+
+
+## TL;DR
+
+### Add button support
+
+1. Edit `/boot/config.txt` file.
+2. Add line ` dtoverlay=gpio-shutdown`.
+
+Final result:
+```
+[...]
+
+[all]
+# enable raspicam
+start_x=1
+gpu_mem=128
+
+# Simple button on/off
+dtoverlay=gpio-shutdown
+```
+
+### Add LED support 
+
+1. Edit crontab
+```
+#> crontab -e
+```
+
+
+2. Add the line
+```
+@reboot raspi-gpio set 4 op dh
+```
+
+Final result:
+```
+# Edit this file to introduce tasks to be run by cron.
+#
+# Each task to run has to be defined through a single line
+# indicating with different fields when the task will be run
+# and what command to run for the task
+#
+# To define the time you can provide concrete values for
+# minute (m), hour (h), day of month (dom), month (mon),
+# and day of week (dow) or use '*' in these fields (for 'any').
+#
+# Notice that tasks will be started based on the cron's system
+# daemon's notion of time and timezones.
+#
+# Output of the crontab jobs (including errors) is sent through
+# email to the user the crontab file belongs to (unless redirected).
+#
+# For example, you can run a backup of all your user accounts
+# at 5 a.m every week with:
+# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
+#
+# For more information see the manual pages of crontab(5) and cron(8)
+#
+# m h  dom mon dow   command
+@reboot raspi-gpio set 4 op dh
+```
