+# Olex2
 
-Step 1: login with your -adm account
+Olex2 is a free, open-source software program used for determining, visualizing, and analyzing small-molecule crystal structures. It provides a comprehensive and user-friendly graphical interface to guide users through the process of crystal structure solution, refinement, and report generation. This workflow-oriented program is designed to be useful for both experienced crystallographers and chemists who may not have specialized training.
 
-```
-[smith_k@ra-l-005 xds]$ kinit smith_k-adm
-[smith_k@ra-l-005 xds]$ aklog
-```
-
-Step 2: load the latest Pmodules package
-
-```
-module use unstable
-module load Pmodules/2.0.0
-```
-
-Step 3: go into olex2 directory, update config.yaml to add newest release version and build module with that release name (e.g. below is for 1.5)
-
-```
-cd olex2
-vi files/config.yaml
-./build 1.5
-```
-
-Step 4: confirm that the module loads as expected 
+## Installation guide
+1. First, download the zip archive with the binaries. For example for version 1.5, it was download from https://secure.olex2.org/olex2-distro/1.5/olex2-linux64.zip
+2. Build the module with the correct version.
