+## Running simplecontainer as the root
+Running start commands as the root user will not start and configure simplecontainer correct.
+```cgo
+smrmgr start 
+```
+The command above needs to run as the user who is not root and has correct access to the `/var/run/docker.sock`.
+
+## Docker socket access is not correctly configured
+Simplecontainer relies on the `/var/run/docker.sock` to communicate with the docker engine.
+
+### Option 1: Make user owner of the socket (Temporary solution)
+```cgo
+sudo chown $USER /var/run/docker.sock
+```
+
+### Option 2: Add user to the group that has access to the /var/run/docker.sock (Permanent solution)
+```cgo
+GROUP_NAME=$(stat -c '%G' /var/run/docker.sock)
+sudo usermod -aG "$GROUP_NAME" "$USER"
+```
