+# Setting up a development environment
+
+
+In order to ensure that what you'll be experiencing during development will be
+what the end-user will experience in terms of stability, performance and
+compatibility, the preferred way to setup a development environment is
+to essentially work from inside one of Arachni's self-contained packages.
+
+Actually, this makes setting up a development environment even easier as
+you won't have to go digging through dependencies or affecting the libraries
+and packages of your workstation at all.
+
+All this goodness is facilitated by the project's [build scripts](https://github.com/Arachni/build-scripts).
+
+The following will build and setup a self-contained environment for you:
+
+    ARACHNI_BUILD_ENV=development wget -O - https://raw.github.com/Arachni/build-scripts/master/bootstrap.sh | bash
+
+The ```ARACHNI_BUILD_ENV=development``` env tells the build-scripts to preserve
+development headers of all the libraries it installs so that you'll be able to
+install more gems inside that env if need be.
+
+Finally, if you are using RVM, put this in your ```.rvmrc``` file:
+
+    # Clear RVM's env overrides to make room for ours
+    rvm reset
+
+    # Get us into the package env
+    export env_root=/home/<username>/arachni-build-dir/arachni/system
+    source $env_root/environment
+    export PATH=$env_root/gems/bin:$PATH
+
+If not using RVM you'll have to run the above manually when working with the
+terminal while developing Arachni.
