+cnotes v0.1.1 for DOS
+=====================
+
+A simple command-line note-taking system
+Built with Turbo C++ 3.0 (large memory model)
+
+WHAT IS THIS?
+------------
+cnotes lets you quickly add, view, search, count, and archive short notes
+from the DOS prompt. Notes are saved in plain cnotes.csv in your notes
+directory (usually current directory on DOS).
+
+COMMANDS INCLUDED
+-----------------
+CNADD    - Add a new note
+CNDUMP   - Show all notes in a table
+CNCOUNT  - Show statistics (total, by category, by date)
+CNDEL    - Archive (move) notes to cnotes.arc
+CNFIND   - Search notes by text/category/date
+CNHELP   - Show this help overview
+
+INSTALLATION
+------------
+1. Unzip all files to any directory (e.g. C:\TEMP)
+2. Run INSTALL.BAT from that directory
+3. Follow the on-screen prompts
+
+After installation:
+- Best: add C:\CNOTES to your PATH
+  SET PATH=%PATH%;C:\CNOTES
+  (put this line in C:\AUTOEXEC.BAT to make it permanent)
+- Or run commands with full path: C:\CNOTES\CNADD "Test note"
+
+QUICK START
+-----------
+CNADD "Remember to call Bob"
+CNADD -c Work "Meeting 3pm tomorrow"
+
+CNDUMP          - view all notes
+CNHELP          - full command help
+CNHELP cnadd    - help for one command
+
+NOTES LOCATION
+--------------
+By default: current directory (cnotes.csv and cnotes.arc)
+Override with environment variable:
+  SET CNOTES_PATH=C:\MYNOTES
+
+Have fun logging notes the retro way!
