+<h1>ASSIMP - Frequently Asked Questions (FAQ)</h2>
+
+<h4>Can I use the library for a commercial product?</h4>
+Yes. ASSIMP is licensed under a modified BSD license. Its contents in just one sentence: you may use the library for free, in commercial or non-commercial applications, but you must include our license with your product and you may not advertise with us.
+
+<h4>Is ASSIMP able to export assets?</h4>
+No. ASSIMP is an <b>import</b> library. It is intended to be used to import assets exported from programs like 3ds max into game engines. Normally you won't need to export the assets again.
+
+
+<h4>For which languages is the API provided?</h4>
+The ASSIMP API is provided both as a plain-C interface and as an object-oriented C++ interface, which is the main API. All ports (jAssimp, Assimp.net, ...) and even the C-style API are just wrappers around this interface. Therefore, if your project allows the use of C++, you should use the C++-API.
+
+
+<h4>Is the library thread-safe?</h4>
+Yes. ASSIMP is completely thread-safe, as long as you create an extra 'Importer' instance for each thread. The C-API and all ports are doing this automatically for you.
+
+<h4>Who are you (the guys behind ASSIMP)?</h4>
+Most of use are professional software developers from Germany, but not in GameDev business. Graphics/game programming is a hobby for all of us.
+
+<h4>Can I write a new loader for the library?</h4>
+Sure, as long as you're able to write stable code and the format is not too exotic ... We'd highly appreciate any help. When you're finished, contact us and we're going to test it. If it works well, it will be included with the next release of the library.
+
+<h4>I love you. May I marry all of you?</h4>
+We're sorry, but this is absolutely not possible.

+*Attribution 2.5*
+
+CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+LEGAL SERVICES. DISTRIBUTION OF THIS LICENSE DOES NOT CREATE AN
+ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS INFORMATION
+ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES REGARDING THE
+INFORMATION PROVIDED, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+ITS USE.
+
+/License/
+
+THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
+COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
+COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
+AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
+
+BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE
+TO BE BOUND BY THE TERMS OF THIS LICENSE. THE LICENSOR GRANTS YOU THE
+RIGHTS CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS
+AND CONDITIONS.
+
+*1. Definitions*
+
+   1. *"Collective Work"* means a work, such as a periodical issue,
+      anthology or encyclopedia, in which the Work in its entirety in
+      unmodified form, along with a number of other contributions,
+      constituting separate and independent works in themselves, are
+      assembled into a collective whole. A work that constitutes a
+      Collective Work will not be considered a Derivative Work (as
+      defined below) for the purposes of this License.
+   2. *"Derivative Work"* means a work based upon the Work or upon the
+      Work and other pre-existing works, such as a translation, musical
+      arrangement, dramatization, fictionalization, motion picture
+      version, sound recording, art reproduction, abridgment,
+      condensation, or any other form in which the Work may be recast,
+      transformed, or adapted, except that a work that constitutes a
+      Collective Work will not be considered a Derivative Work for the
+      purpose of this License. For the avoidance of doubt, where the
+      Work is a musical composition or sound recording, the
+      synchronization of the Work in timed-relation with a moving image
+      ("synching") will be considered a Derivative Work for the purpose
+      of this License.
+   3. *"Licensor"* means the individual or entity that offers the Work
+      under the terms of this License.
+   4. *"Original Author"* means the individual or entity who created the
+      Work.
+   5. *"Work"* means the copyrightable work of authorship offered under
+      the terms of this License.
+   6. *"You"* means an individual or entity exercising rights under this
+      License who has not previously violated the terms of this License
+      with respect to the Work, or who has received express permission
+      from the Licensor to exercise rights under this License despite a
+      previous violation.
+
+*2. Fair Use Rights.* Nothing in this license is intended to reduce,
+limit, or restrict any rights arising from fair use, first sale or other
+limitations on the exclusive rights of the copyright owner under
+copyright law or other applicable laws.
