+# Checks project Markdown files for spelling mistakes.
+
+# Notes:
+
+# This script needs dictionary file ($dict_filename) with project-specific
+# valid words. If this file is missing, first invocation of a script generates
+# a file of words considered typos at the moment. User should remove real typos
+# from this file and leave only valid words. When script generates false
+# positive after source modification, new valid word should be added
+# to dictionary file.
+
+# Default mode of this script is interactive. Each source file is scanned for
+# typos. aspell opens window, suggesting fixes for each found typo. Original
+# files with errors will be backed up to files with format "filename.md.bak".
+
+# When running in CI, this script should be run in "list" mode (pass "list"
+# as first argument). In this mode script scans all files and reports found
+# errors. Exit code in this case depends on scan result:
+# 1 if any errors found,
+# 0 if all is clear.
+
+# Script skips words with length less than or equal to 3. This helps to avoid
+# some false positives.
+
+# We can consider skipping source code in markdown files (```code```) to reduce
+# rate of false positives, but then we lose ability to detect typos in code
+# comments/strings etc.
