This fixes several typos and improves clarity in the README.md file, including:

• Corrected "give" to "given" and added articles (e.g., "a list") for grammatical accuracy.
• Standardized "CIDR" capitalization and pluralization (e.g., "CIDRs").
• Changed "In order to" to "To" for conciseness.
• Fixed "mapCDIR" to "mapCIDR" in the footer.
• Corrected duplicate command description in the "Match / Filter IPs from CIDR" section.
• Improved punctuation and formatting consistency (e.g., added colons after commands).
