+				<h1 id="eulerbooks">Eulerbooks</h1>
+				<p>This is a collection of Jupyter notebooks containing solutions and
+				discussions for the first 100 <a
+					href="https://projecteuler.net">Project Euler problems</a> using <a
+					href="https://www.sagemath.org">SageMath</a>.</p>
+
+				<p>My main goal with these notebooks is not simply to provide working
+				code for solving the problems. Frequently, solutions to these problems
+				are short, but they’re not always easy to follow without understanding
+				some important mathematical principles. Therefore, my aim is to provide
+				insight into the underlying algorithms and mathematical concepts that
+				make an efficient solution possible. I personally find that these
+				topics are frequently even more interesting than the problems
+				themselves, which I see as mainly existing to provide situations to
+				apply the concepts after learning about them. In short, it’s more about
+				the journey, not the destination, so these notebooks mainly exist to
+				discuss the former.</p>
+
+				<h2 id="approach">Approach</h2>
+				<p>Frequently, either Python or SageMath provide functions and
+				libraries that make it trivially easy to write a solution. I don’t have
+				a problem with presenting solutions that use these, since for practical
+				purposes, it’s better to use what’s already available than to reinvent
+				the wheel. It also tends to lead to code that is easy to read and
+				understand, which is the best kind of code.</p>
+
+				<p>However, when a function already exists that does the heavy lifting,
+				I also tend to provide my own basic implementation and an explanation
+				of why it works. This is especially true if a solution or algorithm is
+				based off of an important mathematical concept that is not especially
+				intuitive.</p>
+
+				<p>When not especially tedious, I like writing up solutions that do not
+				require programming at all, since these approaches often require
+				interesting mathematical techniques.</p>
+
+				<p>Another thing to note is that I don’t prioritize a solution’s
+				performance above all. When a solution is fast enough (using Project
+				Euler’s own “one-minute rule” as a rule of thumb), I instead usually
+				focus on making the code easy to read. You can basically always
+				optimize, but there are frequently diminishing returns, and it tends to
+				negatively impact readability. Once a solution is fast enough to solve
+				the problem at hand, I only consider optimizing further if the concepts
+				are reusable.</p>
+
+				<h2 id="solutions">Solutions</h2>
+				<p>Solutions are provided as non-interactive HTML renderings that you
+				can view directly in your browser. Alternatively, you can download the
+				Jupyter notebooks to play with them yourself. I've also marked some of
+				my favorite problems.</p>
