+# Introduction
+
+This web-server for running the i2p-website is a collection of scripts (aka **The Python Scripts**) and content-files to:
+
+* manage updates (based on git),
+* manage translations (generating translation files before the web-server is run),
+* manage tags (generating tag files before the web-server is run),
+* run a web-server creating/delivering pages on-demand (using WSGI)
+
+This is not a static web-site generator. To see the pages you will need to setup your system for the python and shell-scripts and run the web-server contained as described. Due to heavy use of tags even content changes quickly will require a *build environment* to check your changes (towards breaking the build process). Translations can be done using solely a web-site and then do not require any of this (others will integrate all changes from the web-site using these scripts).
+
+The authors are the I2P team. For details about licensing see [LICENSE.txt](/LICENSE.txt).

+
+# Requirements Overview
+
+If you don't want to deal with the requirements/software, you can use a docker config (see [Dockerfile](/Dockerfile)) which will set these up automatically. Otherwise you will need to satisfy the following requirements (that Dockerfile contains the commands for Debian btw.):
+
+* git
+* python2
+* pip
+* virtualenv
+* apache (using WSGI to call the scripts)
+* ctags? (was mentioned to be needed as both, system package + python package, but it seems only the python package is being installed?)
+* transifex-client? (There is a transifex-client in Debian which might be needed for the translation steps described below?)
+
+**Note** that the scripts will install additional software packages (see /etc/reqs.txt) from outside your distribution (into the virtual environment if using docker) using pip and then do some custom patching (meaning pinned versions?). 
+
+**Note** also that the manual way described in the following suggests to use proxychains with Tor to avoid Clearnet traffic, while the Docker version seems to use Clearnet for that.
