 To aid in playing Lexicon, Lexipython **does** provide the following:

 * HTML page generation and interlinking.

+To run a game of Lexicon with Lexipython, use [git](https://git-scm.com/) to clone this repository out to a new folder.
 ```
-$ git clone https://github.com/Jaculabilis/Lexipython.git [name]
+$ git clone https://github.com/Jaculabilis/Lexipython.git
 ```
 
-Steps for setup:
+Lexipython requires [Python 3](https://www.python.org/downloads/). It will run with only the Python 3 standard library installed, but pagerank statistics will be unavailable without `networkx` installed.
-1. [WIP]
+```
+$ pip install --user networkx
+```
+
+When you have the necessary software installed, open a terminal in the Lexipython directory. You can view the usage of the program with
+```
+$ python lexipython -h
+usage: lexipython [-h] [name] [command]
+
+Lexipython is a Python application for playing the Lexicon RPG.
+
+positional arguments:
+  name        The name of the Lexicon to operate on
+  command     The operation to perform on the Lexicon
+
+optional arguments:
+  -h, --help  show this help message and exit
+
+Run lexipython.py without arguments to list the extant Lexicons.
+
+Available commands:
+
+    init        Create a Lexicon with the provided name
+    build       Build the Lexicon, then exit
+    run         Launch a persistent server managing the Lexicon
+```
+
+Your lexicons are stored in the `lexicon/` folder. Run `python lexipython` to see the status of all lexicons. Except I haven't implemented that yet. Ignore that bit. If you run `python lexipython [name]`, you'll get the status of the named lexicon. That also hasn't been implemented. Whoops!
+
+To create a lexicon, run `python lexipython [name] init` with the name of the lexicon. A folder will be created in `lexicon/` with the given name and some default files will be copied in. You'll need to add a logo image to the folder and edit the config. As players submit articles, place the .txt files in `lexicon/[name]/src/`.
+
+When you finish your initial edits to the config and whenever you want to update the generated HTML files, run `python lexipython [name] build`. Lexipython will regenerate the article pages under `lexicon/[name]/article/` as well as the contents, formatting, rules, session, and statistics pages, and the editor.
+
+To publish the pages, simply copy the lexicon's folder to wherever you're hosting the static files. If you wish, you can leave out the `src/` directory and the status and cfg files. They're are not navigable from the public-facing pages.
+
+The `run` command isn't implemented yet either, and to be honest that probably isn't how you're supposed to implement it in the first place. Ignore it for now.
+
+## Configuring a lexicon
+
+[`lexicon.cfg`](lexipython/resources/lexicon.cfg) contains comments explaining the various config options. `PROMPT` and `SESSION_PAGE` should be written as raw HTML, and will be inserted directly into the page. If you wish to use the Addendums rule explained in the main readme, set `ALLOW_ADDENDA` to `True`. If `SEARCHABLE_FILE` is defined, then the Session page will link to a file with all the articles on one page.
+
+## Other notes
+
+At the end of the build, Lexipython will check for players citing themselves. The program does not fault on these checks, because players may be writing articles as Ersatz Scrivener, or otherwise allowed to cite themselves. Watch out for any unexpected output here.

When this happens, the player instead writes their article as **Ersatz Scrivener**, radical skeptic. Ersatz does not believe in the existence of whatever he is writing about, no matter how obvious it seems to others or how central it is in the developing history of the world. For Ersatz, all references, testimony, etc. with regard to its existence are tragic delusion at best or malicious lies at worst. Unlike the other scholars, Ersatz does not treat the research of his peers as fact, because he does not believe he has peers. Players writing articles as Ersatz are encouraged to lambast the amateur work of his misguided "collaborators".

 ## Procedural Rules: Running the Game
 
 ### The Editor
@@ -60,7 +64,7 @@ The player running the game is the Editor. The Editor should handle the followin
 
 * **Topic statement.** The topic statement should be vague, but give the players some hooks to begin writing. Examples: "You are all revisionist scholars from the Paleotechnic Era arguing about how the Void Ghost Rebellion led to the overthrow of the cyber-gnostic theocracy and the establishment of the Third Republic"; "In the wake of the Quartile Reformation, you are scholars investigating the influence of Remigrationism on the Disquietists". What happened to the first two Republics or what Remigrationism is are left open for the players to determine.
 
-* **Indices and turns.** In general, the Editor will decide on a number of turns and divide the alphabet into that many indices. Each player then takes one turn in each index. A game of 6 or 8 turns is suggested. _Example: An 8-turn game over the indices ABC/DEF/GHI/JKL/MNO/PQRS/TUV/QXYZ._ The Editor should determine how much time the players can devote to playing Lexicon and set a time limit on turns accordingly.

 * **Index assignments.** Each turn, the Editor should assign each player to an index. Unless players have a method of coordinating who is writing what article, it is suggested that the Editor always assign players to write in different indices. The easiest way to do this is to distribute players randomly across the indices for the first turn, then move them through the indices in order, wrapping around to the top from the bottom.

 * Even if articles don't get too long, having too many articles on one subject can lead to the same problem of writing on the topic becoming too hard to do consistently. Avoid having multiple articles about the same thing, and avoid having too many articles about different facets of one particular element of the world.
 
-* Encyclopedias are written about things in the past. Players may, of course, want to mention how something in the past still affects the world in the present day. However, if players begin to write about purely contemporary things or events, the Lexicon shifts from an _encyclopedic_ work to a _narrative_ one. If that's what you want out of the game, go ahead and do so, but writing about an ongoing narrative insead of settled history introduce the additional complication of keeping abreast of the current state of the plot. It is more difficult for players to avoid contradiction when the facts are changing as they write.

 The Editor is always free to alter the game procedures when it would make for a better game. The following are some known rule variations:
 
-* **Follow the Phantoms:** Players make two phantom citations on the first turn. On subsequent turns, rather than choosing from phantoms and open slots in an assigned index, players must write an existing phantom. Until all slots are full, players must make one of their phantom citations to a new phantom article and one to an existing phantom.
+* **Follow the Phantoms:** Players make phantom citations as normal on the first turn. On subsequent turns, rather than choosing from phantoms and open slots in an assigned index, players must write an existing phantom. Until all slots are full, players must make one of their phantom citations to a new phantom article and one to an existing phantom.
+
+* **Addendums:** In addition to writing new and phantom articles, players can write articles with the same title as an already-written article. The content of these "addendum" articles is added as a postscript at the bottom of the first article written under that title. Addendums can legally cite what their author can cite, not what the main article's author can cite.
 
 * Occasionally, if more players make a citation to an index than there are open slots, the index will be over capacity. If the Editor is assigning players to indices in order, the Editor may need to shift players' index assignments around. This may also be useful for decreasing the number of Ersatz articles, if a player can't write in their assigned index but could write in another.