+
+*3. License Grant.* Subject to the terms and conditions of this License,
+Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
+perpetual (for the duration of the applicable copyright) license to
+exercise the rights in the Work as stated below:
+
+   1. to reproduce the Work, to incorporate the Work into one or more
+      Collective Works, and to reproduce the Work as incorporated in the
+      Collective Works;
+   2. to create and reproduce Derivative Works;
+   3. to distribute copies or phonorecords of, display publicly, perform
+      publicly, and perform publicly by means of a digital audio
+      transmission the Work including as incorporated in Collective Works;
+   4. to distribute copies or phonorecords of, display publicly, perform
+      publicly, and perform publicly by means of a digital audio
+      transmission Derivative Works.
+   5.
+
+      For the avoidance of doubt, where the work is a musical composition:
+
+         1. *Performance Royalties Under Blanket Licenses*. Licensor
+            waives the exclusive right to collect, whether individually
+            or via a performance rights society (e.g. ASCAP, BMI,
+            SESAC), royalties for the public performance or public
+            digital performance (e.g. webcast) of the Work.
+         2. *Mechanical Rights and Statutory Royalties*. Licensor waives
+            the exclusive right to collect, whether individually or via
+            a music rights agency or designated agent (e.g. Harry Fox
+            Agency), royalties for any phonorecord You create from the
+            Work ("cover version") and distribute, subject to the
+            compulsory license created by 17 USC Section 115 of the US
+            Copyright Act (or the equivalent in other jurisdictions).
+   6. *Webcasting Rights and Statutory Royalties*. For the avoidance of
+      doubt, where the Work is a sound recording, Licensor waives the
+      exclusive right to collect, whether individually or via a
+      performance-rights society (e.g. SoundExchange), royalties for the
+      public digital performance (e.g. webcast) of the Work, subject to
+      the compulsory license created by 17 USC Section 114 of the US
+      Copyright Act (or the equivalent in other jurisdictions).
+
+The above rights may be exercised in all media and formats whether now
+known or hereafter devised. The above rights include the right to make
+such modifications as are technically necessary to exercise the rights
+in other media and formats. All rights not expressly granted by Licensor
+are hereby reserved.
+
+*4. Restrictions.*The license granted in Section 3 above is expressly
+made subject to and limited by the following restrictions:
+
+   1. You may distribute, publicly display, publicly perform, or
+      publicly digitally perform the Work only under the terms of this
+      License, and You must include a copy of, or the Uniform Resource
+      Identifier for, this License with every copy or phonorecord of the
+      Work You distribute, publicly display, publicly perform, or
+      publicly digitally perform. You may not offer or impose any terms
+      on the Work that alter or restrict the terms of this License or
+      the recipients' exercise of the rights granted hereunder. You may
+      not sublicense the Work. You must keep intact all notices that
+      refer to this License and to the disclaimer of warranties. You may
+      not distribute, publicly display, publicly perform, or publicly
+      digitally perform the Work with any technological measures that
+      control access or use of the Work in a manner inconsistent with
+      the terms of this License Agreement. The above applies to the Work
+      as incorporated in a Collective Work, but this does not require
+      the Collective Work apart from the Work itself to be made subject
+      to the terms of this License. If You create a Collective Work,
+      upon notice from any Licensor You must, to the extent practicable,
+      remove from the Collective Work any credit as required by clause
+      4(b), as requested. If You create a Derivative Work, upon notice
+      from any Licensor You must, to the extent practicable, remove from
+      the Derivative Work any credit as required by clause 4(b), as
+      requested.
