@@ -11,75 +11,9 @@ Nissy can also solve many different substeps of Thistlethwaite's algorithm
 (DR/HTR), and can use NISS (Normal-Inverse Scramble Switch).
 It can be useful to analyze your DR solves (and more, once I implement more features).
 
-## Why should I use Nissy?
-
-You should use Nissy if you:
-
-* Want to analyze your DR solutions or check for multiple optimal (or sub-optimal)
-solutions for EO/DR/HTR or similar substeps.
-* You just want a Rubik's cube solver and you like command line interfaces.
-* You want an alternative to Cube Explorer.
-
-## Requirements
-
-A full installation of nissy requires about 3Gb of space,
-of which 2.3Gb are occupied by the huge pruning table for fast optimal solving,
-and running it requires the same amount of RAM.
-One can choose to never use this function and not to install the relative
-pruning table. There is an alternative (slower)
-optimal solving function that uses about 500Mb of RAM.
-
-## Installation
-
-### On Windows
-
-Try downloading and executing in a terminal the file nissy.exe, then
-follow the instructions in the **Tables** section below for
-installing the pruning tables.
-If nissy.exe does not work, you can try following the UNIX instructions
-in WSL (Windows Subsystem for Linux) or in a similar environment.
-
-Sorry for the inconvenience, I don't have a Windows machine to test this on.
-
-### On a UNIX system:
-
-Edit the Makefile to match your local configuration (usually not necessary, but you
-may want to change the `PREFIX` variable) and run `make`, followed by `make install`.
-Follows the instructions below to install the pruning tables.
-
-### Tables
-Nissy needs to generate certain large tables to work. These tables are by default
-generated the first time they are needed (e.g the first time you ask to solve a
-certain step) and then saved to a file. Whenever these tables are needed again,
-nissy simply loads the corresponding file from the hard disk.
-
-The very large table for optimal solving can take some time to generate
-(about 1.5 hours on my fairly old but decent laptop, using 8 CPU threads).
-In order to generate it you need at least 5Gb or RAM.
-All other tables are much faster.
-
-You can ask Nissy to generate all the tables it will ever need with the `gen`
-command. It is recommended to use more than one thread, if your CPU has them.
-For example, you can run:
-
-```
-nissy gen -t 8
-```
-
-to generate all tables using 8 threads.
-
-Alternatively, you can simply download all the tables and copy them into the
-correct folder (see manual page, `ENVIRONMENT` section). On UNIX operating
-systems this folder is either `.nissy/tables` in the user's home directory or
-`$XDG_DATA_HOME/nissy/tables` if the XDG variable is configured. On Windows
-it is the same directory as the nissy.exe executable file.
-
-Choose either the
-[zip](https://nissy.tronto.net/nissy-tables-2.0.zip)
-or the
-[tar.gz](https://nissy.tronto.net/nissy-tables-2.0.tar.gz)
-file (click the links to download) and
-extract them in the correct folder.
+You get Nissy from [nissy.tronto.net](https://nissy.tronto.net). The download
+links and installation instructions can be found on the

+<h2>Installation</h2>
+
+<h3>System requirements</h3>
+
+<p>
+A full installation of nissy requires about 3Gb of space,
+of which 2.3Gb are occupied by the huge pruning table for fast optimal solving,
+and running it requires the same amount of RAM.
+One can choose to never use this function and not to install the relative
+pruning table. There is an alternative (slower)
+optimal solving function that uses about 500Mb of RAM.
+</p>
+
+<h3>Windows</h3>
+
+<p>
+Try downloading and executing in a terminal the file <code>nissy.exe</code>,
+then follow the instructions in the <strong>Tables</strong> section below for
+installing the pruning tables.
+If <code>nissy.exe</code> does not work, you can try following the UNIX instructions
+in WSL (Windows Subsystem for Linux) or in a similar environment.
+</p>
+
+<h3>UNIX (Linux, MacOS, *BSD...)</h3>
+<p>
+Edit the <code>Makefile</code> to match your local configuration
+(this is usually not necessary, but you may want to change the
+<code>PREFIX</code> variable to change the installation path)
+and run <code>make</code>, followed by <code>make install</code>.
+Follow the instructions below to install the pruning tables.
+
+<h3>Tables</h3>
+

+<p>
+<strong>Note:</strong> the version 2.0 at the end of the file name is
+only indicative. Later versionw will use the same tables, unless
+otherwise specified.
+</p>
+
+<p>
+Nissy needs certain large tables to work. These tables are by default
+generated the first time they are needed (e.g the first time you ask to solve a
+certain step) and then saved to a file. Whenever these tables are needed again,
+nissy simply loads the corresponding file from the hard disk.
+</p>
+
+<p>
+The very large table for optimal solving can take some time to generate
+(about 1.5 hours on my fairly old but decent laptop, using 8 CPU threads).
+In order to generate it you need at least 5Gb of RAM.
+All other tables are much faster.
+</p>
+
+<p>
+You can ask nissy to generate all the tables it will ever need with the gen
+command. It is recommended to use more than one thread, if your CPU has them.
+For example, you can run:
+</p>
+
+<pre><code>nissy gen -t 8</pre></code>
+
+<p>
+to generate all tables using 8 threads. You can change 8 to any number
+your CPU supports, up to 64.
+</p>
+
+<p>
+Alternatively, you can simply download all the tables and copy them into the
+correct folder (see manual page, <code>ENVIRONMENT</code> section). On UNIX
+operating systems this folder is either <code>.nissy/tables</code> in the
+user's home directory or <code>$XDG_DATA_HOME/nissy/tables</code> if the
+XDG variable is configured. On Windows it is the same directory as the
+<code>nissy.exe</code> executable file.

+Nissy v1 was released in 2020. It was slow, full of bugs and the code

+
+<p class=subtitle>A Rubik's cube solver and FMC assistant</p>
+
+<img src="/screenshot.png">
+
+<p>
+Nissy is a command-line Rubik's cube solver. It can find optimal solutions
+for random positions using techniques from Herbert Kociemba's
+<a href="http://kociemba.org/cube.htm">Cube Explorer</a> and
+Tomas Rokicki's
+<a href="https://github.com/rokici/cube20src/blob/master/nxopt.md">nxopt</a>.
+With 4 cores at 2.5GHz and using less than 3Gb of RAM, Nissy can find an optimal
+solution in about a minute on average.
+</p>
+
+<p>
+Nissy aims at being a complete tool
+for FMC (Fewest Moves Challenge) practice. It can solve different steps
+of Thistlethwaite's algorithm (also know as DR/HTR) and cans use NISS
+(Normal-Inverse Scramble Switch).
+</p>
+
+<p>
+You should use Nissy if:
+</p>
+<ul>
+<li>
+You want to analyze your DR solutions or check for multiple optimal
+(or sub-optimal) solutions for EO/DR/HTR or similar steps.
+</li>
+<li>
+You just want a Rubik's cube solver and you like command line interfaces.
+</li>
+<li>
+You want an alternative to Cube Explorer.
+</li>
+</ul>

+To get started, head to the <a href="/download/">download</a> page.
