+** TODO List
+- [ ] Reminders
+
+** Setup
+
+*** Prerequisites
+
+- [[https://docs.haskellstack.org/en/stable/README/][The Haskell tool stack]] ([[./stack-arm.org][installing stack on ARM64]])
+
+*** Building
+
+#+begin_src sh
+git clone 'https://git.annwan.me/Annwan/botiut'
+cd botiut
+stack setup
+stack build
+#+end_src
+
+*** Configuring
+
+- Put your discord token in =auth.secret= in the working directory,
+  without trailing new lines
+
+- Put the yaml format configuration in =conf.yaml=. An commented
+  configuration example is given in [[./conf.example.yaml][conf.example.yaml]].
+
+*** Running
+
+There is two options
+
+1) Run =stack run= from the repository
+
+2) Copy the executable somewhere else, then call it from the expected
+   working directory.

+** Why stack on ARM
+
+People might want to run haskell applications on ARM devices like a
+Raspberry Pi. The Haskell compiler has supported the architecture
+through LLVM for a couple of year now, as well as the builtin dependency
+manager, Cabal. However the dependency management of Cabal is
+system-wide (or at least user wide) and, because all packages interact
+with each other, it can pose problems with compatibility.
+
+That is the problem that =stack= solves by allowing for reproducible,
+isolated environement for each project, and a lot of projects now use
+stack for their dependency and version management.
+
+However stack does not provide any build for arm systems, we thus need
+to install it anoter way
