+# Gignore - Generate .gitinore files
+
+## Install
+
+With [Task][task]:
+
+```bash
+task install
+```
+
+## Usage
+
+```bash
+Usage of gignore:
+  gignore [flags] <template>
+
+Flags:
+  -dir string
+        directory containing .gitignore templates (default "gitignoreio")
+  -list
+        list available templates
+  -ls
+        list available templates (shorthand)
+
+Example:
+  gignore go
+```
+
+## Custom Templates
+
+It's possible to add your own custom templates, simply create a directory in `internal/registry/templates`. You'll need to rebuild the project before you can load the new templates.
+
+Then pass the dir name as a flag, for example:
+
+```bash
+gignore -dir=custom go
+```
+
+You may set an environment variable `GIGNORE_TEMPLATE_DIR` to avoid passing the `-dir` flag each time.
+
+If a template is requested but not found in the custom directory then the gitignoreio registry will act as a fallback.
+
+## Special Thanks
+
+[gitignore.io][gitignoreio] For providing such a useful .gitignore service
+
+[gigo][gigo] For writing the Go client library for gitignore.io
