+GNU LESSER GENERAL PUBLIC LICENSE
+Version 3, 29 June 2007
+
+Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+
+
+This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+0. Additional Definitions.
+
+As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+"The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+1. Exception to Section 3 of the GNU GPL.
+
+You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+2. Conveying Modified Versions.
+
+If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+a) under this License, provided that you make a good faith effort to
+ensure that, in the event an Application does not supply the
+function or data, the facility still operates, and performs
+whatever part of its purpose remains meaningful, or
+
+b) under the GNU GPL, with none of the additional permissions of
+this License applicable to that copy.
+
+3. Object Code Incorporating Material from Library Header Files.
+
+The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+a) Give prominent notice with each copy of the object code that the
+Library is used in it and that the Library and its use are
+covered by this License.
+
+b) Accompany the object code with a copy of the GNU GPL and this license
+document.
+
+4. Combined Works.
+
+You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+a) Give prominent notice with each copy of the Combined Work that
+the Library is used in it and that the Library and its use are
+covered by this License.
+
+b) Accompany the Combined Work with a copy of the GNU GPL and this license
+document.
+
+c) For a Combined Work that displays copyright notices during
+execution, include the copyright notice for the Library among
+these notices, as well as a reference directing the user to the
+copies of the GNU GPL and this license document.
+
+d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+e) Provide Installation Information, but only if you would otherwise
+be required to provide such information under section 6 of the
+GNU GPL, and only to the extent that such information is
+necessary to install and execute a modified version of the
+Combined Work produced by recombining or relinking the
+Application with a modified version of the Linked Version. (If
+you use option 4d0, the Installation Information must accompany
+the Minimal Corresponding Source and Corresponding Application
+Code. If you use option 4d1, you must provide the Installation
+Information in the manner specified by section 6 of the GNU GPL
+for conveying Corresponding Source.)
+
+5. Combined Libraries.
+
+You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+a) Accompany the combined library with a copy of the same work based
+on the Library, uncombined with any other library facilities,
+conveyed under the terms of this License.
+
+b) Give prominent notice with the combined library that part of it
+is a work based on the Library, and explaining where to find the
+accompanying uncombined form of the same work.
+
+6. Revised Versions of the GNU Lesser General Public License.
+
+The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+# ReFramed
+## Overview
+This Project is an unofficial port of [FramedBlocks](https://github.com/XFactHD/FramedBlocks) 
+forked from [Templates 2](https://github.com/quat1024/templates-mod). 
+It aims to add the same mechanics as [FramedBlocks](https://github.com/XFactHD/FramedBlocks) into Fabric.
+
+For a complete Feature list please have a look at the [Modrinth](https://modrinth.com/mod/reframed) page.
+
+## Information
+### Where to get it?
+The mod can be downloaded on [Modrinth](https://modrinth.com/mod/reframed).
+
+### Issues/requests
+Any issues/requests may be addressed on this repository in the [Issues](https://github.com/DriHut/ReFramed/issues) section.
+
+### Out of date?
+I will be adding new shapes as time passes, but I am currently not planing on keeping up with the newer versions of the game.
+That said this mod is under permissive licenses and make it easy for anyone to create their own fork. 
+If anyone in the future plans to do so, I will gladly either link it from here and the modrinth page,
+or based on preferences add the person(s) to the project
+
+### What Shapes are planed to be added
+Currently, the list of shapes to be added is pretty simple as the mod is still under development:
+- Wall
+- Fence
+- Pane
+- Button
+- Pressure Plate
+- Trapdoor
+- Door
+- Carpet
+- Post
+- Half Slab (maybe redundant with Layer)
+- Slabs Stair (a stair with one end being of a second theme, might be done in multiple blocks)
+
+Any Ideas feel free to make a suggestion [here](https://github.com/DriHut/ReFramed/issues).
+
+## License
+This work is dual-licensed under MIT and LGPL 3.0 both applying to different part of this project:
+- The LGPL 3.0 license applies to all the textures that can be found in [`assets/reframed/textures`](src/main/resources/assets/reframed/textures)
+- The MIT license applied to everything else so including all the code present within this project

+`SPDX-License-Identifier: MIT AND LGPL-3.0`
