+### Plugin And Theme Bootstrap Compatibility
+
+Oh My Zsh now provides a shared bootstrap entrypoint at `lib/bootstrap.zsh` for plugin-manager setups that don't
+source `oh-my-zsh.sh`.
+
+When working on plugins/themes:
+
+- assume bootstrap has already run in manager-driven setups
+- rely on bootstrap guarantees (`ZSH*` defaults, cache/completions setup, required `fpath` entries)
+- avoid adding per-plugin/per-theme copies of common setup unless truly plugin-specific
+
+Common patterns we should migrate away from over time:
+
+- repeated cache setup logic (`mkdir -p "$ZSH_CACHE_DIR/completions"`)
+- repeated base `fpath` bootstrapping for OMZ core/custom directories
+
+If your plugin/theme still needs custom initialization, keep it scoped to that plugin/theme behavior only.

 If you would like to override the functionality of a plugin distributed with Oh My Zsh, create a plugin of the
 same name in the `custom/plugins/` directory and it will be loaded instead of the one in `plugins/`.
 
+### Using Plugin Managers Without `oh-my-zsh.sh`
+
+Some plugin managers load individual OMZ plugins/themes directly and do not source `oh-my-zsh.sh`.
+For those setups, source this bootstrap entrypoint before loading any OMZ plugin or theme:
+
+```zsh
+source "$ZSH/lib/bootstrap.zsh"
+```
+
+#### Bootstrap compatibility contract
+
+`lib/bootstrap.zsh` is idempotent and is the only required pre-load step for plugin-manager setups.
+It guarantees:
+
+- `ZSH`, `ZSH_CUSTOM`, and `ZSH_CACHE_DIR` defaults
+- writable cache fallback to `${XDG_CACHE_HOME:-$HOME/.cache}/oh-my-zsh`
+- `$ZSH_CACHE_DIR/completions` directory creation
+- required OMZ `fpath` entries for plugins/themes:
+  - `$ZSH/functions`
+  - `$ZSH/completions`
+  - `$ZSH_CUSTOM/functions`
+  - `$ZSH_CUSTOM/completions`
+  - `$ZSH_CACHE_DIR/completions`
+- public signal: `OMZ_IS_BOOTSTRAPPED=true` (for one-time hook guards)
+
+What still requires `oh-my-zsh.sh`:
+
+- update checks
+- plugin auto-discovery from the `plugins=(...)` list
+- `compinit`/`compfix` orchestration and zcompdump metadata refresh
+- alias filtering via `:omz:*` zstyles during file sourcing
+- final full-init signal: `OMZ_IS_LOADED=true`
+
+#### Plugin manager hook guidance
+
+Run bootstrap once, before any OMZ plugin/theme load:
+
+```zsh
+[[ -n "${OMZ_IS_BOOTSTRAPPED:-}" ]] || source "$ZSH/lib/bootstrap.zsh"
+```
+
+- **Antigen** (pre-bundle hook pattern):
+
+  ```zsh
+  omz_preload() { [[ -n "${OMZ_IS_BOOTSTRAPPED:-}" ]] || source "$ZSH/lib/bootstrap.zsh"; }
+  omz_preload
+  antigen bundle OMZ::plugins/git
+  antigen apply
+  ```
+
+- **Zinit** (`atinit` pre-load hook):
+
+  ```zsh
+  zinit ice atinit'[[ -n "${OMZ_IS_BOOTSTRAPPED:-}" ]] || source "$ZSH/lib/bootstrap.zsh"'
+  zinit snippet OMZ::plugins/git/git.plugin.zsh
+  ```
+
+- **zgen** (pre-load hook function called before OMZ loads):
+
+  ```zsh
+  omz_preload() { [[ -n "${OMZ_IS_BOOTSTRAPPED:-}" ]] || source "$ZSH/lib/bootstrap.zsh"; }
+  omz_preload
+  zgen load ohmyzsh/ohmyzsh plugins/git
+  ```
+
+- **zplug** (run pre-load hook immediately before OMZ entries):
+
+  ```zsh
+  omz_preload() { [[ -n "${OMZ_IS_BOOTSTRAPPED:-}" ]] || source "$ZSH/lib/bootstrap.zsh"; }
+  omz_preload
+  zplug "plugins/git", from:oh-my-zsh
+  zplug load
+  ```
+
+- **antibody** (run pre-load hook before `antibody bundle`/`source` output):
+
+  ```zsh
+  omz_preload() { [[ -n "${OMZ_IS_BOOTSTRAPPED:-}" ]] || source "$ZSH/lib/bootstrap.zsh"; }
+  omz_preload
+  source <(antibody bundle <<'EOF'
+  ohmyzsh/ohmyzsh path:plugins/git
+  EOF
+  )
+  ```
+
+- **zulu** (run pre-load hook before OMZ module loads):
+
+  ```zsh
+  omz_preload() { [[ -n "${OMZ_IS_BOOTSTRAPPED:-}" ]] || source "$ZSH/lib/bootstrap.zsh"; }
+  omz_preload
+  zulu install oh-my-zsh
+  ```
+
+Compatibility matrix:
+
+| Load mode | `OMZ_IS_BOOTSTRAPPED` | `OMZ_IS_LOADED` | Suitable for |
+| :-- | :--: | :--: | :-- |
+| `source $ZSH/oh-my-zsh.sh` | ✅ | ✅ | Full OMZ framework features |
+| `source $ZSH/lib/bootstrap.zsh` + manager-loaded OMZ plugins/themes | ✅ | ❌ | Plugin/theme prerequisites only |
+
+#### Manager entrypoints and OMZ-side auto-injection limits
+
+Most plugin managers load OMZ by directly sourcing selected plugin/theme/lib entrypoints, not by sourcing
+`oh-my-zsh.sh`, so OMZ cannot universally inject bootstrap on its own.
+
+| Manager | Typical OMZ entrypoint(s) it loads | Can OMZ auto-inject bootstrap without user hook? |
+| :-- | :-- | :--: |
+| Antigen | `antigen bundle ...` targets after `antigen use oh-my-zsh` | ❌ |
+| Zinit | `OMZ::`, `OMZL::`, `OMZP::`, `OMZT::` snippets | ❌ |
+| zgen | `zgen oh-my-zsh ...` selected OMZ paths | ❌ |
+| zplug | `from:oh-my-zsh` selected OMZ entries | ❌ |
+| antibody | `ohmyzsh/ohmyzsh path:...` selected OMZ paths | ❌ |
+| zulu | OMZ package/module entries selected by zulu | ❌ |
