 Notes on worktrees (`try .` / `try worktree dir`):
-- With a custom [name], uses that; otherwise uses cwd’s basename. Both are prefixed with today’s date.
+- `try .` requires a name (`try . <name>`).
+- `try ./path/to/repo [name]` and `try worktree dir [name]` use cwd basename when name is omitted.
 - Inside a Git repo: adds a detached HEAD git worktree to the created directory.
 - Outside a repo: simply creates the directory and changes into it.

+### Environment Variables
+
+- `TRY_PATH` - Where experiments are stored (default: `~/src/tries`)
+- `TRY_PROJECTS` - Graduate destination for promoted experiments (default: parent of `TRY_PATH`)
+- `NO_COLOR` - Disable colored output when set
 
 ```bash
 export TRY_PATH=~/code/sketches
+export TRY_PROJECTS=~/projects
 ```
 
-Default: `~/src/tries`
+### Command Line Flags