+   2. If you distribute, publicly display, publicly perform, or publicly
+      digitally perform the Work or any Derivative Works or Collective
+      Works, You must keep intact all copyright notices for the Work and
+      provide, reasonable to the medium or means You are utilizing: (i)
+      the name of the Original Author (or pseudonym, if applicable) if
+      supplied, and/or (ii) if the Original Author and/or Licensor
+      designate another party or parties (e.g. a sponsor institute,
+      publishing entity, journal) for attribution in Licensor's
+      copyright notice, terms of service or by other reasonable means,
+      the name of such party or parties; the title of the Work if
+      supplied; to the extent reasonably practicable, the Uniform
+      Resource Identifier, if any, that Licensor specifies to be
+      associated with the Work, unless such URI does not refer to the
+      copyright notice or licensing information for the Work; and in the
+      case of a Derivative Work, a credit identifying the use of the
+      Work in the Derivative Work (e.g., "French translation of the Work
+      by Original Author," or "Screenplay based on original Work by
+      Original Author"). Such credit may be implemented in any
+      reasonable manner; provided, however, that in the case of a
+      Derivative Work or Collective Work, at a minimum such credit will
+      appear where any other comparable authorship credit appears and in
+      a manner at least as prominent as such other comparable authorship
+      credit.
+
+*5. Representations, Warranties and Disclaimer*
+
+UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
+OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
+KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
+INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
+FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
+LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
+WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE
+EXCLUSION OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
+
+*6. Limitation on Liability.* EXCEPT TO THE EXTENT REQUIRED BY
+APPLICABLE LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL
+THEORY FOR ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY
+DAMAGES ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF
+LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+*7. Termination*
+
+   1. This License and the rights granted hereunder will terminate
+      automatically upon any breach by You of the terms of this License.
+      Individuals or entities who have received Derivative Works or
+      Collective Works from You under this License, however, will not
+      have their licenses terminated provided such individuals or
+      entities remain in full compliance with those licenses. Sections
+      1, 2, 5, 6, 7, and 8 will survive any termination of this License.
+   2. Subject to the above terms and conditions, the license granted
+      here is perpetual (for the duration of the applicable copyright in
+      the Work). Notwithstanding the above, Licensor reserves the right
+      to release the Work under different license terms or to stop
+      distributing the Work at any time; provided, however that any such
+      election will not serve to withdraw this License (or any other
+      license that has been, or is required to be, granted under the
+      terms of this License), and this License will continue in full
+      force and effect unless terminated as stated above.
+
+*8. Miscellaneous*
+
+   1. Each time You distribute or publicly digitally perform the Work or
+      a Collective Work, the Licensor offers to the recipient a license
+      to the Work on the same terms and conditions as the license
+      granted to You under this License.
+   2. Each time You distribute or publicly digitally perform a
+      Derivative Work, Licensor offers to the recipient a license to the
+      original Work on the same terms and conditions as the license
+      granted to You under this License.
+   3. If any provision of this License is invalid or unenforceable under
+      applicable law, it shall not affect the validity or enforceability
+      of the remainder of the terms of this License, and without further
+      action by the parties to this agreement, such provision shall be
+      reformed to the minimum extent necessary to make such provision
+      valid and enforceable.
+   4. No term or provision of this License shall be deemed waived and no
+      breach consented to unless such waiver or consent shall be in
+      writing and signed by the party to be charged with such waiver or
+      consent.
+   5. This License constitutes the entire agreement between the parties
+      with respect to the Work licensed here. There are no
+      understandings, agreements or representations with respect to the
+      Work not specified here. Licensor shall not be bound by any
+      additional provisions that may appear in any communication from
+      You. This License may not be modified without the mutual written
+      agreement of the Licensor and You.
+
+Creative Commons is not a party to this License, and makes no warranty
+whatsoever in connection with the Work. Creative Commons will not be
+liable to You or any party on any legal theory for any damages
+whatsoever, including without limitation any general, special,
+incidental or consequential damages arising in connection to this
+license. Notwithstanding the foregoing two (2) sentences, if Creative
+Commons has expressly identified itself as the Licensor hereunder, it
+shall have all rights and obligations of Licensor.
+
+Except for the limited purpose of indicating to the public that the Work
+is licensed under the CCPL, neither party will use the trademark
+"Creative Commons" or any related trademark or logo of Creative Commons
+without the prior written consent of Creative Commons. Any permitted use
+will be in compliance with Creative Commons' then-current trademark
+usage guidelines, as may be published on its website or otherwise made
