+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 `$REPO` repository (press the little pen Icon) and edit the line as shown below. 
+
+[See this page](https://code.publiclab.org/#r=all) for some help in taking your first steps!
+
+Below is a "diff" showing in red (and a `-`) which lines to remove, and in green (and a `+`) which lines to add:
+
+```diff
+
+$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!

+## User Preferences
+The user preferences API can be used for adding, reading, updating and deleting user preferences in the browser using **indexedDB** API.
+* File Path: [/src/ui/userPrefs.js](https://github.com/publiclab/image-sequencer/blob/main/src/ui/userPrefs.js)
+### Usage
+```js
+var userPrefs = require('/path/to/userPrefs')(options);
+if (userPrefs.error) {
+  console.log(error);
+  return;
+}
+
+userPrefs.addPref('user-name', {name: 'user'}, () => {

+    console.log(pref.name); // user
+    userPrefs.new().deletePref('user-name', () => {console.log('deleted')}) // preference deleted
+    
+  })
+})
+```
+### Return Value
+A new `userPreferenceManager` object is returned by the function.
+###### note: If an error occured or if **indexedDB** is not supported by he browser, the return value will be an object with a string `error` property.
+#### Properties
+The `userPreferenceManager` object has the following properties.
+- `dbName`: Name of the database the user preferences are stored in.
+- `storeName`: The object store in the database where the user preferences are stored.
+#### Options
+The function accepts a single object called `options` as an argument which has the following properties.
+* `dbName`: Name of a custom database. Default is `user-prefs`.
+* `storeName`: Name of a custom objectStore. Default is `user-prefs`.
+#### Methods
+The following methods are available on the returned object.
+* `addPref(prefName, preference, callback)`: Adds a preference with the name `prefName` and value `preference`. `preference` is an object containing any key but `preference`. `callback` is a function executed once a preference as been added.
+* `deletePref(prefName, callback)`: Deletes he preference with the name `prefName` if it exists. `callback` is executed once the preference is deleted.
+* `updatePref(prefName, preference, callback)`: Updates the value of the preference with the name `prefName` to `preference`.
+* `getPref(prefName, callback)`: Gets the preference with the name `prefName`. The value is passed to `callback` which is executed once the preference is fetched. If the requested preference doesn't exist then the value passed to `callback` will be `undefined`.
+* `new()`: Returns a new `userPreferenceManager` object with the same options as before. This function can be used if the original object is to be reused as the `userPreferenceManager` object can only be used once.
+
+
+
+## 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();
+```

 This method returns an object which defines the name and inputs of the modules. If a module name (hyphenated) is passed in the method, then only the details of that module are returned.
 
 The `notify` function takes two parameters `msg` and `id`, former being the message to be displayed on console (in case of CLI and node ) and a HTML component(in browser). The id is optional and is useful for HTML interface to give appropriate IDs.
+
+## Using WebAssembly for heavy pixel processing
+
+Any module which uses the `changePixel` function gets WebAssembly acceleration (`wasm`). Both node and browser code use WebAssembly and the only code which falls back to non-`wasm` code is the [browserified unit tests](https://github.com/publiclab/image-sequencer/blob/main/test/core/sequencer/benchmark.js).
+
+The main advantage we get using `wasm` is blazing fast speed attained in processing pixels for many modules that is very clear from [checking module benchmarks](https://travis-ci.org/publiclab/image-sequencer/jobs/544415673#L1931).
+
+
+The only limitation is that browser and node code for `wasm` had to be written separately, and switched between. This is because in browser we use `fetch` to retrieve the compiled `wasm` program while in node we use the `fs` module, each of which cannot be used in the other's environment.
+
+
+`wasm` mode is enabled by default. If you need to force this mode to be on or off, you can use the `useWasm` option when initializing ImageSequencer:
+
+```js
+let sequencer = ImageSequencer({useWasm:true}) // for wasm mode or simply
+
+let sequencer = ImageSequencer() // also for wasm mode i.e. default mode
+
+let sequencer = ImageSequencer({useWasm:false}) //for non-wasm mode 
+
+```
