+# Fragment Search Paths
+
+TypeDialog supports loading form fragments from multiple directories using the `TYPEDIALOG_FRAGMENT_PATH` environment variable.
+
+## Overview
+
+**Fragment search paths** enable:
+
+- ✅ Centralized fragment libraries shared across projects
+- ✅ Local overrides for project-specific customizations
+- ✅ Zero duplication when using standard fragments
+- ✅ Automatic updates when central library is updated
+
+## Environment Variable
+
+### TYPEDIALOG_FRAGMENT_PATH
+
+Colon-separated list (semicolon on Windows) of directories to search for fragment files.
+
+**Unix/Linux/macOS:**
+
+```bash
+export TYPEDIALOG_FRAGMENT_PATH="/path/to/fragments:/another/path"
+```
+
+**Windows:**
+
+```cmd
+set TYPEDIALOG_FRAGMENT_PATH=C:\fragments;D:\other\fragments
+```
+
+## Search Order
+
+When a fragment is referenced (e.g., `includes = ["fragments/user-fields.toml"]`), TypeDialog searches in this order:
+
+1. **Absolute path** → Use directly if provided
+2. **Form's directory** (`base_dir`) → Backward compatible behavior
+3. **Directories in TYPEDIALOG_FRAGMENT_PATH** → Search left to right
+4. **First match wins** → Subsequent directories are not checked
+
+### Example
+
+```bash
+export TYPEDIALOG_FRAGMENT_PATH=".typedialog/ci/fragments:/usr/local/share/typedialog/fragments"
+```
+
+**Fragment reference:** `includes = ["user-auth.toml"]`
+
+**Search order:**
+
+```text
+1. ./user-auth.toml (form's directory)
+2. .typedialog/ci/fragments/user-auth.toml (local)
+3. /usr/local/share/typedialog/fragments/user-auth.toml (system)
+```
+
+**Result:** First existing file is loaded.
+
+## Use Cases
+
+### Case 1: Centralized Fragment Library
+
+Organization maintains a shared library of standard fragments.
+
+**Setup:**
+
+```bash
+# System-wide fragments
+export TYPEDIALOG_FRAGMENT_PATH="/opt/company/typedialog/fragments"
+```
+
+**Directory structure:**
+
+```text
+/opt/company/typedialog/fragments/
+├── user-auth.toml
+├── database-config.toml
+├── api-settings.toml
+└── logging.toml
+```
+
+**Form reference:**
+
+```toml
+[[item]]
+type = "group"
+includes = ["user-auth.toml", "database-config.toml"]
+```
+
+**Benefit:** All projects use same fragments → consistency across organization.
+
+### Case 2: Local Overrides
+
+Project needs custom version of standard fragment.
+
+**Setup:**
+
+```bash
+export TYPEDIALOG_FRAGMENT_PATH=".typedialog/fragments:/opt/company/typedialog/fragments"
+```
+
+**Directory structure:**
+
+```text
+project/
+├── .typedialog/
+│   └── fragments/
+│       └── user-auth.toml  # ← Custom version
+└── form.toml
+```
+
+**Form reference:**
+
+```toml
+[[item]]
+type = "group"
+includes = ["user-auth.toml"]  # Uses local version
+```
+
+**Result:**
+
+- `user-auth.toml` → loads from `.typedialog/fragments/` (local override)
+- `database-config.toml` → loads from `/opt/company/...` (standard)
+
+**Benefit:** Override only what you need, rest stays synchronized.
+
+### Case 3: Multiple Fragment Sources
+
+Combine fragments from different sources: company library, team library, local.
+
+**Setup:**
+
+```bash
+export TYPEDIALOG_FRAGMENT_PATH=".typedialog/fragments:~/team-fragments:/opt/company/fragments"
+```
+
+**Search priority:**
+
+1. Project-specific (`.typedialog/fragments/`)
+2. Team-shared (`~/team-fragments/`)
+3. Company-wide (`/opt/company/fragments/`)
+
+**Benefit:** Flexible hierarchy for different scopes.
+
+## Configuration
+
+### direnv Integration
+
+Automatically load `TYPEDIALOG_FRAGMENT_PATH` when entering project directory.
+
+**Setup:**
+
+```bash
+# Install direnv
+brew install direnv  # macOS
+# Or: apt install direnv  # Linux
+
+# Add to shell rc file (~/.bashrc, ~/.zshrc)
+eval "$(direnv hook bash)"  # or zsh, fish, etc.
+
+# Create .envrc in project root
+cat > .envrc <<EOF
+export TYPEDIALOG_FRAGMENT_PATH=".typedialog/fragments:\$HOME/typedialog/fragments"
+EOF
+
+# Allow direnv to load .envrc
+direnv allow
+```
+
+**Result:** `TYPEDIALOG_FRAGMENT_PATH` is automatically set when you `cd` into project.
+
+### Shell Profile
+
+Set globally for all projects.
