 # Scimitar
 ## Ye Distributed Debugger
 
-### GDB Integration
-* The scripts are in the
-  [tools](`https://github.com/parsa/scimitar/tree/master/tools`) directory.
-* To import the printers:
-    * If your GDB is set up to perform auto loading simply copy `auto-load` and
-      `python` directories to the appropriate locations.
-    * If you're not using auto-load then ensure the path to auto-load and
-      Python directories are in `sys.path`
-        * One option to add them to GDB Python's sys.path is running `python
-          sys.path.append(`'<PATH_TO_DIR>'`)` for both directories.
-    * Run `python import scimitar_gdb` inside GDB
-    * You can also put the commands inside your `.gdbrc`
+Scimitar is a distributed debugging tool for HPX applications. It is a front-end for GDB and adds features to make common operations such as switching between several sessions (like localities in HPX) and viewing HPX's internal data structures easier.
 
-```
-python
-sys.path.extend([
-    '<path to scimitar-gdb directory>/auto-load',
-    '<path to scimitar-gdb directory>/python',
-])
-import scimitar_gdb
-end
-```
+### Documentation
+* For documentation consult [Scimitar's wiki pages](https://github.com/STEllAR-GROUP/scimitar/wiki)
 
-### Prerequisites
-* Software:
-  * Python 2.7
-  * GDB 7.1
-* Python Modules
-  * pexpect
-
-### Configuration
-In order to prevent having to enter the debugging environment configurations
-every time it is launched and save time Scimitar uses the file
-`utils/config.py` to retrieve the configurations of a cluster. You may modify
-and add to it to meet your needs.
-
-### Running
-* Schedule a job to run your application. Ensure mpirun starts.
-* Run `scimitar.py` on your machine
-* Start a session by `remote <host> <scheduler job id>`
-* Once you're connected you can switch between localities by using the command
-  `switch <locality id>`
-
-## Commands
-* local raw
-* local <pid>[ <pid>...]
-* local ls
-* local ls <regex_pattern>
-* remote <machine_name>
-* remote <machine_name> <jobid>
-* remote <machine_name> attach <app_name> <node:pid>[ <node:pid>...]
