+### NOTE:
+Using custom version of poise (the discord library) because I need to use a specific version of serenity (the discord library for poise). Here's how to set it up:
+
+1) Clone Poise next to this repo:
+
+```shell
+git clone https://github.com/serenity-rs/poise.git
+```
+
+2) Change the version of serenity that poise uses:
+
+```diff
+[dependencies.serenity]
+- version = "x.xx.x"
++ git = "https://github.com/serenity-rs/serenity.git"
++ rev = "e34f4491ee3a0b20ea8dc30cbc77b257f402f692"
+```
+
+> Just make sure that the rev is a sha1 commit hash sometime after 7/25/24