+
+**~/.bashrc or ~/.zshrc:**
+
+```bash
+export TYPEDIALOG_FRAGMENT_PATH="$HOME/.typedialog/fragments:/usr/local/share/typedialog/fragments"
+```
+
+### Per-Command
+
+Override for single invocation.
+
+```bash

+```
+
+## Implementation Details
+
+### Code Location
+
+`crates/typedialog-core/src/form_parser/parser.rs`
+
+**Functions:**
+
+- `get_fragment_search_paths()` - Parse environment variable
+- `resolve_fragment_path()` - Search directories in order
+
+**Logic:**
+
+```rust
+fn resolve_fragment_path(path: &str, base_dir: &Path) -> PathBuf {
+    // 1. Absolute path → use directly
+    if Path::new(path).is_absolute() {
+        return PathBuf::from(path);
+    }
+
+    // 2. Try base_dir (backward compatible)
+    let base_path = base_dir.join(path);
+    if base_path.exists() {
+        return base_path;
+    }
+
+    // 3. Try each search path
+    for search_dir in get_fragment_search_paths() {
+        let candidate = search_dir.join(path);
+        if candidate.exists() {
+            return candidate;
+        }
+    }
+
+    // 4. Return base_path for error reporting
+    base_path
+}
+```
+
+### Separator Detection
+
+**Unix/Linux/macOS:** `:` (colon)
+
+```rust
+#[cfg(unix)]
+let separator = ':';
+```
+
+**Windows:** `;` (semicolon)
+
+```rust
+#[cfg(windows)]
+let separator = ';';
+```
+
+### Backward Compatibility
+
+- ✅ If `TYPEDIALOG_FRAGMENT_PATH` not set → works as before (uses `base_dir`)
+- ✅ Absolute paths → always work regardless of search paths
+- ✅ Existing forms → no changes required
+
+## Best Practices
+
+### ✅ DO
+
+- **Use relative paths** in form definitions (`includes = ["fragment.toml"]`)
+- **Put local overrides first** in search path (`.typedialog/fragments:/system/fragments`)
+- **Document custom fragments** with comments explaining why local version exists
+- **Keep standard structure** when overriding (match original fragment structure)
+- **Version control .envrc** if project-specific paths are important
+
+### ❌ DON'T
+
+- **Don't hardcode absolute paths** in forms (defeats portability)
+- **Don't mix path separators** (use `:` on Unix, `;` on Windows)
+- **Don't create deep hierarchies** (2-3 levels max: local, team, system)
+- **Don't override without reason** (consider if change should be upstream)
+
+## Troubleshooting
+
+### Fragment not found
+
+**Error:**
+
+```text
+Error: Failed to load fragment 'user-fields.toml': No such file or directory
+```
+
+**Check:**
+
+```bash
+# 1. Verify environment variable is set
+echo $TYPEDIALOG_FRAGMENT_PATH
+
+# 2. Check if file exists in any search path
+ls .typedialog/fragments/user-fields.toml
+ls /usr/local/share/typedialog/fragments/user-fields.toml
+
+# 3. Check search order (add debug output)
+export TYPEDIALOG_DEBUG=1  # If supported
+```
+
+### Wrong version loaded
+
+**Symptom:** Expected local override, but system version is used.
+
+**Check search order:**
+
+```bash
+# Verify local path is FIRST
+echo $TYPEDIALOG_FRAGMENT_PATH
+# Should be: .typedialog/fragments:...
+
+# Verify local file exists
+ls -la .typedialog/fragments/fragment.toml
+```
+
+### Windows path issues
+
+**Problem:** Paths with spaces or special characters.
+
+**Solution:** Use quotes in environment variable:
+
+```cmd
+set TYPEDIALOG_FRAGMENT_PATH="C:\Program Files\TypeDialog\fragments;D:\Custom Fragments"
+```
+
+## Examples
+
+### Example 1: Standard Setup
+
+**Project structure:**
+
+```text
+project/
+├── form.toml
+├── .envrc
+└── .typedialog/
+    └── fragments/
+        └── custom-field.toml
+```
+
+**.envrc:**
+
+```bash
+export TYPEDIALOG_FRAGMENT_PATH=".typedialog/fragments:/usr/local/share/typedialog/fragments"
+```
+
+**form.toml:**
+
+```toml
+[[item]]
+type = "group"
+includes = [
+    "custom-field.toml",     # Loads from .typedialog/fragments/
+    "standard-fields.toml"   # Loads from /usr/local/share/.../
+]
+```
+
+### Example 2: Multi-Environment
+
+**Development:**
+
+```bash
+export TYPEDIALOG_FRAGMENT_PATH=".typedialog/fragments:$HOME/dev-fragments:/opt/fragments"
+```
+
+**Production:**
+
+```bash
+export TYPEDIALOG_FRAGMENT_PATH="/opt/company/fragments"
+```
+
+**Result:** Development has local overrides, production uses only approved fragments.
