+Thank you for submitting a Pull Request. Please:
+* Read our commit style guide:
+    Commit messages should adhere to the following points:
+    * Separate subject from body with a blank line
+    * Limit the subject line to 50 characters as much as possible
+    * Capitalize the subject line
+    * Do not end the subject line with a period
+    * Use the imperative mood in the subject line
+    * The verb should represent what was accomplished (Create, Add, Fix etc)
+    * Wrap the body at 72 characters
+    * Use the body to explain the what and why vs. the how
+  For an example, look at the following link:
+  https://docs.dissect.tools/en/latest/contributing/style-guide.html#example-commit-message
+
+* Include a description of the proposed changes and how to test them.
+
+* After creation, associate the PR with an issue, under the development section.
+  Or use closing keywords in the body during creation:
+  E.G:
+  * close(|s|d) #<nr>
+  * fix(|es|ed) #<nr>
+  * resolve(|s|d) #<nr>
