 # Installation
+Two install methods are described below - the easiest method is to install with conda.
+
+## Installation from conda
+To install from conda, first you will need to install [conda](https://conda.io/projects/conda/en/latest/user-guide/install/index.html?highlight=conda#).
+
+The conda install requires the channels `bioconda` and `conda-forge`. You can install ISMapper as its own environment using `conda create`: 
+```
+conda create -n ismapper-bioconda -c conda-forge -c bioconda ismapper
+```
+
+To use ISMapper, type
+```conda activate ismapper-bioconda```
+
+## Installation with pip
 Install Python and its dependencies first.
