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:
+
+    mkdir $USERHOME/build
+    cd $USERHOME/build
+    cmake $USERHOME/Nominatim
+    make
+    sudo make install
+
+# Nominatim is now ready to use. You can continue with
+# [importing a database from OSM data](../admin/Import.md). If you want to set up
+# a webserver first, continue reading.
+#
+# Setting up a webserver
+# ======================
+#
+# The webserver should serve the php scripts from the website directory of your
+# [project directory](../admin/Import.md#creating-the-project-directory).
+# This directory needs to exist when being configured.
+# Therefore set up a project directory and create a website directory:
+
+    mkdir $USERHOME/nominatim-project
+    mkdir $USERHOME/nominatim-project/website
+
+# The import process will populate the directory later.
+
+#
+# Option 1: Using Apache
+# ----------------------
+#
+if [ "x$2" == "xinstall-apache" ]; then #DOCS:
+#
+# Apache has a PHP module that can be used to serve Nominatim. To install them
+# run:
+
+    sudo apt install -y apache2 libapache2-mod-php
+
+# You need to create an alias to the website directory in your apache
+# configuration. Add a separate nominatim configuration to your webserver:
+
+#DOCS:```sh
+sudo tee /etc/apache2/conf-available/nominatim.conf << EOFAPACHECONF
+<Directory "$USERHOME/nominatim-project/website">
+  Options FollowSymLinks MultiViews
+  AddType text/html   .php
+  DirectoryIndex search.php
+  Require all granted
+</Directory>
+
+Alias /nominatim $USERHOME/nominatim-project/website
+EOFAPACHECONF
+#DOCS:```
+
+#
+# Then enable the configuration and restart apache
+#
+
+    sudo a2enconf nominatim
+if [ "x$NOSYSTEMD" == "xyes" ]; then  #DOCS:
+    sudo apache2ctl start             #DOCS:
+else                                  #DOCS:

+
+# The Nominatim API is now available at `http://localhost/nominatim/`.
+
+fi   #DOCS:
+
+#
+# Option 2: Using nginx
+# ---------------------
+#
+if [ "x$2" == "xinstall-nginx" ]; then #DOCS:
+
+# Nginx has no native support for php scripts. You need to set up php-fpm for
+# this purpose. First install nginx and php-fpm:

+# You need to configure php-fpm to listen on a Unix socket.
+
+#DOCS:```sh
+sudo tee /etc/php/8.1/fpm/pool.d/www.conf << EOF_PHP_FPM_CONF
