+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# mhchem Parser
+
+mhchem is an input syntax for typesetting chemical equations and physical units.
+
+This is the parser to convert mhchem syntax to LaTeX syntax, for downstream inclusion in [MathJax](https://mathjax.org), [KaTeX](https://katex.org) and similar projects.
+
+
+## Usage
+
+Users of MathJax and KaTex can write
+
+    \ce{CO2 + C -> 2 CO}
+    \pu{123 kJ*mol-1}
+
+For a hundred more features and how to configure MathJax or KaTeX, see
+[the manual](https://mhchem.github.io/MathJax-mhchem/).
+
+
+## Usage for Downstream Software
+
+For "translating" the `\ce` syntax, make a call like
+
+    mhchemParser.toTex("CO2 + C -> 2 CO", "ce");
+
+This will return
+
+    "{\mathrm{CO}{\vphantom{A}}_{\smash[t]{2}} {}+{} \mathrm{C} {}\mathrel{\longrightarrow}{} 2\,\mathrm{CO}}"
+
+For the `\pu` command, call
+
+    mhchemParser.toTex("123 kJ*mol-1", "pu");
+
+You could also insert a TeX string. All instances of `\ce` and `\pu` will be replaced in the returned value. This might make integration easier, because the mhchem parser does not need to be called from the TeX parser.
+
+    mhchemParser.toTex("m_{\\ce{H2O}}", "tex");
