   +UPGRADE NOTES

   + * If you're upgrading from <= alpha3, the module must be UNINSTALLED first.
   

   This applies to the D6 version of Feeds Tamper. There is no alpha3 version for Feeds Tamper 7.x-1.x.
   Should be removed.

Updated the patch from #2 according to the comments in #4. Also fixed some grammar / spelling.

Updated patch with README template (https://www.drupal.org/docs/develop/documenting-your-project/readme-temp...)

Testing fails because CTools is using short array syntax and we are using tests with php 5.3 . Changed the php version used for testing.

   +Your can add tampers on the TAMPER tab while editing your Feeds importer.
   

   "Your can add tampers" doesn't sound like proper English. I'm also not sure why "TAMPER" should be all caps. This should probably be rephrased a bit. Explain how to get to Tamper configuration, how adding Tampers work and that they can be rearranged.

   It's probably enough to just link to the documentation.

   Neither I nor Chris are currently actively maintaining the D7 version of this module (you could say though that I’m passively maintaining it). I'm mainly working on the D8 version. Not sure how to rephrase that, but "Current" seems a bit out of place.

Worked on @dhruveshdtripathi 's patch to incorporate @MegaChriz 's comments

I made a few changes to the readme and committed the result.

Changes:

1. In 'Introduction' links are added to the plugin list, the contributed plugin list and a page that explains how to develop your own plugin.
2. In 'Installation', it is mentioned that Feeds Tamper Admin UI needs to be enabled in order to configure tampers in the UI.
3. In 'Configuration' the two paragraphs are flipped.
4. A few changes in the formatting (extra new lines and making sure that all lines fit on 80 chars).
