+
+As every Apache project, so is `Apache IoTDB` generally available and usable 
by anyone free of charge.
+
+Also does the `Apache IoTDB Community` offer free support on the official 
project `Mailinglist`. This support is however, done voluntarily by the 
community, so there are no service-level-agreements, guaranteed reaction times 
or guarantee that an issue will be addressed or solved.
+
+If you or your business has higher demands on guaranteed availability and 
execution of support requests, the following individuals and companies have 
commercial support offerings.

+
+As every Apache project, so is `Apache IoTDB` generally available and usable 
by anyone free of charge.
+
+Also does the `Apache IoTDB Community` offer free support on the official 
project `Mailinglist`. This support is however, done voluntarily by the 
community, so there are no service-level-agreements, guaranteed reaction times 
or guarantee that an issue will be addressed or solved.

+If you or your business has higher demands on guaranteed availability and 
execution of support requests, the following individuals and companies have 
commercial support offerings.
