+# gulp-less-json-import
+
+This is a gulp preprocessor for the less compilation. It provide a directive **@json-import** to import variables 
+defined in a json file.
+
+It inject the Less formated data in place of the directive in the file buffer without write it on disk.
+
+## Exemple
+
+In less
+```Less
+@json-import "../relative/path.json";
+@json-import "../relative/path/extOmit";
+```
+
+In gulp
+```javascript
+var gulp = require('gulp');
+var less = require('gulp-less');
+var lessJsonImport = require('gulp-less-json-import');
+
+gulp.src(['./less/**/*.less', '!./less/**/_*.less'])
+    .pipe(lessJsonImport())
+    .pipe(less())
+    .pipe(gulp.dest('./css'));
+```
