 You need to set up a quick local database for development without polluting your environment.
 
-## Method 1 (Using Guix)
+## Method 1 (Using Guix system containers)
 
 Setting up mariadb in a Guix container is the preferred and easier method. But, you need root access to run the container. The genenetwork2 repo comes with a guix system container definition to run MariaDB and Redis. From the genenetwork2 repo, you can build and run the container using:

+## Method 2 (running a local container)
+
+A local container runs as a normal user. It requires some juggling of dirs to load an existing database. Make sure to not run on the same dirs as another mariadb instance(!)
+

+cd ~/tmp/mariadb
+mkdir var
+~/tmp/mariadb$ ~/opt/guix-pull/bin/guix shell -C -N coreutils binutils sed mariadb --expose=var
+```
+
+inside the container
+
+```
+mkdir -p /var/lib/data
+mkdir -p /var/lib/mysql
+mkdir /var/run
+```
+
+Initialize with
+
+```
+mysql_install_db
+```
+
+and run
+
+```
+mysqld_safe --datadir='./data' --user=$USER --nowatch --socket=/var/run/mysqld/mysqld.sock
+```
+
+Now from outside the container you should be able to connect with

+If you need to tweak the server configuration you can load the my.cnf file with the `--defaults-file=var/my.cnf` inside and outside the container.

 * We install the database files under ~/genenetwork/mariadb. Change as appropriate.
