+
+## INSTALLING ##########################################################
+
+ * Requires: Python 2.7 or 3.3+
+ * pyproj (optional but highly recommended), this speeds up tests, makes
+ results more precise but has the trade-off of making installation a
+ little more complicated.
+
+
+
+### Installing pyproj ##################################################
+
+ 1) Install `pip` (usually `pip3`) if not installed, should already be installed on new Python
+ versions (Python 3 >=3.4) or if using a virtual environment for python.
+ see https://pip.pypa.io/en/stable/installing/
+ * **Note**: if you have Python 2.x and 3.x installed, `pip3` is for Python 3.x.
+ `pip` could be an alias for either one.
+ 2) Upgrade `pip` (possibly not needed)
+ https://pip.pypa.io/en/stable/installing/#upgrading-pip
+ 3) Install pyproj
+ * requires a C/C++ compiler be usuable by python
+ * repository version requires Cython to be installed, releases do not require this
+
+```
+ $ pip install cython
+```
+
+ * install latest release
+ * set PROJ_DIR environment variable to an installed version of PROJ4
+ library. This should have the directories include/ lib/ &
+ share/proj/ underneath it.
+
+ * installing on Linux (default ./configure settings for PROJ.4)
+
+```
+ $ PROJ_DIR=/usr/local pip install pyproj
+```
+
+## Running Tests #######################################################
+
+When calling test_json.py it defaults to using pyproj driver.
+
+```
+ $ python test_json.py 5*.json
+```
+
+There is a driver to directly use cs2cs instead of installing pyproj, but
+it is much slower and not recommended.
+
+Here is how you run the cs2cs driver:
+
+```
+ $ python test_json.py -d cs2cs -e path/to/repo/bin/cs2cs 5201.json
+```
+
+
+## GIGS Test ###########################################################
+
+Tests that were meant to test for out of grid errors were removed from
+testing. PROJ.4 cs2cs provides coordinates seemingly without warnings
+or errors.
+
+### Drastic Tolerance Errors ###########################################
+
+These are errors that might indicate the wrong projection is being used,
+wrong parameters are being used in the projection, or problems with the
+projection itself. It could point to problems with the provided model.
+
+ * 5101 part 4 - Transverse Mercator
+ - EPSG code will need to be redefined to make sure that etmerc version
+ is used, should be done before next release (4.9.3 / 4.10.0 ?)
+ - Temporarily use test "5101.4-jhs-etmerc.json", perhaps remove file
+ when etmerc/tmerc aliasing issue has been fixed.
+ * 5102 part 2 - Lambert Conic Conformal (1SP)
+ - This one seems to have some problems.
+ * 5105 part 1 - Oblique Mercator (variant B)
+ - There are some drastically different answers.
+
+### Slight Tolerance Errors ############################################
+
+These tests have results with rounding errors that are slightly out of
+tolerance. This could be due to a lack of precision in the JSON file
+or due to the formula's precision. Most of these tests fail with some
+point in testing 1,000 round trip coordinate conversions. A few of these
+might require a little bit of tuning with cs2cs. There are some rather
+concerning differences between Python 2.7 and Python 3.4 in testing, which
+needs to be pinpointed.
+
+ * 5101 part 1 - Transverse Mercator
+ - roundtrip tests fail with very slight tolerance issues
+ * 5104 - Oblique stereographic
+ - roundtrip tests fail with very slight tolerance issues
+ * 5105 part 2 - Oblique Mercator (variant B)
+ - roundtrip tests fail with tolerance issues
+ * 5106 - Hotline Oblique Mercator (variant A)
+ - roundtrip tests fail with very slight tolerance issues
+ * 5108 - Cassini-Soldner
+ - roundtrip tests seem to accumulate errors
+ * 5110 - Lambert Azimuthal Equal Area
+ - roundtrip tests have some slight errors
+ * 5111 part 1 - Mercator (variant A)
+ - roundtrip tests fail with very slight tolerance issues
+ * 5111 part 2 - Mercator (variant A)
+ * 5203 part 1 - Position Vector 7-parameter transformation
+ - most seem to be rounding errors. Some results cross longitude
+ line 180/-180
+ * 5204 part 1 - Coordinate Frame 7-parameter transformation
+ - most seem to be rounding errors. Some results cross longitude
+ line 180/-180
+ * 5205 part 1 - Molodensky-Badekas 10-parameter transformation
+ - most seem to be rounding errors. Some results cross longitude
+ line 180/-180
+ * 5206 - NADCON transformation
+ * 5207 parts 1 & 2 - NTv2 transformation
+
+
+### Other Issues with Tests ############################################
+ * 5201 - Geographic Geocentric conversions
+ - EPSG code 4979, does not exist in PROJ.4 substituted EPGS code 4326.
+ - The test passes.
+ * 5206 and 5207 parts 1 & 2 - NADCON Transformation and NTv2 Transformation
+ - These tests have cases that are out of grid, which have been omitted.
+ The GIGS tests expectations, "[n]ote 1: This location is out of
+ transformation grid area - the attempted transformation should fail
+ and application notify user."
+
+
+## Passing Tests #######################################################
+ * 5101 part 2 - Transverse Mercator
+ * 5101 part 3 - Transverse Mercator
+ * 5102 part 1 - Lambert Conic Conformal (1SP)
+ * 5103 part 1 - Lambert Conic Conformal (2SP)
+ * 5103 part 2 - Lambert Conic Conformal (2SP)
+ * 5103 part 3 - Lambert Conic Conformal (2SP)
+ * 5107 - American Polyconic
+ * 5109 - Albers Equal Area
+ * 5112 - Mercator (variant B)

+## Benchmarks ##########################################################
+
+Benchmarks were made using Micah Cochran's circa 2008 Desktop computer
+using LXLE Ubuntu Linux 14.04. The pattern "5*.json" was used for testing.
+
+This is the computer time used for the process, not the actual run time.
+ * pyproj driver testing 5 seconds
+ * cs2cs driver testing - using Python 2.7.6 - 4 min 36 seconds
+ * cs2cs driver testing - using Python 3.4.3 - 6 min 23 seconds
+
+
+
+## Random Notes #######################################################
+Roundtrip testing has been fixed, it now checks both resulting coordinates.
+
+Some tests in the 5100/5200 series have not been converted. The most of
+the 3d coordinate test in the 5200 series have not been converted.
+
+This is designed to use decimal degrees over Sexagesimal degree or degree
+minutes seconds, which is a decision that might need to be revisited.
+Decimal degrees were chosen because it was easier interface with the
+Python pyproj library. This might be the cause of some testing tolerance
+issues.
+
+pyproj and cs2cs drivers do not quite work the same. Different tests
+fail depending on the driver.
+
+Other drivers could be written to interface with other code.
+
+There could be some precision issues with cs2cs, perhaps some adjustment
+of the "-f format" parameter could help. This could be done based either
+on expected output or extra info from the JSON file.
+
+A TODO list is located source code.
+
+Conversion tests the output coordinate, causing 2 test results per
+coordinate pair.
+
+Roundtrip tests the input coordinate and the output coordinate of each
+ pair, causing 4 test results per coordinate pair.
