+# Support
+
+Thank you for using Erlang LS! :tada:
+
+This document offers some guidelines when asking for support related to an issue
+you might be having with the Erlang LS tool.
+
+# Guidelines
+
+These are some general guidelines to follow when reaching out through any of the
+available support channels.
+
+1. **Search through the existing
+   [issues](https://github.com/erlang-ls/erlang_ls/issues/) before opening a new
+   one**
+
+   Check if one already exists related to the issue you are having. Remember
+   to include `closed` issues as well.
+
+2. **Provide as much context and information as possible**
+
+   It is much more likely that others will be able to help you if they can
+   reproduce the issue your are experiencing.
+
+3. **Be nice**
+
+   This can be applied to life in general, but it's specially important when
+   communicating only through written text.
