+# How To Install GAMS
+
+## Download the proper GAMS version
+
+Download the proper GAMS version from https://www.gams.com/latest/ (notice that older versions are found in the `Previous Distributions` box).
+Notice that the **GNU/Linux Systems** version is required for HPC systems.
+
+## Manual installation of GAMS
+
+GAMS is shipped through an executable file, which will expand all files into a single directory.
+
+1. Create a directory for the new version. Example for version 42.3.0:
+```bash
+mkdir -p /opt/psi/Tools/GAMS/42.3.0
+```
+2. Copy the executable to the new created directory
+```bash
+mv linux_x64_64_sfx.exe /opt/psi/Tools/GAMS/42.3.0/
+```
+3. Change permissions of the executable accordingly
+```bash
+chmod +x /opt/psi/Tools/GAMS/42.3.0/linux_x64_64_sfx.exe
+```
+4. Execute it to install the software
+```bash
+cd /opt/psi/Tools/GAMS/42.3.0
+./linux_x64_64_sfx.exe
+```
+5. The created subdirectory is created with the pattern: `gams${v_MAJOR}.${V_MINOR}_linux_x64_64_sfx`. Examples:
+```bash
+/opt/psi/Tools/GAMS/31.1.1/gams31.1_linux_x64_64_sfx
+/opt/psi/Tools/GAMS/42.3.0/gams42.3_linux_x64_64_sfx
+```
+6. Add the proper version in the variants file and run the build file
+```bash
+cd ~/buildblocks/Tools/GAMS
+echo "GAMS/42.3.0   unstable" >> files/variants.rhel7
+./build 42.3.0
+```
+
