so I wanna submit a run (done by streaming to clarify incase there are any twitch requirements) and I just wanna know if I need livesplit or any external installations to do a proper speedrun on here any help is thanked

from the game rules: "All runs HAVE to be submitted with some sort of proof in form of a video or demos. In case of suspicion demos can be requested by the mods. Videos have to show the full run from start to finish. Video must be hosted on a permanent video platform, such as Youtube or a Twitch Highlight. Temporary platforms such as Streamable or your Twitch VOD are not acceptable. If you are submitting Time without loads with only video proof, the video has to show Livesplit comparing against Gametime throughout the entire run". It's also advisable to install Source Unpack Version 2.4 at https://sourceunpack.gameabusefastcomplete.com/ because the newest steam version has some glitches patched. You should also probably watch the setup guide and how to submit a run in the guide section.
