+
+gitnow is a CLI tool for discovering, cloning, and navigating git repositories
+from multiple providers (GitHub, Gitea). It maintains a local cache of known
+repositories and provides fuzzy-search, interactive selection, worktree
+management, and scratch-pad project workspaces.
+
+## Quick reference
+
+```
+gitnow [OPTIONS] [SEARCH]            # search/clone/open a repository
+gitnow update                        # refresh the local repository cache
+gitnow clone --search <REGEX>        # batch-clone repositories matching a pattern
+gitnow worktree [SEARCH] [OPTIONS]   # create and enter a git worktree for a branch
+gitnow project [SEARCH] [OPTIONS]    # open an existing scratch-pad project
+gitnow project create [NAME]         # create a new multi-repo project
+gitnow project add [NAME]            # add repositories to a project
+gitnow project delete [NAME]         # delete a project
+gitnow init zsh                      # print zsh shell integration script
+gitnow skill                         # print this reference (you are here)
+```
+
+## Commands in detail
+
+### Default (no subcommand)
+
+```
+gitnow [OPTIONS] [SEARCH]
+```
+
+Search for a repository, optionally clone it, and open a shell inside it.
+
+- If SEARCH is provided, fuzzy-matches against cached repositories.
+- If omitted, opens an interactive fuzzy-search picker.
+- Clones the repository if it does not exist locally.
+- Spawns a sub-shell in the repository directory.
+
+**Flags:**
+| Flag                  | Description                                              |
+|-----------------------|----------------------------------------------------------|
+| `--no-cache`          | Skip reading from the local cache; fetch fresh data      |
+| `--no-clone`          | Do not clone the repository if it is missing locally     |
+| `--no-shell`          | Print the path instead of spawning a shell               |
+| `--force-refresh`     | Force a fresh clone even if the repo already exists      |
+| `--force-cache-update`| Update the cache before searching                        |
+| `--chooser-file PATH` | Write selected path to this file (implies --no-shell)   |
+| `-c, --config PATH`  | Path to config file (global flag)                        |
+
+**Environment variables:**
+- `GITNOW_CONFIG` — path to config file (overrides default)
+- `GITNOW_CHOOSER_FILE` — equivalent to `--chooser-file`
+
+---
+
+### `gitnow update`
+
+Fetch all repositories from configured providers and update the local cache.
+Should be run periodically or after adding new providers/organisations.
+
+No flags.
+
+---
+
+### `gitnow clone --search <REGEX>`
+
+Batch-clone all repositories whose relative path matches the given regex.
+Clones up to 5 repositories concurrently. Skips repos that already exist locally.
+
+**Required flags:**
+| Flag               | Description                                |
+|--------------------|--------------------------------------------|
+| `--search <REGEX>` | Regular expression to match repository paths |
+
+---
+
+### `gitnow worktree [SEARCH] [OPTIONS]`
+
+Create a git worktree for a specific branch of a repository. This is useful for
+working on multiple branches simultaneously without switching.
+
+**Workflow:**
+1. Select a repository (fuzzy search or interactive picker)
+2. Bare-clone the repository if not already present
+3. List remote branches
+4. Select a branch (interactive picker, or `--branch`)
+5. Create a worktree directory at `<project>/<sanitized-branch>/`
+6. Spawn a shell in the worktree (or write path to chooser file)
+
+**Flags:**
+| Flag              | Description                                    |
+|-------------------|------------------------------------------------|
+| `[SEARCH]`        | Optional search string to pre-filter repos     |
+| `-b, --branch`    | Branch name (skips interactive branch picker)   |
+| `--no-cache`      | Skip the local cache                           |
+| `--no-shell`      | Print path instead of spawning a shell         |
+
+---
+
+### `gitnow project [SEARCH] [OPTIONS]`
+
+Manage scratch-pad projects — directories containing multiple cloned repositories,
+optionally bootstrapped from a template.
+
+When called without a subcommand, opens an existing project (interactive picker
+or fuzzy match on SEARCH).
+
+**Flags:**
+| Flag         | Description                              |
+|--------------|------------------------------------------|
+| `[SEARCH]`   | Filter existing projects by name         |
+| `--no-shell` | Print path instead of spawning a shell   |
+
+#### `gitnow project create [NAME] [OPTIONS]`
+
+Create a new project directory, interactively select repositories to clone into it,
+and optionally apply a template.
