replace with FastCGI instructions via php-cgi.exe - Remove NO_AUTO_CREATE_USER from sql_mode (removed MySQL 8.0, breaks startup) - sort_buffer_size = 200M → 32M with caveat (per-session; 200M causes OOM under load) - Fix step numbering gaps: main list 5→8, IIS 3→5, Finishing 5→8 - "you will have to user 8.3 notation" → "use" - "c:cygwin" → "c:\cygwin" (missing backslash) - "it's subfolders" → "its subfolders" - "A anm example" → "An example" - "verify/udate" → "verify/update" Installing-Under-Ubuntu-Debian.md: - Cron user: apache → www-data (apache user does not exist on Ubuntu/Debian) - CREATE DATABASE: use utf8mb4 directly;

Point the snmpd.conf link at www.net-snmp.org (the sourceforge.io mirror is bot-blocked). Fix 'There a two ways extending' to 'There are two ways to extend'. Signed-off-by: Thomas Vincent <thomasvincent@gmail.com> * ci: fix spelling workflow trigger to target develop, not main The repo's default branch is develop; main hasn't moved since 2023. The workflow's push/pull_request filters targeted main, so it never ran on any PR opened against develop.
