+=====Autosubmit database setup and install=====
+It is recommended to perform this kind of scalability analysis using a separate database different than the one from production experiments, in an isolated environment. The script creates a vast number of experiments in an automated way, so having them in the same database would be confusing for production users.
+To create an isolated environment and different database you have to follow next steps:
+- Create a new directory in any place you like (e.g. your $HOME dir):
+  mkdir ~/performance_autosubmit
+- Edit .autosubmitrc file (located by default in your $HOME dir), and change DATABASE, LOCAL and CONF paths to make them point to the directory created above. You need to replace any path pointing to /esnas/autosubmit by the path to the newly created directory.
+If the file is not present, you can create it and fill in with the contents below, but changing the user name with yours:
+  vi ~/.autosubmitrc
+  [database]
+  path = /home/Earth/xyepes/performance_autosubmit
+  filename = performance_autosubmit.db
+  [local]
+  path = /home/Earth/xyepes/performance_autosubmit
+  [conf]
+  jobs = /home/Earth/xyepes/performance_autosubmit/default
+  platforms = /home/Earth/xyepes/performance_autosubmit/default
+- Create default directory for the default configuration files that wiil be used for any new experiment of the scalability analysis:
+  mkdir ~/performance_autosubmit/default
+- Copy default jobs.conf and platforms.conf files from /esnas/autosubmit/default, or any other experiment you'd like, to the newly created directory:
+  cp /esnas/autosubmit/a0mo/conf/platforms_a0mo.conf ~/performance_autosubmit/default/platforms.conf
+  cp /esnas/autosubmit/a0mo/conf/jobs_a0mo.conf ~/performance_autosubmit/default/jobs.conf
+- Execute autosubmit install command
+  autosubmit install
+Then it is ready to be used.
