+Hi, this is a [first-timers-only issue](https://code.publiclab.org/#r=all). This means we've worked to make it more legible to folks who either **haven't contributed to our codebase before, or even folks who haven't contributed to open source before**. 
+
+If that's you, we're interested in helping you take the first step and can answer questions and help you out as you do. Note that we're especially interested in contributions from people from groups underrepresented in free and open source software!
+
+We know that the process of creating a pull request is the biggest barrier for new contributors. This issue is for you 💝
+
+If you have contributed before, **consider leaving this one for someone new**, and looking through our general [help wanted](https://github.com/publiclab/image-sequencer/labels/help-wanted) issues. Thanks!
+
+### 🤔 What you will need to know.
+
+Nothing. This issue is meant to welcome you to Open Source :) We are happy to walk you through the process.
+
+### 📋 Step by Step
+
+- [ ] 🙋 **Claim this issue**: Comment below. If someone else has claimed it, ask if they've opened a pull request already and if they're stuck -- maybe you can help them solve a problem or move it along!
+
+- [ ] 📝 **Update** the file [$FILENAME]($BRANCH_URL) in the `$REPO` repository (press the little pen Icon) and edit the line as shown below. 
+
+[See this page](https://code.publiclab.org/#r=all) for some help in taking your first steps!

+
+$DIFF
+
+```
+- [ ] 💾 **Commit** your changes
+
+- [ ] 🔀 **Start a Pull Request**. There are two ways how you can start a pull request:
+
+1. If you are familiar with the terminal or would like to learn it, [here is a great tutorial](https://egghead.io/series/how-to-contribute-to-an-open-source-project-on-github) on how to send a pull request using the terminal.
+
+2. You can also [edit files directly in your browser](https://help.github.com/articles/editing-files-in-your-repository/) and open a pull request from there. 
+
+- [ ] 🏁 **Done** Ask in comments for a review :)
+
+### Please keep us updated
+
+💬⏰ - We encourage contributors to be respectful to the community and provide an update **within a week** of claiming a first-timers-only issue. We're happy to keep it assigned to you as long as you need if you update us with a request for more time or help, but if we don't see any activity a week after you claim it we may reassign it to give someone else a chance. Thank you in advance! 
+
+If this happens to you, don't sweat it! Grab another open issue.
+
+### Is someone else already working on this?
+
+🔗- We encourage contributors to link to the original issue in their pull request so all users can easily see if someone's already started on it. 
+
+👥- **If someone seems stuck, offer them some help!** Otherwise, [take a look at some other issues you can help with](https://code.publiclab.org/#r=all). Thanks!

+## Grunt Tasks
+This repository has different grunt tasks for different uses. The source code is in the [Gruntfile](https://github.com/publiclab/image-sequencer/blob/main/Gruntfile.js).
+
+The following command is used for running the tasks: `grunt [task-name]`. Here `[task-name]` should be replaced by the name of the task to be run. To run the default task run `grunt` without any options.
+
+#### Tasks
+1. **compile**: Compiles/Browserifies the dist files in `/dist/image-sequencer.js` and `/dist/image-sequencer-ui.js`.
+2. **build**: Compiles the files as in the **compile** task and minifies/uglifies dist files in `/dist/image-sequencer.min.js` and `/dist/image-sequencer-ui.min.js`.
+3. **watch**: Checks for any changes in the source code and runs the **compile** task if any changes are found.
+4. **serve**: Compiles the dist files as in the **compile** task and starts a local server on `localhost:3000` to host the demo site in `/examples/` directory. Also runs the **watch** task.
+5. **production**: Compiles and minifies dist files in `/dist/image-sequencer.js` and `/dist/image-sequencer-ui.js` without the `.min.js` extension to include minified files in the demo site. This script should only be used in production mode while deploying.
+6. **default**: Runs the **watch** task as default.
+
+## UI Helper Methods
+
+### scopeQuery
+
+###### Path: `/examples/lib/scopeQuery.js`
+
+The method returns a scoped `jQuery` object which only searches for elements inside a given scope (a DOM element).
+
+To use the method, 
+* import the `scopeSelector` and `scopeSelectorAll` methods from `lib/scopeQuery.js`
+* call the methods with scope as a parameter
+	
+```js
+var scopeQuery = require('./scopeQuery');
+
+var $step = scopeQuery.scopeSelector(scope),
+    $stepAll = scopeQuery.scopeSelectorAll(scope);	
+```
+This will return an object with a constructor which returns a `jQuery` object (from inside the scope) but with new `elem` and `elemAll` methods.
+
+#### Methods of the Returned Object
+* `elem()`: Selects an element inside the scope; 
+* `elemAll()`: Selects all the instances of a given element inside the scope;
+
+#### Example
+
+```js
+//The scope is a div element with id=“container“ and there are three divs in it 
+//with ids „1“, „2“, and „3“, and all of them have a „child“ class attribute
+
+var $step = require('./scopeQuery').scopeSelector(document.getElementById('container'));
+
+$step('#1'); // returns the div element with id=“1“
+$step('#1').hide().elemAll('.child').fadeOut(); // abruptly hides the div element with id=“1“ and fades out all other div elements
+```
+
+These two methods are chainable and will always return elements from inside the scope.
+
+#### Usage
+
+Instead of using
+
+```js
+$(step.ui.querySelector('query')).show().hide();
+$(step.ui.querySelectorAll('q2')).show().hide();
+```
+The following code can be used
+
+```js
+$step('query').show().hide();
+$stepAll('q2').show().hide();
+```

+## Importing steps using JSON array
+
+Image sequencer provides the following core API function to import the given sequence of JSON steps into sequencer.
+
+```js
+sequencer.importJSON(obj)
+```
+It can be implemented the following way for example:
+
+```js
+sequencer.importJSON([
+    { name: 'blur', options: {} }
+  ]);
+  ```
+  where name is the name of step to be added, options object can be the one used to provide various params to the sequencer which can customise the default ones.
+
+To see this in action, please refer to line # 51 of the following:

+[test/core/modules/import-export.js](https://github.com/publiclab/image-sequencer/blob/main/test/core/modules/import-export.js)
