+<p>SQLite is an in-process library that implements a
+<a href="selfcontained.html">self-contained</a>,
+<a href="serverless.html">serverless</a>,
+<a href="zeroconf.html">zero-configuration</a>,
+<a href="transactional.html">transactional</a>
+SQL database engine.
+The code for SQLite is in the
+<a href="copyright.html">public domain</a> and is thus free for
+use for any purpose, commercial or private.
+SQLite is the <a href="mostdeployed.html">most widely deployed</a> database in the world
+with more applications than we can
+count, including several <a href="famous.html">high-profile projects.</a></p>
+
+<p>SQLite is an embedded SQL database engine.
+Unlike most other SQL databases, SQLite does not have a separate
+server process. SQLite reads and writes directly to ordinary disk
+files. A complete SQL database with multiple tables, indices,
+triggers, and views, is contained in a single disk file.
+The database <a href="fileformat2.html">file format</a> is cross-platform - you can freely copy a database
+between 32-bit and 64-bit systems or between
+<a href="http://en.wikipedia.org/wiki/Endianness">big-endian</a> and
+<a href="http://en.wikipedia.org/wiki/Endianness">little-endian</a>
+architectures. These features make SQLite a popular choice as
+an <a href="appfileformat.html">Application File Format</a>. SQLite database files are a
+<a href="locrsf.html">recommended storage format</a> by the US Library of Congress.
+Think of SQLite not as a replacement for
+<a href="http://www.oracle.com/database/index.html">Oracle</a> but
+as a replacement for <a href="http://man.he.net/man3/fopen">fopen()</a></p>
+
+<p>SQLite is a compact library.
+With all features enabled, the <a href="footprint.html">library size</a> can be less than 750KiB,
+depending on the target platform and compiler optimization settings.
+(64-bit code is larger. And some compiler optimizations
+such as aggressive function inlining and loop unrolling can cause the
+object code to be much larger.)
+There is a tradeoff between memory usage and speed.
+SQLite generally runs faster the more memory
+you give it. Nevertheless, performance is usually quite good even
+in low-memory environments. Depending on how it is used, SQLite can be
+<a href="fasterthanfs.html">faster than direct filesystem I/O</a>.</p>
+
+<p>SQLite is
+<a href="testing.html">very carefully tested</a> prior to every
+release and has a reputation for being very reliable.
+Most of the SQLite source code is devoted purely to testing and
+verification. An automated test suite runs millions and millions of
+test cases involving hundreds of millions of individual SQL statements
+and achieves <a href="testing.html#coverage">100% branch test coverage</a>.
+SQLite responds gracefully to memory
+allocation failures and disk I/O errors. Transactions are
+<a href="http://en.wikipedia.org/wiki/ACID">ACID</a>
+even if interrupted by system crashes or power failures.
+All of this is verified by
+the automated tests using special test harnesses which simulate
+system failures.
+Of course, even with all this testing, there are still bugs.
+But unlike some similar projects (especially commercial competitors)
+SQLite is open and honest about all bugs and provides
+<a href="https://www.sqlite.org/src/rptview?rn=1">bugs lists</a> and
+minute-by-minute <a href="https://www.sqlite.org/src/timeline">
+chronologies</a> of code changes.</p>
+
+<p>The SQLite code base is supported by an
+<a href="crew.html">international team</a> of developers who work on
+SQLite full-time.
+The developers continue to expand the capabilities of SQLite
+and enhance its reliability and performance while maintaining
+backwards compatibility with the
+<a href="c3ref/intro.html">published interface spec</a>,
+<a href="lang.html">SQL syntax</a>, and database <a href="fileformat2.html">file format</a>.
+The source code is absolutely free to anybody who wants it,
+but <a href="prosupport.html">professional support</a> is also available.</p>
+
+<p>The SQLite project was started on
+<a href="https://www.sqlite.org/src/timeline?c=2000-05-29+14:26:00">2000-05-09</a>.
+The future is always hard to predict, but the intent of the developers
+is to support SQLite through the year 2050. Design decisions are made
+with that objective in mind.</p>
+
+<p>We the developers hope that you find SQLite useful and we
+entreat you to use it well: to make good and beautiful products that
+are fast, reliable, and simple to use. Seek forgiveness for yourself
+as you forgive others. And just as you have received SQLite for free,
+so also freely give, paying the debt forward.</p>
