+# Building Zipr/Peasoup
+
+The instructions that follow assume that:
+
+* you have access to both the Zipr and ZAFL repo
+* you have sudo privileges
+* you are installing in your home directory
+* you are using a recent version of Linux, e.g., Ubuntu 18.04
+
+
+First install the Zipr static binary rewriting infrastructure
+```
+cd ~
+git clone --recurse-submodules https://git.zephyr-software.com/allnp/zafl_umbrella.git # or git@git.zephyr-software.com:opensrc/peasoup_umbrella.git
+cd peasoup_umbrella
+. set_env_vars
+./get-peasoup-packages.sh all
+scons -j3
+```
+
+# Preparing Zipr for Use (Setting up local postgres tables)
+
+Next we need to setup the proper tables in a local copy of the postgres database.
+```
+cd ~/peasoup_umbrella
+./postgres_setup.sh
+```
+
+If all goes well with the postgres setup, you should be able to login into the database by typing: psql
+The output of psql should look something like this:
+```
+psql (9.3.22)
+SSL connection (cipher: DHE-RSA-AES256-GCM-SHA384, bits: 256)
+Type "help" for help.
+
+peasoup_XXX=>
+```
+
+# Testing Zipr
+
+Test the binary rewriting infrastructure by rewriting /bin/ls
+```
+cd /tmp
+$PSZ /bin/ls ls.zipr -c rida
+```
+Your terminal's output should look like this:
+```
+Using Zipr backend.
+Detected ELF file.
+Performing step gather_libraries [dependencies=mandatory] ...Done. Successful.
+Performing step meds_static [dependencies=mandatory] ...Done. Successful.
+Performing step pdb_register [dependencies=mandatory] ...Done. Successful.
+Performing step fill_in_cfg [dependencies=mandatory] ...Done. Successful.
+Performing step fill_in_indtargs [dependencies=mandatory] ...Done. Successful.
+Performing step clone [dependencies=mandatory] ...Done. Successful.
+Performing step fix_calls [dependencies=mandatory] ...Done. Successful.
+Program not detected in signature database.
+Performing step zipr [dependencies=clone,fill_in_indtargs,fill_in_cfg,pdb_register] ...Done. Successful.
+```
+
+Invoke the rewritten version of /bin/ls and make sure it runs normally:
+```
+./ls.zipr
+```

-Steps to installing.
-
- 0) Unpack the tarball (likely called zipr_toolchain.tgz) -- you must have done this already
- to be reading this!
- 1) Switch to the directory created during unpacking. i.e., cd zipr_toolchain
- 2) Run "source set_env_vars"
- 3) Run "./ubuntu16_files/install.sh" in this directory -- lots of packages
- will be installed.
- 4) Copy your ida.key for IdaPro7.0 to ./idaproCur/ida.key. Alternately, if you have a UVA CS
- account, you can use the UVA-CS dependability group's IDA server. To use this, run
- "source set_ida_server".
- 5) Run "postgres_setup.sh"
- This step sets up postgres to hold the Zipr database. If you already
- have postgres configured, it may damage your data. Use with appropriate caution.
- 6) Test the installation:
- run "cd /tmp; $PSZ /bin/ls ./ls.ziprd"
- You should see the Zipr toolchain protecting /bin/ls and writing results into the file
- The Zipr toolchain should report success if installed properly.
- Run the rewritten program as if it were /bin/ls: "/tmp/ls.ziprd"
-
-
-If you log out and log back in (or log into a new session), you'll need to re-run steps 1 and 2
-before using the toolchain again. You may wish to automate this step by adding it to your .bashrc
-file or other, appropriate login files.
