+# Telegram Bot - Web Check
+Little depless bot for telegram that checks if a site is up or down by the HTTP code
+
+## Requirements
+You need a telegram bot for this, so for that you should follow the official
+documentation:
+
+[https://core.telegram.org/bots](https://core.telegram.org/bots)
+
+Or just "talk" with the following bots and follow the steps:
+
+[Bot Father](https://t.me/botfather)
+[Bot ID](https://t.me/idbot)
+
+## Usage
+I'm using this in a really simple way, just to get an extra check from
+"outside" of my websites besides my real monitoring system.
+
+### List of sites
+```
+$ pwd
+/home/gonzalo/monitoring
+$ cat webs.txt
+openbsd.org
+foobar.org
+foobar.com
+f00bar.org
+f00bar.com
+poop.org
+poop.com.ar
+$ touch /var/log/web-checks.log
+$ doas chown gonzalo:gonzalo /var/log/web-checks.log
+$ for i in $(cat webs.txt); do sh tg-webcheck $i; done
+```
+
+### Just one site
+```
+$ pwd
+/home/gonzalo/monitoring
+$ touch /var/log/web-checks.log
+$ doas chown gonzalo:gonzalo /var/log/web-checks.log
+$ sh tg-webcheck poop.org
+```
