 **batsched** is a set of [Batsim]-compatible algorithms implemented in C++.
 
-## Install
-### For [Nix] users
-``` bash
-# Up-to-date version
-nix-env -iA batsched-master -f 'https://github.com/oar-team/nur-kapack/archive/master.tar.gz'
-# Latest release
-nix-env -iA batsched -f 'https://github.com/oar-team/nur-kapack/archive/master.tar.gz'
-```
+## Development setup prerequisites
+1. Install Nix with the `nix` command and nix `flakes` enabled.
+   This can be done via [nix-portable](https://github.com/DavHau/nix-portable) or with a [full install](https://nixos.org/download) + [configuration](https://nixos.wiki/wiki/Flakes#Other_Distros.2C_without_Home-Manager).
 
-### Manually
-``` bash
-git clone https://framagit.org/batsim/batsched.git
-mkdir -p batsched/build
-cd batsched/build
-cmake ..
-make
-make install
-```
+## Dev workflow 1 (pure build every time)
+1. Hack some input files.
+2. (if you have added new files to Git that are needed to compile batsched, you must `git add` them)
+3. Build batsched via `nix`: `nix build .#batsched` from the git repository's root.
+4. Use the `batsched` that has been compiled. It is available in `./result/bin/batsched`
 
-Up-to-date dependencies and versions are fully defined in [batsched's CI nix recipe](./release.nix).  
-Here is a quick (and probably outdated) list:
-- decent clang/gcc and cmake
-- zmq (C and C++)
-- redox (hiredis + libev)
-- [loguru]
-- [intervalset]
-- decent boost, gmp, rapidjson...

+## Dev workflow 2 (iterative builds)
+1. Hack some input files.
+2. Enter a shell that you'll use to compile batsched: `nix develop .#batsched`.
+   In this shell you can compile batsched how you'd do without Nix:
+   - `meson setup build` once
+   - then `ninja -C build` everytime you want to compile batsched
+3. Use the `batsched` that has been compiled. It is available in `./build/batsched`
