+## TL:DR
+
+```sh
+# Show what kernel modules are currently loaded.
+lsmod
+
+# Show information about a module.
+modinfo 'module_name'
+
+# List the options set for loaded modules.
+systool -v -m 'module_name'
+
+# Show the comprehensive configuration of modules.
+modprobe -c
+modprobe -c | grep 'module_name'
+
+# List the dependencies of modules or aliases.
+# Includes the module itself.
+modprobe --show-depends 'module_name'
+
+# Load modules.
+modprobe 'module_name'
+modprobe 'module_name' 'parameter_1=value' 'parameter_n=value'
+
+# Load modules by file name.
+# For those not installed in "/usr/lib/modules/$(uname -r)/".
+insmod 'file_name' 'arg_1' 'arg_n'
+
+# Unload modules.
+modprobe -r 'module_name'
+rmmod 'module_name'
+```
+
+## Permanent modules configuration
+
+Write the options in a `.conf` file in `/etc/modprobe.d/`:
+
+```conf
+# /etc/modprobe.d/raspi-wifi-workaround.conf
+options brcmfmac roamoff=1 feature_disable=0x82000
