+# Development
+
+## Directories
+
+Projects being analysed by the DSpot Web UI are cloned and analysed in a dedicated directory, configured in section `work_dir` of the main configuration file of the application: `d_spot_web.conf`.
+
+In this directory each directory is a project, with all required files and information for the project stored inside. A typical architecture looks as follows:
+
+* `work_dir`
+  - `project_a`
+    - `src` is the git extract (clone) of the repository.
+    - `output` is the hierarchy generated during the dspot execution.
+    - `results.zip` is the compressed file of the results.
+    - `logs` contains the logs of all major actions:
+      - `dspot.log` is the log of the dspot execution.
+      - `git_clone.log` is the log of the `git clone` command.
+      - `git_pull.log` is the log of the last `git pull` command, if relevant.

+# DSpot Web UI
+
+## About
+
+This directory contains everything needed to run a demonstration web server for DSpot.
+
+
+## Installation
+
+This application uses the [Mojolicious web framework](https://mojolicious.org/) and relies on a Postgres DB to store the task management system. Results are stored on disk.
+
+You will need to install Perl and Mojolicious, plus a few other plugins. It is good practice to use [perlbrew](https://perlbrew.pl/) to manage one's perl installation, although it is not required. Then requirements can be installed with:
+
+```
+$ cpanm Mojolicious
+$ cpanm Mojolicious::Plugin::Minion Mojolicious::Plugin::Minion::Admin Mojolicious::Plugin::Mail
+$ cpanm Mojo::Pg
+$ cpanm Archive::Zip File::Copy::Recursive DateTime
+```
+
+### Initialising the application
+
+Setup a PostgreSQL DB for Minion:
+
+```
+postgres=# CREATE USER dspot_minion WITH PASSWORD 'pass4minion';
+CREATE ROLE
+postgres=# CREATE DATABASE dspot_minion OWNER dspot_minion;
+CREATE DATABASE
+```
+
+
+## Run the application
+
+```
+$ hypnotoad script/dspot_web
+```
+
+The application is served on http://localhost:3000.
