+Installation
+---
+
+After installing the dependencies, clone the repository using git, e.g.
+
+```
+git clone https://git.finalrewind.org/db-fakedisplay
+```
+
+Make sure that all files (including `.git`, which is used to determine the
+software version) are readable by your www user, and follow the steps in the
+next sections.
+
+Perl Dependencies
+---
+
+db-infoscreen depends on a set of Perl modules which are documented in
+`cpanfile`. After installing the dependencies mentioned above, you can use
+carton or cpanminus to install Perl depenencies locally.
+
+In the project root directory (where `cpanfile` resides), run either
+
+```
+carton install
+```
+
+or
+
+```
+cpanm --installdeps .
+```
+
+and set `PERL5LIB=.../local/lib/perl5` before running index.pl or wrap it
+with `carton exec hypnotoad index.pl`.

db-infoscreen typically needs 50MB RAM per worker process, though calculating
with 100MB per worker is recommended to leave a safety margin.
