 Thanks for checking out Searcher. Below are the instructions to get you up and running.
 
+## Note for Houdini 18.5  
+SideFX has only included SQLite v 3.31.0 with H18.5 and their support has told me they have no plans to upgrade it to 3.33.0 (which has FTS5 enabled (Full-Text Search), which is needed by Searcher). Because of this, an extra step is required to install/use Searcher with Houdini 18.5 until/unless they decide to include SQLite 3.33.0 instead of 3.31.0.
+
+Download:  
+Windows x64: [SQLite v3.33.0](https://www.sqlite.org/2020/sqlite-dll-win64-x64-3330000.zip)   
+- Extract the downloaded sqlite-dll-win64-x64-3330000.zip file, then in another window browse to your Houdini installation directory: aka `$HFS/bin`.  
+  By default this is located at: `C:\Program Files\SideFX\Houdini18.5.351\bin`
+- In the Houdini $HFS/bin folder, locate the `sqlite3.dll` file and either make a backup copy to save elsewhere (just in case), or simply rename it to `sqlite3.dll.bak`
+- From the extracted sqlite-dll-win64-x64-3330000.zip, locate the new `sqlite3.dll` then copy and paste it into the `$HFS/bin` folder.
+
+From my testing, that was all that needed to be done, as Searcher worked for me at that point, but Houdini support mentioned that the sqlite3.dll located in the `$HFS/python27/dlls` folder should be replaced as well. Just make sure to back it up/rename it as well. Always better to be safe than sorry!
+
+The process is the same for Unix OS's, you just have to go to the `$HFS/bin` folder that cooresponds to your particular OS and instead of looking for sqlite3.dll, the file will just be `sqlite3`. I would love to test it, but Houdini 18.5 on Linux crashes when I try to open it on both my laptop and VM on my desktop.  
+
+Linux: [SQLite v3.33.0](https://www.sqlite.org/2020/sqlite-tools-linux-x86-3330000.zip)   
+MacOS: [SQLite v3.33.0](https://www.sqlite.org/2020/sqlite-tools-osx-x86-3330000.zip)
