-### Built with
+You can try the standalone editor at **http://juliandescottes.github.io/piskel** or see it integrated in **http://piskelapp.com**.
 
-The Piskel editor is purely built in **JavaScript, HTML and CSS**.
+Piskel is mainly developped by :
+
+* **[@juliandescottes](https://github.com/juliandescottes)**
+* **[@grosbouddha](https://github.com/grosbouddha)**
+
+## What's the point ?
+
+You can use Piskel to do two things :
+* **spriting** : create retro-style sprites for games
+
+![Megaman spritesheet](http://piskel-imgstore-a.appspot.com/img/c8081287-ac58-11e3-bd8c-b3c4036c0eee.png "Megaman spritesheet")
+
+* **pixelart** : create crazy/pretty pixelart animations for fun !
+
+![Rabbit jumping](http://piskel-imgstore-a.appspot.com/img/947f2dab-ac58-11e3-949a-b3c4036c0eee.gif "Rabit jumping")
+
+Integrated in **[piskelapp.com](http://piskelapp.com)**, you can share everything you work on with others as easily as you share a link.
+
+## Requirements
+
+Piskel supports the following browsers :
+* **Chrome** (latest)
+* **Firefox** (latest)
+* **Internet Explorer** 11+
+
+... and a fairly recent computer.
+
+We don't plan/want/could be forced into supporting older IEs. For Opera and Safari, we've never tested them but the gap shouldn't be huge.
+
+## Offline version
+
+Offline builds are available. More details in the [dedicated wiki page](https://github.com/juliandescottes/piskel/wiki/Desktop-applications).
+
+## Built with

-# Release instructions
-
-- retrieve source code and dependencies
-  - clone piskel `git clone https://github.com/piskelapp/piskel`
-  - clone piskel website `git clone https://github.com/piskelapp/piskel-website`
-  - download the appengine SDK for python at [this url](https://cloud.google.com/appengine/docs/standard/python/download). It seems recent versions don't work for me on Windows. [GoogleAppEngine-1.9.67.msi](https://storage.cloud.google.com/appengine-sdks/featured/GoogleAppEngine-1.9.67.msi?_ga=2.6838962.-1257793585.1543157659) looks ok...
-- prepare the release
-  - in `piskel-website` clone, checkout the `master` branch, not the `release`. The release branch is similar to the master branch, except it doesn't ignore the statics files coming from the `piskel` project. The idea is that we can easily checkout the release branch to do a new release, without having to rebuild piskel, in case nothing changed in piskel itself. We will switch to the release branch when we perform the final release.
-  - in `piskel` clone, create a new branch for the release `git checkout -b vX.Y`
-  - build and copy piskel to piskel-website (assumes the clones are in the same folder) `grunt && node bin/copy-to-piskel-website.js`
-- local test
-  - start piskel-website in the Google app engine launcher, test manually the update
-  - if any issue is detected create a commit to fix it (on the `vX.Y` branch) and push it.
-
-- beta test
-  - check the version in app.yaml is set to 'beta'. For historical reasons, alpha is the "production" version, while beta is the ... beta version. Don't ask.
-  - in the google app engine launcher, deploy this version.
-  - go to https://beta-dot-piskel-app.appspot.com and test (while this is not production frontend, it shares the same database, so be careful with what you create and delete)
-  - if any issue is detected create a commit to fix it (on `master`) and push it.
-- check caches...
-  - If any icon was modified or any script of piskel-website was modified, there's no nice way to clean the cache on each release... so we just put a time stamp in the requests. eg `background-image: url(../img/icons@2x.png?20181125);` or `<script type="text/javascript" src="/static/js/piskel-animated-preview.js?20181124"></script>`. Erk.
-- finalize the release
-  - in `piskel` update version in package.json. Remove the "-SNAPSHOT" at the end and commit the change, with a commit message such as `release: bump version to vX.Y`.
-  - in `piskel-website` checkout the `release` branch. Rebase it on master (that's pretty bad, we should probably cherry pick all the changes between the two branches...)
-  - once again build and copy piskel to piskel-website
-  - in `piskel-website` run `git status` to check that there are a bunch of changes to commit. (test locally again if you are paranoid)
-  - in `piskel-website` commit the current changes with a commit message such as `update statics for release vX.Y`
-  - Check that the version in app.yaml is now set to alpha. Deploy. Pray.
-- post release
-  - in piskel-website push the release branch to github
-  - in piskel add a last commit to update the version in package.json to update the version to `vX+1.0-SNAPSHOT`
-  - create a tag on github
