# NeuroSploit installer for Windows (PowerShell) — by Joas A Santos & Red Team Leaders
#
#   irm https://raw.githubusercontent.com/JoasASantos/NeuroSploit/main/install.ps1 | iex
#
# Downloads the prebuilt neurosploit.exe + agent library, installs them, and sets
# your User PATH + NEUROSPLOIT_BASE so you can run `neurosploit` from ANY folder —
# no need to cd into the repo. Falls back to building from source if needed.
# Env: NEUROSPLOIT_DIR (install dir), NEUROSPLOIT_REF (release tag),
#      NEUROSPLOIT_BUILD=1 (force source build).
