+This page is about how ShellCheck reports parser errors, to aid you in finding problems. If you're getting a parser error for code you know or think is correct, you should [submit a bug](https://github.com/koalaman/shellcheck/issues/new) with an example!
+
+When ShellCheck is unable to parse a file, it'll output several errors to help pinpoint the problem:
+
+Consider this script, with a missing double quote on line 1:
+
+    ssh host "$cmd
+    echo "Finished"
+
+Bash says:
+
+    file: line 2: unexpected EOF while looking for matching `"'
+    file: line 3: syntax error: unexpected end of file
+
+Shellcheck says:
+
+    In file line 1:
+    ssh host "$cmd
+    ^-- SC1009: The mentioned parser error was in this simple command.
+
+    In file line 2:
+    echo "Finished"
+                  ^-- SC1073: Couldn't parse this double quoted string.
+                   ^-- SC1072: Unexpected eof. Fix any mentioned problems and try again.
+
+
+1. One error showing the direct problem (SC1072, unexpected eof) *(Note: see [#1036](../issues/1036))*
+1. One error showing the construct being parsed (SC1073)
+1. One info showing the outer construct being parsed (SC1009)
+1. Potentially some specific suggestions, such as when missing an `fi`.
+
+Here, shellcheck says that the command on line 1 is faulty, which makes it easier to find and fix the actual problem.
+
+Most of ShellCheck's functionality (specifically, any checks with code >= SC2000) only applies to scripts that parse successfully, so make sure to rerun ShellCheck after fixing any syntax errors.
