+
+1 - Boot the container `docker-compose up -d graylog`
+
+2 - Open your Laravel's `.env` file and set the `GRAYLOG_PASSWORD` to some passsword, and `GRAYLOG_SHA256_PASSWORD` to the sha256 representation of your password (`GRAYLOG_SHA256_PASSWORD` is what matters, `GRAYLOG_PASSWORD` is just a reminder of your password).
+
+> Your password must be at least 16 characters long
+> You can generate sha256 of some password with the following command `echo -n somesupersecretpassword | sha256sum`
+
+```env
+GRAYLOG_PASSWORD=somesupersecretpassword
+GRAYLOG_SHA256_PASSWORD=b1cb6e31e172577918c9e7806c572b5ed8477d3f57aa737bee4b5b1db3696f09

+# GRAYLOG CONFIGURATION FILE
+############################
+#
+# This is the Graylog configuration file. The file has to use ISO 8859-1/Latin-1 character encoding.
+# Characters that cannot be directly represented in this encoding can be written using Unicode escapes
+# as defined in https://docs.oracle.com/javase/specs/jls/se8/html/jls-3.html#jls-3.3, using the \u prefix.
+# For example, \u002c.
+#
+# * Entries are generally expected to be a single line of the form, one of the following:
+#
+# propertyName=propertyValue
+# propertyName:propertyValue
+#
+# * White space that appears between the property name and property value is ignored,
+#   so the following are equivalent:
+#
+# name=Stephen
+# name = Stephen
+#
+# * White space at the beginning of the line is also ignored.
+#
+# * Lines that start with the comment characters ! or # are ignored. Blank lines are also ignored.
+#
+# * The property value is generally terminated by the end of the line. White space following the
+#   property value is not ignored, and is treated as part of the property value.
+#
+# * A property value can span several lines if each line is terminated by a backslash (‘\’) character.
+#   For example:
+#
+# targetCities=\
+#         Detroit,\
+#         Chicago,\
+#         Los Angeles
+#
+#   This is equivalent to targetCities=Detroit,Chicago,Los Angeles (white space at the beginning of lines is ignored).
+#
+# * The characters newline, carriage return, and tab can be inserted with characters \n, \r, and \t, respectively.
+#
+# * The backslash character must be escaped as a double backslash. For example:
+#
+# path=c:\\docs\\doc1

+#### HTTP bind address

+# using the Graylog web interface.

+# If the port is omitted, Graylog will use port 9000 by default.

+#
+# The HTTP URI of this Graylog node which is used to communicate with the other Graylog nodes in the cluster and by all
+# clients using the Graylog web interface.

+#
+# The external Graylog URI usually has to be specified, if Graylog is running behind a reverse proxy or load-balancer
+# and it will be used to generate URLs addressing entities in the Graylog REST API (see $http_bind_address).
+#
+# When using Graylog Collector, this URI will be used to receive heartbeat messages and must be accessible for all collectors.
