+
+Installation
+------------
+
+*magic-cta-pipe* and its dependencies may be installed using the *Anaconda* or *Miniconda* package system. We recommend creating a conda virtual environment
+first, to isolate the installed version and dependencies from your master environment (this is optional).
+
+The following command will set up a conda virtual environment, add the necessary package channels, and install *magic-cta-pipe* and its dependencies::
+
+.. code-block:: console
+
+    git clone https://github.com/cta-observatory/magic-cta-pipe.git
+    cd magic-cta-pipe
+    conda env create -n magic-lst1 -f environment.yml
+    conda activate magic-lst1
+    pip install .
