 ## What’s nsrlsvr?
 The National Institute of Standards and Technology (NIST) maintains the National Software Reference Library (NSRL) — a giant compendium of software contributed by vendors.  It’s not a library in the sense that you can check things out from it, though: it’s more a library that you can check to see whether a given file already exists.  All the system files from Windows 7 are in the NSRL, as is the latest releases of Firefox and Opera and Chrome, Winamp and…

 It keeps track of 40 million hash values in an in-memory dataset and allows users to query that set at extremely high volume.  This allows an investigator using an NSRL tool (such as `nsrllookup`) to winnow through large numbers of files in a very short period of time.

+## Build instructions
+
+You will need:
+
+* The [source code](https://github.com/rjhansen/nsrlsvr/archive/1.7.0.tar.gz)
+* A _good_ C++14 compiler.  GCC 5.0 will work, barely.  On the latest GCC and Clang it hums nicely.
+* [CMake](https://www.cmake.org) 3.4 or later
+* [Boost](https://boost.org) 1.66 or later
+* A copy of the [minimal NSRL RDS](https://s3.amazonaws.com/rds.nsrl.nist.gov/RDS/current/rds_modernm.zip)
+
+Once you've uncompressed the latest archive, go into that directory and:
+
+```
+cmake -DPYTHON_EXECUTABLE=`which python3` -DCMAKE_BUILD_TYPE=Release .
+make
+sudo make install
+```
+
+You will need a database of hashes to load into `nsrlsvr`.  Extract the file `NSRLFile.txt` from `rds_modernm.zip` and run `nsrlupdate`:
+
+```
+sudo nsrlupdate /path/to/NSRLFile.txt
+```
+
+Once that's done you should be able to type
+
+```
+nsrlsvr
+```
+
+and have it start up.
