 # Advent-of-Code 2016
 *This is a dumbed down version of [fspoettel/advent-of-code-rust](https://github.com/fspoettel/advent-of-code-rust) with some extra features*
 
 ## Project overview
 
 ### Project structure
+- `data/` :
+    - `examples/`: example files go here; you can push this as test are run in ci
+    - `inputs/`: this directory is gitignored, input files go here
 - `src/` :
     - `bin/`:
         - `<day>.rs`: solution files 
-        - `*.rs`: convenience scripts
+    - `lib.rs`: library entrypoint, reusable code goes here
-    - `inputs/`: this directory is gitignored, input files go here
+    - `template.rs`: contains template code
-    - `examples/`: example files go here; you can push this as test are run in ci
+- `utils/`: binary packages with convenience scripts structured using cargo workspaces
-    - `utils/`: utils files go here
-    - `lib.rs`: contains framework code
-    - `main.rs`: contains framework code
 - `.env.example`: example dotenv file
 
 ### Cli
 - `cargo scaffold <day>`: prepare solution files for `day`
 - `cargo download <day>`: download input file for `day`
 - `cargo solve <day>`: run solution against input for `day`
-- `cargo all`: alias for run; runs solutions for all days
 
+*Run `cargo build --workspace --release` once so scaffold and download packages get compiled, otherwise they will have to be compiled on first run.*
 
 ### dotenv
