+# Building TUV-x on Derecho 
+
+## Get the source code
+
+- Copy the build script you wish to use from this folder to GLADE.
+  There are scripts for GNU and Intel compilers, without MPI support.
+
+- Log in to Derecho
+
+- Create a directory to build TUV-x in:
+
+```
+mkdir my-tuvx-build
+```
+
+- Create an environment variable named `TUVX_HOME` pointing to the absolute path of your build directory:
+
+```
+export TUVX_HOME=/path/to/my-tuvx-build
+```
+
+## Build TUV-x
+
+Replace `/path/to/build_tuvx_derecho_X.sh` with the path to the build script you copied to GLADE, in the following:
+
+```
+cd $TUVX_HOME
+. /path/to/build_tuvx_derecho_X.sh
+```
+
+## Run TUV-x
+- Whenever you go to run TUV-x after it has been built, make sure you have the correct environment modules loaded.
+  Look at the top of the build script you used to find the modules required.
+
+- Run a test. The tests use the python numpy package, and we access this through the conda environment module on Derecho:
+
+```
+module load conda
+conda activate npl
+cd $TUVX_HOME/tuv-x-private/build
+make test
+```
+
+- Run a configuration (this does not require any Python packages)
+
+```
+cd $TUVX_HOME/tuv-x-private/build
+./tuv-x examples/full_config.json
+```
+
