+# Using this container on Cheaha
+
+You will need to follow these instructions:
+
+1. If you already cloned the Alphafold3 [github repo](https://github.com/google-deepmind/alphafold3), you do not need to clone this repo. But if you have not, you can clone this gitlab repo.
+1. Download the needed databases for Alphafold3 by running the command. Make sure you are in the same folder as the `fetch_databases.sh` file before running the below command, or use the absolute file path to run it.
+
+    ``` bash
+
+    ./fetch_databases.sh <DB_DIR> #<DB_DIR> is your preferred location for storing the databases
+
+    ```
+1. Now pull the container with singularity using 
+
+    ``` bash
+
+    singularity pull alphafold3.sif docker://gitlab.rc.uab.edu/rc-data-science/community-containers/Alphafold3/
+
+    ```
+1. When the above step is completed, you can now run the Alphafold3 container on Cheaha using the command to test it out.
+
+    ``` bash
+
+    singularity exec --nv alphafold3.sif sh -c 'nvidia-smi'
+
+    ```
