+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.

+- [ ] 💾 **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!

@@ -44,6 +44,7 @@ __Moderators Group:__ The moderators group is responsible for addressing immedia
 We begin interactions by acknowledging that we are part of a community with complementary goals. Different views are allowed to respectfully coexist in the same space. When something's happened and someone is uncomfortable, our first choice is to work through it. Endeavor to listen and appropriately adjust your behavior if someone approaches you privately with a request that you apologize or publicly requests that you stop an ongoing presentation. If someone questions your words, actions or motives, or "calls you out", hear their feedback and respond respectfully. It’s okay to not understand why something is hurtful or causes discomfort, as long as you approach it respectfully, with empathy. Repeating hurtful behavior after it has been addressed is disrespectful and is not allowed. Doing so will result in removal and subsequent banning from in-person events and being placed into moderation in online spaces. 
 
 ### The first rule of engaging with others is consent
+
 During in-person gatherings, consent is important to highlight because the negotiation of consent can be subtle, and it’s easy to miss each other’s non-verbal cues, resulting in miscommunication and/or offense. During online interactions, consent can be even harder to distinguish.
 
 We make guesses or assessments of consent (willingness, welcome, invitation) all the time. Then we stay open to signs that the consent isn't there. Handshakes are a clear example of consent: someone offers a hand, and you take it if you want to shake it. A friendly smile might indicate consent to start a conversation. It might not. We learn that in the interaction. Sometimes we ask directly. We are open to making mistakes, and learning from them. The more we learn to be empathetic and see other people, the more we're able to talk about consent.

+
+## Linting
+
+We are now using `eslint` and `husky` to help lint and format our code each time we commit. Eslint defines coding standards and helps in cleaning up the code. To run eslint for checking errors globally or within a specific file run:
+
+```
+npx eslint . 
+
+npx eslint <file path>
+```
+And to fix those errors globally or in a file, run these in your terminal:
+```
+npx eslint . --fix
+
+npx eslint <file path> --fix
+```
+Be sure to not include the angular brackets(<>).
+
+Husky ensures automation of the above steps with git-hooks(eg. git add,git commit..). However we don't want to check and fix changes of the entire codebase with each commit and that the fixes made by eslint appear unstaged and require us to commit them  again and that is where lint-staged helps.
+
+If we want `husky` to not verify the commit and push it anyway, use `git commit -m "message" --no-verify.`
+
+## 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();
 ```
-The length is absolutely required for a meta-module, since sequencer is optimized to re-run minimum number of steps when a step is added in the UI which is 1 in the case of normal modules, if the added step is a meta-module the length of the sequence governs the number of steps to re-run.

+Image Sequencer is different from other image processing systems because it's _non-destructive_: instead of modifying the original image, it **creates a new image at each step in a sequence**. This is because it:
 
 * produces a legible trail of operations, to "show your work" for evidential, educational, or reproducibility reasons
 * makes the creation of new tools or "modules" simpler -- each must accept an input image, and produce an output image
