Files related with building distribution images now have it's own
directory. Files for development using docker-compose are now placed in

+
+Adapted from http://www.apache.org/licenses/icla.txt © The Apache Software Foundation
+
+Thank you for your interest in Co Jedzie (the **"Project"**) by Kacper Donat (the **"Author"**). In order to clarify the
+intellectual property license granted with Contributions from any person or entity, the Author must have a Contributor
+License Agreement ("CLA") on file that has been signed by each Contributor, indicating agreement to the license terms
+below. This license is for your protection as a Contributor as well as the protection of the Author and its users; it
+does not change your rights to use your own Contributions for any other purpose.
+
+You accept and agree to the following terms and conditions for Your present and future Contributions submitted to the
+Author. In return, the Author shall not use Your Contributions in a way that is contrary to the public benefit or
+inconsistent with its bylaws in effect at the time of the Contribution. Except for the license granted herein to the
+Author and recipients of software distributed by the Author, You reserve all right, title, and interest in and to Your
+Contributions.
+
+1. Definitions.
+    - **"You"** (or **"Your"**) shall mean the copyright owner or legal entity authorized by the copyright owner that is
+      making this Agreement with the Author. For legal entities, the entity making a Contribution and all other entities
+      that control, are controlled by, or are under common control with that entity are considered to be a single
+      Contributor. For the purposes of this definition, **"control"** means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty percent (50%) or
+      more of the outstanding shares, or (iii) beneficial ownership of such entity.
+
+    - **"Contribution"** shall mean any original work of authorship, including any modifications or additions to an existing
+      work, that is intentionally submitted by You to the Author for inclusion in, or documentation of, any of the products
+      owned or managed by the Author (the **"Work"**). For the purposes of this definition, **"submitted"** means any form
+      of electronic, verbal, or written communication sent to the Author or its representatives, including but not limited
+      to communication on electronic mailing lists, source code control systems, and issue tracking systems that are managed
+      by, or on behalf of, the Author for the purpose of discussing and improving the Work, but excluding communication that
+      is conspicuously marked or otherwise designated in writing by You as **"Not a Contribution."**
+
+2. Grant of Copyright License. Subject to the terms and conditions of this Agreement, You hereby grant to the Author and
+   to recipients of software distributed by the Author a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
+   irrevocable copyright license to reproduce, prepare derivative works of, publicly display, publicly perform,
+   sublicense, re-license, and distribute Your Contributions and such derivative works.
+
+3. Grant of Patent License. Subject to the terms and conditions of this Agreement, You hereby grant to the Author and to
+   recipients of software distributed by the Author a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
+   irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import,
+   and otherwise transfer the Work, where such license applies only to those patent claims licensable by You that are
+   necessarily infringed by Your Contribution(s) alone or by combination of Your Contribution(s) with the Work to which
+   such Contribution(s) was submitted. If any entity institutes patent litigation against You or any other entity (
+   including a cross-claim or counterclaim in a lawsuit) alleging that your Contribution, or the Work to which you have
+   contributed, constitutes direct or contributory patent infringement, then any patent licenses granted to that entity
+   under this Agreement for that Contribution or Work shall terminate as of the date such litigation is filed.
+
+4. You represent that you are legally entitled to grant the above license. If your employer(s) has rights to
+   intellectual property that you create that includes your Contributions, you represent that you have received
+   permission to make Contributions on behalf of that employer, that your employer has waived such rights for your
+   Contributions to the Author, or that your employer has executed a separate Corporate CLA with the Author.
+
+5. You represent that each of Your Contributions is Your original creation (see section 7 for submissions on behalf of
+   others). You represent that Your Contribution submissions include complete details of any third-party license or
+   other restriction (including, but not limited to, related patents and trademarks) of which you are personally aware
+   and which are associated with any part of Your Contributions.
+
+6. You are not expected to provide support for Your Contributions, except to the extent You desire to provide support.
+   You may provide support for free, for a fee, or not at all. Unless required by applicable law or agreed to in
+   writing, You provide Your Contributions on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either
+   express or implied, including, without limitation, any warranties or conditions of TITLE, NON- INFRINGEMENT,
+   MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.
+
+7. Should You wish to submit work that is not Your original creation, You may submit it to the Author separately from
+   any Contribution, identifying the complete details of its source and of any license or other restriction (including,
+   but not limited to, related patents, trademarks, and license agreements) of which you are personally aware, and
+   conspicuously marking the work as "Submitted on behalf of a third-party: [named here]".
+
+8. You agree to notify the Author of any facts or circumstances of which you become aware that would make these
+   representations inaccurate in any respect.

+# How to contribute?
+
+Thanks for your interest in the project!
+
+## I'd like to propose some feature / change...
+
+Cool! Go ahead, [create an issue] and describe your proposal so anyone can see it. You can also vote on features that
+you want the most.
+
+## I've found a bug!
+
+Well, less cool! Before creating an issue, please check if the bug remains after hard refreshing (usually `ctrl+F5`) the
+application. If the answer is yes, or this is not the first encounter of it please [create an issue] and describe the
+problem. If you can, please attach screenshots (especially if this is visual bug), and console logs (especially for
+connection problems) - this will help to reproduce the problem.
+
+## I've got some spare resources on my server...
+Soon you will be able to help the project by hosting your own API node that will be available for clients to use. 
+More details to come soon.
+
+## I want to contribute some code...
+
+That's great! If you want to make changes to API (which is responsible for collecting and supplying applicaiton with 
+data) please check the [API contribution guidelines], if you are interested in UI side of the app please read the 
+[frontend contribution guidelines].
+
+### Contributor License Agreement
+
+Unfortunately due to this project nature and license I need you to sign [Contributor License Agreement] - the nice thing
+is that it can be done with simple push of a button! **You still will have full copyright to your contribution** but
+basically you consent that you are entitled to code you are submitting and also to allow me to license this project on
+other terms if needed to, for example, local governments. If you don't want to sign - I understand - but I won't be able
+to accept your contribution :(
