+# Usage
 
-# ngx-translate-extract
+## ngx-translate-extract
 Extract translatable (ngx-translate) strings and save as a JSON or Gettext pot file.
 Merges with existing strings if the output file already exists.
 
-## Usage
+### Usage
 Install the package in your project:
 
 `npm install @biesbjerg/ngx-translate-extract --save-dev`
 
-Add an `extract` script to your project's `package.json`:
-```
+Add a script to your project's `package.json`:
+```json
+...
 "scripts": {
-  "extract": "ngx-translate-extract --input ./src --output ./src/assets/i18n/ --clean --sort --format namespaced-json"
+  "extract-i18n": "ngx-translate-extract --input ./src --output ./src/assets/i18n/ --clean --sort --format namespaced-json"
 }
+...
 ```
-You can now run `npm run extract` to extract strings.
+You can now run `npm run extract-i18n` and it will extract strings from your project.
 
-## Extract examples
+### Examples
 
 **Extract from dir and save to file**
 
-`ngx-translate-extract -i ./src -o ./src/i18n/strings.json`
+`ngx-translate-extract --input ./src --output ./src/assets/i18n/template.json`
 
 **Extract from multiple dirs**
 
-`ngx-translate-extract -i ./src/folder-a ./src/folder-b -o ./src/i18n/strings.json`
+`ngx-translate-extract --input ./src-a ./src-b --output ./src/assets/i18n/template.json`
 
-**Extract and save to multiple files**
 
-`ngx-translate-extract -i ./src -o ./src/i18n/{da,en,fr}.json`
+**Extract and save to multiple files using path expansion**
 
-**or**
+_Note: This method does not work on Windows!_
 
-`ngx-translate-extract -i ./src -o ./src/i18n/da.json ./src/i18n/en.json ./src/i18n/fr.json`
+`ngx-translate-extract --input ./src --output ./src/i18n/{da,en}.json`
 
-**or (update only)**
+On Windows you must specify each output destination individually:
 
-`ngx-translate-extract -i ./src -o ./src/i18n/*.json`
+`ngx-translate-extract --input ./src --output ./src/i18n/da.json ./src/i18n/en.json`
 
-**or (update only)**
-
-## Custom indentation
-By default, tabs are used for indentation when writing extracted strings to json formats:
-
-`ngx-translate-extract -i ./src -o ./src/i18n/en.json --format-indentation $'\t'`
+### JSON indentation
+Tabs are used by default for indentation when saving extracted strings in json formats:
 
 If you want to use spaces instead, you can do the following:
 
-`ngx-translate-extract -i ./src -o ./src/i18n/en.json --format-indentation '  '`
+`ngx-translate-extract --input ./src --output ./src/i18n/en.json --format-indentation '  '`
 
 ## Mark strings for extraction using a marker function
-If, for some reason, you want to extract strings not passed directly to TranslateService, you can wrap them in a custom marker function.
+If, for some reason, you want to extract strings not passed directly to `TranslateService`'s `get()` or `instant()` methods, you can wrap them in a custom marker function to let `ngx-translate-extract` know you want to extract them.
+
+Install marker function:
+`npm install @biesbjerg/ngx-translate-extract-marker`
 
 ```ts
-import { _ } from '@biesbjerg/ngx-translate-extract';
+import { marker } from '@biesbjerg/ngx-translate-extract-marker';
 
-_('Extract me');
+marker('Extract me');
 ```
 
 Add the `marker` argument when running the extract script:
 
-`ngx-translate-extract ... -m _`
+`ngx-translate-extract ... -m extract`
 
-Modify the scripts arguments as required.
+You can alias the marker function if needed:
+
+```ts
+import { marker as _ } from '@biesbjerg/ngx-translate-extract-marker';
+
+_('Extract me');
+```
+
+`ngx-translate-extract ... -m _`