+
+| Flag                | Description                                          |
+|---------------------|------------------------------------------------------|
+| `[NAME]`            | Project name (prompted if omitted)                   |
+| `-t, --template`    | Template name to bootstrap from                      |
+| `--no-cache`        | Skip local cache when listing repos                  |
+| `--no-shell`        | Print path instead of spawning a shell               |
+
+Templates live in `~/.gitnow/templates/` (or the configured directory). Each
+subdirectory is a template; its contents are copied into the new project.
+
+#### `gitnow project add [NAME] [OPTIONS]`
+
+Add more repositories to an existing project.
+
+| Flag         | Description                              |
+|--------------|------------------------------------------|
+| `[NAME]`     | Project name (interactive if omitted)    |
+| `--no-cache` | Skip local cache when listing repos      |
+
+#### `gitnow project delete [NAME] [OPTIONS]`
+
+Delete a project directory.
+
+| Flag          | Description                          |
+|---------------|--------------------------------------|
+| `[NAME]`      | Project name (interactive if omitted)|
+| `-f, --force` | Skip confirmation prompt             |
+
+---
+
+### `gitnow init zsh`
+
+Print a zsh shell integration script to stdout. Typically used as:
+
+```zsh
+eval "$(gitnow init zsh)"
+```
+
+This provides a shell function that changes directory after gitnow exits,
+using the chooser-file mechanism.
+
+---
+
+### `gitnow skill`
+
+Print this LLM-readable reference document to stdout.
+
+---
+
+## Configuration
+
+Config file location (in priority order):
+1. `--config` / `-c` flag
+2. `GITNOW_CONFIG` environment variable
+3. `~/.config/gitnow/gitnow.toml`
+
+### Config file format (TOML)
+
+```toml
+[settings]
+# Where repositories are cloned to (default: ~/git)
+projects = { directory = "~/git" }
+
+# Custom clone command (minijinja template)
+# Available variables: {{ ssh_url }}, {{ path }}
+# Default: "git clone {{ ssh_url }} {{ path }}"
+clone_command = "git clone {{ ssh_url }} {{ path }}"
+
+# Commands to run after cloning a repository
+post_clone_command = "echo 'cloned!'"
+# or as a list:
+# post_clone_command = ["cmd1", "cmd2"]
+
+# Commands to run when opening an already-cloned repository
+post_update_command = "git fetch --prune"
+
+[settings.cache]
+# Where the cache is stored (default: ~/.cache/gitnow)
+location = "~/.cache/gitnow"
+
+# Cache duration (default: 7 days). Set to false to disable.
+duration = { days = 7, hours = 0, minutes = 0 }
+
+[settings.worktree]
+# Custom worktree commands (minijinja templates)
+clone_command = "git clone --bare {{ ssh_url }} {{ bare_path }}"
+add_command = "git -C {{ bare_path }} worktree add {{ worktree_path }} {{ branch }}"
+list_branches_command = "git -C {{ bare_path }} branch -r --format=%(refname:short)"
+
+[settings.project]
+# Where scratch-pad projects are stored (default: ~/.gitnow/projects)
+directory = "~/.gitnow/projects"
+# Where project templates live (default: ~/.gitnow/templates)
+templates_directory = "~/.gitnow/templates"
+
+# --- Providers ---
+
+[[providers.github]]
+access_token = "ghp_..."           # or { env = "GITHUB_TOKEN" }
+current_user = "your-username"     # optional, for user-specific repos
+users = ["user1"]                  # fetch repos for these users
+organisations = ["org1", "org2"]   # fetch repos for these orgs
+url = "https://api.github.com"     # optional, for GitHub Enterprise
+
+[[providers.gitea]]
+url = "https://gitea.example.com/api/v1"
+access_token = "token"             # or { env = "GITEA_TOKEN" }
+current_user = "your-username"
+users = ["user1"]
+organisations = ["org1"]
+```
+
+Multiple provider entries are supported — gitnow aggregates repositories from all of them.
+
+## Typical workflows
+
+### First-time setup
+1. Create `~/.config/gitnow/gitnow.toml` with at least one provider
+2. Run `gitnow update` to populate the cache
+3. Run `gitnow` to interactively search and clone a repo
+
+### Daily use
+- `gitnow <partial-name>` — jump to a repo by fuzzy name
+- `gitnow worktree <repo> -b feature-x` — start work on a branch in a worktree
+- `gitnow project create my-feature` — set up a multi-repo workspace
+
+### Shell integration (zsh)
+Add to `.zshrc`:
+```zsh
+eval "$(gitnow init zsh)"
+```
+This wraps gitnow so that selecting a repository changes your current shell's
+working directory (instead of spawning a sub-shell).
